Share your Debian SCRIPTS

#1 Post by fabien »

Share your Debian scripts!
Why keep those valuable pieces of code out of sight?
Being of personal use, their polish is perhaps not as high as if you'd made them to be published (which takes time for sure): that's no matter, you wrote them because they are of some use for you, they may be so for others. And maybe someone will find the idea of interest, be inspired, and share a more accomplished version in turn (it's amazing how small scripts can become huge). Also, it will show to those who don't script yet that even without real programming knowledge everyone can achieve things that enhance day-to-day computer experience.
Again, it's their usefulness that makes their value, not the skills put on them nor is it their length or the time they required to be made (could even be a one-liner). If there should be a criterion it would be that you use them regularly.
And a rule of importance: they must be in one way or another Debian related since it is a Debian forum.
I really look forward to seeing new scripts and hope you'll keep this thread alive.

apt-fly
an interface for apt-file.

apt-fly help [large image]
apt-fly search [large image]
apt-fly binaries search [large image]
apt-fly shared files [large image]
apt-fly alternative sources [large image]
apt-fly work on packages [large image]

edit 2023-01-16: updated apt-fly from v.2.4 to v.3.0
- can now query alternative sources thanks to the schow-pkg framework
- it is now possible to select arbitrary packages to work on
- readline completion is now available
- several important fixes and improvements

edit 2023-11-09: updated apt-fly from v.3.0 to v.3.1
- licensed under GPLv3+
- some improvements and edge case fixes
- can now query "All available sources" (can be memory exacting)

edit 2023-11-13: updated apt-fly from v.3.1 to v.3.2
- working on arbitrary packages is no longer limited by the maximum length of system arguments,
in other words, it is now possible to work with as many packages as one likes
(this was previously possible, but extremely slow)

edit 2024-02-06: updated apt-fly from v.3.2 to v.3.3
- if the Release file of a Debian (apt) repository does not contain the
'No-Support-for-Architecture-all: Packages' field, clients split the Packages files between
'binary-all_Packages' and 'binary-$ARCH_Packages'. This is not yet the case for Debian
repositories, but it is for some repositories. This version takes this into account, and
this has also been corrected in schow-pkg v.5.1 and why-pkg v.0.11a.
- the Debian Policy Manual does not stipulate that the Package: field must be placed in the first
position in the stanza, and some (non-Debian) repositories actually place it elsewhere.
This can have consequences and has been corrected in this version as well as in schow-pkg v.5.1
and why-pkg v.0.11a.

edit 2024-02-24: updated apt-fly from v.3.3 to v.3.4
- fixed a regression introduced in v.3.3

why-pkg
an interface for 'aptitude why' (with handy 'aptitude search' interface), plus a function that displays recursive dependencies, and a function that examines system packages state.

why-pkg [large image]
why-pkg loop mode [large image]
why-pkg search with --showpatterns [large image]
why-pkg recursive dependencies [large image]
why-pkg recursive dependencies with installed reverse dependencies count [large image]
why-pkg audit [large image]
why-pkg help [large image]

edit 2022-05-29: updated why-pkg from 0.8b to 0.8c (added APT pinning test to --audit function)

edit 2022-11-20: Howto change why-pkg name:
  • [>] Changing why-pkg's name implies some easy but not so obvious steps.
  • line 4: replace why-pkg with new-name (limitation: new-name must not end with a digit)
  • line 139: replace _why-pkg() { with _new-name() {
  • line 250: replace complete -F _why-pkg why-pkg with complete -F _new-name new-name
  • and also replace them in /etc/bash_completion.d/why-pkg if relevant
  • mv /etc/bash_completion.d/why-pkg /etc/bash_completion.d/new-name if relevant
  • run new-name and replace new-name last line as stated: new-name v.x sha256sum
  • run new-name -N to check application
  • please note that apt-fly and schow-pkg have calls to why-pkg, so you'll have to change it there too

edit 2023-01-16: updated why-pkg from v.0.8c to v.0.9a
- updated to welcome changes in upcoming Bookworm
- new Bash completion function, please update /etc/bash_completion.d/why-pkg
- virtual packages are now highlighted in search results (f_why)
- new -E option: exclude virtual packages from search results (f_why)
- new -U option: apply pin priority 990 to given suite (f_why, f_reverse)
- new -V option: display not installed dependencies vertically (f_reverse)
- added missing enhancement packages detection (f_audit)

edit 2023-11-09: updated why-pkg from v.0.9a to v.0.10a
- cleanup and improvement of some parts of the code, some fixes too
- new Bash completion function, please update /etc/bash_completion.d/why-pkg
- new -A option: display aptitude search patterns (f_why)
- new -M option: query alternative sources among those provided by schow-pkg (f_why, f_reverse)
- new -P option: display colored output of apt-rdepends recursive reverse dependency listings (f_why)
- new -X option: like -x, but outlines the reasons for the checks and points the way for further study (f_audit)

edit 2024-02-06: updated why-pkg from v.0.10a v.0.11a
- due to occurrences, a warning is issued if the APT database has not been correctly updated (f_audit)
- remaining dependencies on debtags have been removed and its installation is discouraged
- new Bash completion function, please update /etc/bash_completion.d/why-pkg
- added 'provided by' information for real packages when using c/C/y/Y options (f_why)
- new -Z option: count all possible installed reverse dependencies for each package (f_reverse)

Most of my scripts - https://gitlab.com/jmgibson1981/homescr ... ster/shell
My Router config script to be run on boot - https://gitlab.com/jmgibson1981/homescr ... ter/router

Aren't much but they get it done.

*EDIT* And just now looking over them I have my sql dump script missing something. I probably removed the emergency email function and forgot to remove that variable.

I'm a fan of keeping things lightweight. clockspeed.sh, monitor CPU clockspeed:

Code: Select all

#!/bin/bash
watch -n.5 "grep \"MHz\" /proc/cpuinfo"
video2gif.sh, convert video segments into animated gifs:

Code: Select all

#!/bin/bash
ffmpeg -i "$1" -ss "$5" -t "$6" -filter_complex "[0:v] fps="$4",scale="$3":-1" "$2" -hide_banner
Takes arguments as video2gif.sh input.mp4 output.gif <resolution width> <fps> <start time> <duration>

thanks for your input @jmgibson1981, good examples of system scripts, and some are even Debian related.

Sometimes I wish I was like you, I can't help building big machines. This is why-pkg tiny quick and dirty first version:

Code: Select all

#!/bin/bash

[[ -z "$@" ]] && { echo -e "\n$(basename "$0"): cette commande a besoin d'au moins un paramètre (le paquet à rechercher).\n"
                             exit 1; }

for PKG in "$@" ; do

    sed 's/\(^.A\)\( \)/\1/')
   [[ -n "$PKGINFO" ]] && { echo "$PKGINFO" | grep -q "^i" && STATE="\ue008" || STATE="\e[0;90m\ue008\e[0m"; }
   [[ -n "$PKGINFO" ]] && echo -e "$(echo "\n\n$STATE $PKGINFO" | mawk 'sub($3,"\e[4m&\e[0m")')" ||\
    echo -e "\n\n\ue469 --    $PKG     - inconnu"

   RAW="$(aptitude -v why "$PKG")\n"
   [[ $(echo "$RAW" | grep "No dependencies require to install $PKG") ]] && { echo -e "\n$RAW" | sed 's/\(^.\)/  \1/'; continue; }

   echo -e "\n$(echo -e "$RAW" | grep -B1 "^$" | grep -v "^$" | grep -v "^--$" |\
    sed 's/\(^.\)\( \)\(.\)/\1\3/' | sed 's/[[:space:]]\+/ /g' | sed 's/[[:space:]]\+$//' | sed 's/ | /|/g' | sort -u |\
    mawk 'sub($2,"\e[1;37m&\e[0m"){printf "  %-4s %-45s %-0s %-0s\n",$1,$2,$3,$4}' |\
    sed 's/Dépend/\\e[1;35m&\\e[0m/' | sed 's/Recommande/\\e[1;36m&\\e[0m/' | sed 's/Suggère/\\e[0;36m&\\e[0m/')\n\n"

done

It selects the maximum frequency of all cores. This has to be adapted to the number of cores (here for 8 cores) and the particularities of 'sensors' output. The output is:

Code: Select all

I used to build big scripts, such as backup utilities, but found that they quickly became hard for me to identify and fix their eventual issues. And asked myself why was I putting effort into so much abstraction when I knew I would be the only person running that script, on some very familiar hardware.

Yep. Sorry. Didn't catch the part for Debian specific stuff. I only use Debian so just popped em up.

updated why-pkg from 0.8b to 0.8c (added APT pinning detection test to --audit function). See above.

tardcircus wrote: 2022-05-29 18:07or just whatever works on deb.
I wonder what kind of script wouldn't work on deb :o The idea is (was?) to collect scripts that help users with aspects of the Debian system, Debian related as I said in the introduction (sorry if it wasn't clear enough, I thought it was but my English is approximate). For example, I started working on apt-fly one day when I couldn't remember what package provided the 'play' command: 'apt-file search play' outputs over 30000 lines and it takes a long time to find out the answer that is found in seconds with apt-fly. Anyway, I find any input in this thread nice after all. However, maybe someone should take the initiative to open a new thread in Offtopic for non-Debian related scripts :)

@fabian: thanks for the contributions, very interesting. You might want to pass them through https://shellcheck.net, I use it for all my (lame) scripts, it's great for picking up shell script bugs and other problems.

For example, from apt-fly:

Code: Select all

Line 42:
DECOMPRESSIONMETHOD="$(ls -1 /var/lib/apt/lists/*_Contents-* 2>/dev/null |\
                       ^-- SC2010 (warning): Don't use ls | grep. Use a glob or a for loop with a condition to allow non-alphanumeric filenames.
So perhaps consider

Code: Select all

files=(/var/lib/apt/lists/*_Contents-*)
DECOMPRESSIONMETHOD="${files[@]##*.}"
HTH

EDIT:
fabian wrote:I couldn't remember what package provided the 'play' command: 'apt-file search play' outputs over 30000 lines
How about

Code: Select all

apt-file search "/usr/bin/play" # or perhaps "/(?:usr/bin/play)"

Thanks for your interest and your comments. I have shellcheck package installed and its analysis I have already questioned and addressed. It is actually useful but often fastidious and you have to take it with a grain of salt. For example, SC2010 rationale points out a real question that must be pondered:
Parsing ls is generally a bad idea because the output is fragile and human readable.
But the files in /var/lib/apt/lists/ are very unlikely to have special characters in them and even if it were the case I'm only interested in file extensions already defined as "\.bz2$\|\.gz$\|\.lz4$\|\.lzma$\|\.xz$\|\.zst$" so the probability of a glitch is zero.
Head_on_a_Stick wrote: 2022-05-30 15:00So perhaps consider

DECOMPRESSIONMETHOD="${files[@]##*.}"
I like full Bash solutions very much (take a look at the beginning of why-pkg for instance) and tend to use them as much as possible. But here using grep is the right choice since it ensures that no extension other than bz2, gz, lz4, lzma, xz, or zst are kept. Using find instead of ls will satisfy shellcheck.

Code: Select all

$> FILES=( /var/lib/apt/lists/*_Contents-* ); FILES=( "${FILES[@]##*.}" )
$> sort -u -k1,1 -- <<<"${FILES[@]/#/$'\n'}"
diff_Index
lz4

$> find /var/lib/apt/lists/ -maxdepth 1 -name "*_Contents-*" | grep -o "\.bz2$\|\.gz$\|\.lz4$\|\.lzma$\|\.xz$\|\.zst$" | sort -u
.lz4
But we shouldn't talk about technique here. Everyone is allowed to take the code or the idea, rewrite it and let us enjoy it.

If you use MATE or another desktop where the file manager is capable of two panels but doesn't or can't open both automatically then this, as simple as it gets, is a godsend.

Code: Select all

#!/bin/bash
# Open caja and then open second pane
caja $1 && sleep 0.5 ; xdotool key --clearmodifiers F3
Needs xdotool and I use it as the command for an icon on my toolbar. The sleep time does result in a noticeable (barely) gap from application opening to second panel opening and may be reduced,

Nice trick @NFT5, one that is worth remembering to solve hopeless case.
Thanks @user6c57b8, below is a quick prototype inspired by your one-liner.

Code: Select all

#!/usr/bin/env bash

declare -a DEPS MANUALS PKDEPS

LANG="C"  ### better performances and no UTF-8 expected
INSTALLEDPKGS="$(dpkg -l | mawk 'FNR>5{if (/^.i. /){$0=$2; sub(/:.+$/,""); print " "$0" "}}')"
command -v aptitude &>/dev/null && VIRTUALS="$(aptitude -F " %p " search "?virtual(^)" | grep -v ":")"
read -d '' -ra MANUALS < <(apt-mark showmanual)
readarray -t PKDEPS < <(dpkg-query -f '[\\e[1;31m${binary:Package}\\e[0m] ${Recommends}\n' -W "${MANUALS[@]}" |\
                        sed 's/ ([^)]\+)//g')

for PKG in "${PKDEPS[@]}"; do

   [[ "${PKG#* }" ]] || continue
   echo -en "${PKG%% *}  "
   read -d '' -ra DEPS <<<"${PKG#* }"
   for DEP in "${DEPS[@]}"; do

      [[ "$DEP" == "|" ]] && { echo -en "\e[0;33m$DEP\e[0m"; SPACE=""; continue; }
      [[ "$INSTALLEDPKGS" =~ " ${DEP%,} " ]] && { echo -en "$SPACE\e[0;37m$DEP\e[0m"; SPACE=" "; continue; }
      [[ "$VIRTUALS" =~ " ${DEP%,} " ]] && { echo -en "$SPACE\e[38;5;21m$DEP\e[0m"; SPACE=" "; continue; }
      echo -en "$SPACE\e[1m$DEP\e[0m"; SPACE=" "

   done
   echo

done

Output the /BIN/ commands of all the packages you have "manually" installed on your Debian system

#20 Post by user6c57b8 »

(see: post subject)

VERSION 2 (latest) (2022-07-10) (changes: added blue color to the output command.) (open bugs: some people reported some bin paths are invalid bin paths.)

Code: Select all

for str_package_name in $(apt-mark showmanual); do str_package_filelist_bin="$(dpkg --listfiles "$str_package_name" 2>/dev/null | egrep bin/ | sed 's/^/  /')"; [[ "$str_package_filelist_bin" ]] && { echo "<$str_package_name>"; echo "$str_package_filelist_bin" | sed 's/\/\([a-zA-Z0-9._-]\+\)$/\/\x1b[34m\1\x1b[39m/'; echo "</$str_package_name>"; } ; done





VERSION 1 (2022-06-10)

Code: Select all

#list the *bin/* (ie. command-line/terminal-executable/tty-executable programs) of all of the manually installed (apt install or dpkg -i) packages installed on your computer/PC
for str_package_name in $(apt-mark showmanual); do str_package_filelist_bin="$(dpkg --listfiles "$str_package_name" 2>/dev/null | egrep bin/ | sed 's/^/  /')"; [[ "$str_package_filelist_bin" ]] && { echo "<$str_package_name>"; echo "$str_package_filelist_bin"; echo "</$str_package_name>"; } ; done
