[Solved] Bash align text with printf

Postby Allain » 2017-06-26 16:54

Good evening

I have tried how to align text correctly
I can't get better than this
What can i do ?

The text file i am using :
    PK 744 - Hide Activities Button - User - Enabled -
    PK 72 - Recent Items - User - Disabled -
    PK 584 - TaskBar - User - Enabled -
    PK 704 - All Windows - User - Disabled -
    PK 15 - AlternateTab - System - Enabled - Favorite
    PK 6 - Applications Menu - System - Disabled -
    PK 16 - Auto Move Windows - System - Disabled -
    PK 779 - Clipboard Indicator - User - Enabled - Favorite
    PK 307 - Dash to Dock - User - Enabled - Favorite
    PK 884 - Disper Menu - User - Disabled -
    PK 7 - Removable Drive Menu - System - Disabled -
    PK 442 - Drop Down Terminal - User - Enabled -
    PK 885 - Dynamic Top Bar - User - Enabled - Favorite
    PK 810 - Hide App Icon - User - Enabled -
    PK 544 - HistoryManager Prefix Search - User - Enabled -
    PK 600 - Launch new instance - System - Disabled -
    PK 36 - Lock Keys - User - Enabled -
    PK 898 - MMOD Panel - User - Disabled -
    PK 18 - Native Window Placement - System - Disabled -
    PK 750 - OpenWeather - System - Enabled - Favorite
    PK 708 - Panel OSD - User - Enabled -
    PK 8 - Places Status Indicator - System - Disabled -
    PK 836 - Internet Radio - User - Disabled -
    PK 881 - Screenshot Window Sizer - System - Disabled -
    PK 9 - SystemMonitor - System - Disabled -
    PK 1052 - Taskwarrior Integration - User - Disabled -
    PK 570 - Todo.txt - User - Enabled - Favorite
    PK 1166 - Extension Update Notifier - User - Enabled -
    PK 19 - User Themes - System - Disabled -
    PK 549 - Web Search Dialog - User - Enabled -
    PK 602 - Window List - System - Disabled -
    PK 10 - windowNavigator - System - Disabled - Favorite
    PK 21 - Workspace Indicator - System - Disabled - Favorite

My script :
Code: Select all
#!/bin/bash

      input="status.fav"
      ni=0
      while IFS= read -r var
      do
        var=`sed 's/ - /-/g' <<< $var`
        IFS="-" read -a arr <<< $var
        #echo ${#arr[@]}
        IFS=" " read -a arr2 <<< ${arr[0]}
        #stri=${arr[0]}
        strpk1=${arr2[0]}
        strpk2=${arr2[1]}
        strname=${arr[1]}
        stred=${arr[2]}
        strusrsys=${arr[3]}
        strfav=${arr[4]}
        #echo $stri1 ; echo $stri2 ; echo $strj ; echo $strk ; echo $strl ; echo $strm ; echo "---"
        line='..........................................................................................'
        format="%-2s %4d %-80s %s %-10s %-10s %-10s\n"
        printf "$format" "$strpk1" "$strpk2" "$strname ${line:${#strname}}" "$stred" "$strusrsys" "$strfav"
        ni=$[ni+1]
        nf=`grep Favorite status | wc -l`
        ne=`grep Enabled status | wc -l`
        nd=`grep Disabled status | wc -l`
        nu=`grep User status | wc -l`
        ns=`grep System status | wc -l`
      done < "$input"
      echo "(Extensions installed : $ni - Favorites : $nf - Enabled : $ne - Disabled : $nd - User : $nu - System : $ns)"


Also printf is slower than echo

maybe use column?

see:

Code: Select all
man column


I think it is installed by default on Debian (it is in package bsdmainutils)

But I am not sure I understand what you want.

The output would like this
I tried with 'column' which seems fine but my output is too long
    column: line too long
    column: line too long
    column: line too long
    ...
My output, it is not well formatted on the end of the line
Numbers are aligned on right side
    PK 744 Hide Activities Button .................................................................... User Enabled
    PK 72 Recent Items .............................................................................. User Enabled
    PK 584 TaskBar ................................................................................... User Enabled
    PK 704 All Windows ............................................................................... User Disabled
    PK 15 AlternateTab .............................................................................. System Enabled Favorite
    PK 6 Applications Menu ......................................................................... System Disabled
    PK 16 Auto Move Windows ......................................................................... System Disabled
    PK 779 Clipboard Indicator ....................................................................... User Enabled Favorite
    PK 307 Dash to Dock .............................................................................. User Enabled Favorite
    PK 884 Disper Menu ............................................................................... User Disabled
    PK 7 Removable Drive Menu ...................................................................... System Disabled
    PK 442 Drop Down Terminal ........................................................................ User Enabled
    PK 885 Dynamic Top Bar ........................................................................... User Enabled Favorite
    PK 810 Hide App Icon ............................................................................. User Enabled
    PK 544 HistoryManager Prefix Search .............................................................. User Enabled
    PK 600 Launch new instance ....................................................................... System Disabled
    PK 36 Lock Keys ................................................................................. User Enabled
    PK 898 MMOD Panel ................................................................................ User Disabled
    PK 18 Native Window Placement ................................................................... System Disabled
    PK 750 OpenWeather ............................................................................... System Disabled Favorite
    PK 708 Panel OSD ................................................................................. User Enabled
    PK 8 Places Status Indicator ................................................................... System Disabled
    PK 836 Internet Radio ............................................................................ User Disabled
    PK 881 Screenshot Window Sizer ................................................................... System Disabled
    PK 9 SystemMonitor ............................................................................. System Disabled
    PK 1052 Taskwarrior Integration ................................................................... User Disabled
    PK 570 Todo.txt .................................................................................. User Enabled Favorite

Take note than in my input file when the hyphen finish the line, it is followed by a blank space
because the blank space can be replaced by 'Favorite'

Note :
I found the command 'pr' but i get no luck with it now
pr -s'-' -6 -e'-' -t | awk '{printf "%-3s %-5s %-80s %-10s %-10s %-10s\n", $strpk1, $strpk2, $strname, $stred, $strusrsys, $strfav}'
column is ok with files, not with variables
and can't enlarge the name field with dots

Column displays a well aligned text but it fills the half of the screen

printf allows me to work with variables on each line
i find this solution better

but to align the end of each line is is not the easy part

I have improved my script and added a column
Changed printf settings and it is near perfect
Except the last column
https://ibb.co/eCmmCk
Code: Select all
        format="\t%2s %5i %-75s %-10s %-8s %-10s %-10s\n"
        printf "$format" "$strpk1" "$strpk2" "$strname" "$stred" "$strusrsys" "$strfav" "$strsett "


I get it aligned if i remove the favorites
https://ibb.co/io7F55

Maybe i go with awk and change completely my function
so i can play with reverse video for the text or other settings

awk makes it perfect but the result is a text file, not variables to play with
Code: Select all
cat statusawk | awk -F "-" '{ printf("\t%- 2s % 5i  %- 75s  %- 10s %- 10s %- 10s %- 10s\n", $1, $2, $3, $4, $5, $6, $7, $8); }'

https://ibb.co/k4wsk5

i think i can do that :-)
I got new ideas

Solution with printf
It is misaligned because the variable is empty
I just fill it with one blank space and it rocks
But it is always slow, displaying one line by one
