I wonder if anyone can help.
I found a command that fixed my problem but I can't find it again.
It is rather like that song The Lost Chord.
I am configuring a debian system on a Raspberry PI. It is a specail one for the Openmediavault.
It wouldn't connect to the wifi and I was investigating and googling and I found a command that i thought investigated the wlan but it fixed the problem.
I was investigating the startup messages appear on the screen and was getting No DHCPFFERS.
The command produced a series of lines very similar to that it the startup messages something like
DHCPSOMETHING ,,,,,,,,
but without the no offers stuff
so I tried a ping and discovered it was working
The command MIGHT have started with an if
Can anyone guide me as to what it was?

Re: Forgoted command help
The commandline has got a history. You can scroll it by opening a terminal and look at earlier commands by using the "arrow"-key of your keyboard.
The history is stored in the file:
~/.bash_history
(in this case probably the home directory of the root user, /root/.bash_history)
If you have edited /etc/inputrc (or if it is already edited in raspian) *and* you know the beginning of the command (you say "if"), you can type the beginning chars and use and the "page-up"-key.
You should edit /etc/inputrc to get that feature, it is very useful
uncomment these lines:
# alternate mappings for "page up" and "page down" to search the history
"\e[5~": history-search-backward
"\e[6~": history-search-forward
There is also the "apropos" command, perhaps it will help you:
apropos dhcp

Re: Forgoted command help
OpenMedia Vault might be “based” on Debian, but it is NOT Debian.
Look at viewtopic.php?f=3&t=114644&start=15#p542283
You would be better to ask the OpenMediaVault Forums >>> http://forums.openmediavault.org/index. ... 148736d371

You can answer your own question. As root, type "if" and use [TAB] completion to see the list of available commends that start with "if".cymro wrote:The command MIGHT have started with an if
