How to fix the "whereis" command

English Install/Boot/Login
#1

Before today when I were going to type in console the command whereis (and for example) fire then pressing [TAB] will complete the word to firefox, if I were going to type ama [TAB] that will be completed to amarok or I was presented with all the options beginning with “ama”

Now when I press tab the word after the command whereis is not completed anymore.

Do you know what can I do to fix the feature/command ?

The only change I have performed lattely is that I resized my home partition (I increased its size) and I also installed firefox 3.0.1

What could have caused this ? and how can I fix this ? :eek:

It’s simply that whereis was not programmed as one of the commands that take command completion. These are specified to bash when it starts up, in

/etc/profile.d/complete.bash

If you do:

complete | grep which

you should get:

complete -o default -c which

Now whereis behaves like which in taking a command also. Search in /etc/profile.d/bash.completion and find the instance of which, which is:

complete -A command ${_def}             command which nohup exec nice eval

Add whereis to that list. Or you can test it from the current shell by:

complete -o default -c whereis

after which you can do:

whereis fire<tab>

BTW I knew about programmable completion but your post spurred me to learn something new today.

PS: Make a note of this local change, so that you put it back after a version upgrade.

PPS: Here’s a nice tute I found:

CLI magic: programable bash completion » Linux by Examples

The problem is I dont have that file callled “bash.completion”

Should I create it and add the line you suggested ?

This is all what I have inside there:

It’s complete.bash, the first instance I mentioned it I got the name correct, but I got it wrong on the second instance.

#5

Forget it… I found it!

The correct filename is:

/etc/profile.d/complete.bash

not:

/etc/profile.d/bash.completion
