does it work if you specify the full path to the command?
ie:

Code:

 $ /bin/ls

If so, something has gone wrong with your path.

Code:

 $ echo $PATH

What does this show?

Check your .bashrc and .bash_profile as well as /etc/bashrc for the PATH variable.
It should go a little something like this (but possibly different)

Code:

/usr/local/sbin:/sbin:/bin:/usr/sbin:/usr/bin:~/bin/:/usr/local/bin:/usr/local/sbin:/usr/local/usr/bin/:/root/bin

In addition, how about giving us some details? Just saying "It doesn't work" doesn't do much good when you're trying to determine what the problem is.

What distribution are you using?
What shell are you using?
What terminal or terminal emulator are you using?
When did the problem start?
What did you do just before it started?
What have you tried so far to diagnose/remedy it?
Does it continue after restarting the shell, desktop, or system?
What other possibly relevant details can you give us?

I am using centos5.5, using bash shell. I can't login in GUI its showing an error
"Your session only lasted less than 10 sec" /etc/gdm/Presession/Default:Registering your session with u tmp........(~/.xsession-errors file).

When I login in CLI(ctrl+alt+f1) as root shows one message like
Sh:gzip:command not found
Bad character height 0

The result of echo $PATH is /usr/lib/qt-3.3/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/root/bin
So I have to export PATH=$PATH:/bin:/usr/local/bin

I checked the files .bashrc ,.bash_profile and /etc/bashrc , there is no changes.
