Sometime duplicate executable files or alias creates tons of confusion. To find out duplicated executables files you can use chkdupexe command.
It will scan the union of $PATH and a hardcoded list of common locations for binaries. It will report dangling symlinks and duplicately-named binaries.
Examples
$ chkdupexe
Output:
Dangling symlink: /usr/bin/rmic Dangling symlink: /usr/bin/jar -rwxr-xr-x 1 root root 38936 Sep 23 2004 /usr/bin/nsupdate -rwxr-xr-x 1 root root 203960 Jan 26 2005 /usr/sbin/nsupdate -rwxr-xr-x 1 root root 15139 Apr 6 01:48 /sbin/grub-install -rwxr-xr-x 1 root root 6453 Apr 1 18:38 /usr/sbin/grub-install
As you see, it is quite easy to identify all those duplicates executables files. There is also some good discussion going on about PATH and aliases.

Excuse me, does ‘hkdupexe’ command exist in GNU/Linux? I doesn’t seem to find it.
Thanks
oh, sorry for my poor english, I mean: I don’t seem to find it.

Command name is chkdupexe and not hkdupexe. It was typo :(
Sorry, and post is updated for accuracy.
