Find duplicate executables files

by on May 16, 2006 · 3 comments· LAST UPDATED May 17, 2006


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.


$ chkdupexe


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.

Command name is chkdupexe and not hkdupexe. It was typo :(

Sorry, and post is updated for accuracy.
