ls command not working 8

[northgrum]

On an IBM RS6000 F50 running AIX 4.3, I am getting the following error when using the "ls" and "ps" commands:
$ ls
sh: /usr/share/lpp/.index/old/ls: not found.
$ ps
sh: /usr/share/lpp/.index/old/ps: not found.

This just started happening and I cannot figure out why now certain commands aren't working.
Thanks for your help!

Holy Cow. Copying the ls file from another machine worked! It must have just been a corrupt file.
Man alive.
I would like to thank EVERYONE who posted here. I will mark you all as helpful users.
Thanks again.

hi,
the Agatha Christies post, has been discovered !

how suggested, reinstall bos.rte.commands or ML11 :
that was only a test, not a solution; as for ps, you can have other commands (in bin, corrupted)

Furthermore: assume a detective
