bash: /bin/cat: cannot execute binary file


i can't seem to view files like inittab when i'm using a terminal.for example when i enter:

cat inittab

i get :

bash: /bin/cat: cannot execute binary file

is there any program that i need to install for me to make this command work again?

Whats the output of
Code:
ls -l /bin/cat
and
Code:
mount
I expect either the permissions are set incorrectly on cat or the filesystem on which is resides is mounted with noexec.

cheers

What happens when you
Code:
more /etc/iniitab
Do you get the same error? The size of you cat binary looks good but there's always the chance it's corrupt or invalid somehow - what does
Code:
file /bin/cat
show you?

cheers

more /etc/inittab

# inittab This file describes how the INIT process should set up

# Default runlevel. The runlevels used by RHS are:

# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 - Full multiuser mode
# 4 - unused

Looks like your version of cat is corrupt then. What you should have seen from the "file" command was
Code:
jh@e128 jh]$ file /bin/cat
/bin/cat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared libs), stripped
You'll need to get a new copy of the cat binary, although I'd be a little concerned about what damaged it in the first place.

cheers

It'll be in one of the RPMs on the CD but I'm not sure which one off the top of my head as I'm not much of a RH guy myself. If you mail me I'll send you a copy from my RH9 box here at work if you wish.

cheers
