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

Uhm... What happens when you run say
Code:

/bin/cat /etc/inittab
cheers

inTUXicated 08-06-2003 05:38 AM

/bin/cat /etc/inittab

-bash: /bin/cat: cannot execute binary file

jharris 08-06-2003 05:57 AM

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

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.

tnx
do u know where i can get a new copy of the cat binar? or is it available in the RH cd ??

jharris 08-06-2003 07:56 AM

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
