      Hi

I have a linux box which has CentOS running in it. I logged into the box 
using root and wrote a script in the /home/proc_threads directory. saved 
the file and quit. I changed the file permissions such that any user 
could execute it using the "chmod 777 filename" command.

When i log out and log in as a non-root user i was not able to execute 
the script though.

Could some one please help in this regard. I am a newbie to linux.

Thanks
Jatin

Hi,

have another users access to /home/proc_threads directory? :) Don't you
call any functions from script which can be executed only by root..?

Send us the exact error which you get after execute your script as an
user.. If it is a bash script, you can debug it with "-x" option..

Excuse my english :)

Here is the script that i am trying to execute as a non-root user:

#!/bin/sh

ps -C java -o thcount > /home/proc_threads/tempfile

awk ' { total += $1 } END { print total } ' /home/proc_threads/tempfile

here is the output when i try to execute as a non-root user:

./javathreads: line 2: /home/proc_threads/tempfile: Permission denied

awk: cmd. line:1: fatal: cannot open file `/home/proc_threads/tempfile'
for reading (Permission denied)

Thanks

Jatin

...and what are permissions of /home/proc_threads/tempfile? It seems,
that users can't write to it.. Try 'chmod o+w
/home/proc_threads/tempfile'
