ulimit

[rajkumarmadhani]

I am successfully running "ulimit -c unlimited" from command prompt

But how to run it from shell script.

thanks in advance.

does this not work?

#!/bin/sh
ulimit -c unlimited

ulimit is a shell command and its results are lost when the shell exists, hence the difficulty using it in a shell script. You can use it in a script that is "sourced" from your current session with either the "source" of "." commands. Ie, "source setulimit.sh" where the "setulimit.sh" file looks like this:

ulimit -c unlimited

Sourcing it is just as if you typed it in.

Alternatively, you can put the ulimit command inside your ~/.bashrc so that it will always be active when you start a shell in your account.

yes, i assumed the value was only needed inside said script.

I placed it in /etc/profile and it is working now
thank you

Raj,
Now, you have my curiosity up.
From "man ulimit" I read the following :

ULIMIT(3) Linux Programmer's Manual ULIMIT(3)
NAME
ulimit - get and set user limits
SYNOPSIS
#include <ulimit.h>
long ulimit(int cmd, long newlimit);
DESCRIPTION
Warning: This routine is obsolete. Use getrlimit(2), setrlimit(2), and
sysconf(3) instead. For the shell command ulimit(), see bash(1).
The ulimit() call will get or set some limit for the calling process.
The cmd argument can have one of the following values.
UL_GETFSIZE
Return the limit on the size of a file, in units of 512 bytes.
UL_SETFSIZE
Set the limit on the size of a file.
Manual page ulimit(3) line 1/52 45%

What catches my eye is :
" Warning: This routine is obsolete. "

So, what is your interest in "ulimit" ?

Sorry, It just occurred to me that you are on an "older" system.
Probably Maintaining code.
