Getting location of the script which is currently being executed

jiju.jacob · 07-21-2008, 03:24 AM

Hi,

I have a shell script named a.sh inside /home/root directory and I have to run this script from the /tmp directory.

I issue the command as

linux-7vps: /tmp # ./home/root/a.sh

Now inside a.sh, I would like to get the path where this script a.sh resides without opting for a search.

Can I get the location of the script ?

Please let me know how to do it ?

Linux Flavor : RHEL 4/ RHEL 5

Thanks in Advance,
Jiju

pwd would be a command.
But what is /home/root ?

maybe it would help to know what the script finaly should do at all?

/home/root is the home directory for the root user.
This tiny script is intended to be a part of larger script. The function of the tiny script is to write the directory name on which resides to a file as soon as it is executed. Another Process will then read the path of the script from this file and use it for other purposes.

You can try either

Code:

dirname `which $0`

or

Code:

readlink -f $0
