location path...

nilathinesh · 07-18-2007, 09:21 PM

hi,

i am newbie... and i am in a need of help in writing BASH script, in which i need to get the current file location path of the script file inside the script file itself.

ie.,

/home/thinesh/desktop/myscript.sh -> inside this script i need to get the location path of the myscript.sh as "/home/thinesh/desktop"
if same script is copied into /home/thinesh/assignment/myscript.sh, and executed there.. then it has to show the path as "/home/thinesh/assignment/".. and if i invoke the myscript.sh from some other directory as "/Lindows/project$ /home/thinesh/assignment/myscript.sh" there also it has to say the path as /home/thinesh/assignment

thanks...

regards,
thinesh

Hint. What do the following commands return:

Code:

$ echo $CWD

and

Code:

$ pwd

so

Code:

#!/bin/sh

CURRENT_PATH_LOCATION=`pwd`
echo $CURRENT_PATH_LOCATION

thanks bsdunix..

.. but the "pwd" will return only the present working directory and not the directory where the
script file resides..
also i do not find the command CWD... !?,

sorry..if my explanation... creates confusion..

Sorry, I must have been thinking of another un*x.

Your original post said:

Maybe if you post your script and identify where it's failing, we (or at least me) can get a better idea of what you want.

ok..let me explain.. another way...

i am now in the directory

/home/thinesh/desktop

myscript.sh is there.

i have written code as

Code:

.
.
export ASSIGN1_PATH=`pwd`/methods
.
.

so when i invoke this myscript.h from current directory, then
my assign1_path will be like "ASSIGN1_PATH=/home/thinesh/desktop/methods"

1). now.. if i switch to directory /Lindows/Project
and from their i invoke the script as

"[thinesh@localhost Project]$ /home/thinesh/desktop/myscript.sh",

after that....assign1_path is setting as "ASSIGN1_PATH=/Lindows/Project/methods" and not the one i want as "ASSIGN1_PATH=/home/thinesh/desktop/methods"

2). then... if i copy my myscript.sh to someother folder like /work/script/ and i switching to folder /Lindows/methods/ and if invoke the script as

"[thinesh@localhost methods]$ /work/script/myscript.sh"
then i need to get the assign1_path as "ASSIGN1_PATH=/work/script/methods"

sorry.. if it is not clear...

May not be elegant, but what comes to mind is:

Code:

#!/bin/sh

MYSCRIPT_LOC=`find / | grep myscript.sh | sed s/\/myscript.sh//`
echo $MYSCRIPT_LOC

so if myscript.sh is located at /var/tmp/myscript.sh, the above should output /var/tmp.

Is this what your looking for?
