Shell Programming and Scripting

Hi,

i have script called script.ksh

script.ksh
---------

Code:

echo "Narayana" >$HOME/script.log
echo "$0" |sed 's/.ksh//' >>$HOME/script.log

My question is:
--------------
when iam executing on the prompt it is giving good results what we have expected...

example on the prompt:
-----------------------

Code:

 
sh -x script.ksh

output:

Code:

Narayana
script

example scheduling in cron:
--------------------------

Code:

* * * * * sh -x $HOME/Narayana/script.ksh 2> /tmp/script_cron.log >&2

output:

Code:

Narayana
/apps/t1twsat/Narayana/script

So, could you please tell me... why this happened... any clue to overcome this...

Thanks in advance

You assume that cron will nicely cd to the directory where your script is?

The script will run from your home directory, and is run as specified in your crontab.

i.e.

Code:

$HOME/Narayana/script.ksh

$0 is the path to the script.

Code:

echo "Narayana" >$HOME/script.log
echo ${0##*/} >>$HOME/script.log

Another option is to do the cd in your cron definition:

Code:

* * * * * cd $HOME/Narayana; sh -x script.ksh 2> /tmp/script_cron.log >&2

Another comment, why are you giving your script the ".ksh" extension but executing it with a different shell, /bin/sh ?

scottn :thanks a lot...

jlliagre: thanks... but i have just written as example

I just wanted you to understand the "#!/bin/ksh" line was useless in both of your calls. You can use

Code:

ksh -x script.ksh ...

instead.
