Hi Gopal,

You modify your script xyz.sh to accept the first parameter $1 with port number. In the script the value of variable $1 is the one passed as parameter to xyz.sh from the prompt. If port number is static, you need not have this parameter rather you could hardcode it.

you can define cron job as

0 15 * * */home/abc/xyz.sh 5320 >/dev/null 2>&1

Thanks,
Srikanth

Hi Srinikant,

I can understand this. But suppose we can not update the scripts, in that case is it possible or not?

Thanks

hi,

Cron is more for non-interactive scripts! You cannot change its behaviour. Of course, you can run the script using the cron and which takes its input from a file.

e.g.
...
INPUT=$(cat /home/yogeeraj/mvar.txt)
if [ $INPUT = 'XYZ' ]; then
...

hope this helps!
kind regards

Hi Gopal,

you can do the following :

1. create a file abc and put the port no. into it

# cat 999 > /tmp/abc

2. now run xyz.sh and redirect input to /tmp/abc.

# ./xyz.sh < /tmp/abc

3. Now use the same in cron
10 10 * * * /path/xyz.sh < /path/abc

RD
