Shell Programming and Scripting

Hi, my question is similar to my earlier post from 2009 which is Closed now
https://www.unix.com/shell-programmin...ript-name.html

script child.sh can be called by any script say, parent1.sh, parent2.sh, parent3.sh,...
child.sh should be able to say what's it's parent script command line

child.sh

Code:

echo "My command line is $0 $@"
echo "My parent command line is $(cat /proc/$PPID/cmdline)"

parent1.sh

Code:

child.sh c1 c2

If i run this command:
parent1.sh p1 p2 p3

i should see the result:
My command line is child.sh c1 c2
My parent command line is parent1.sh p1 p2 p3

I took the 'cat /proc/$PPID/cmdline' line from 'frans' reply in the Closed thread

However /proc directory is not available
Our is HP-UX 11.11 box, where can i find the file that stored the cmdline information by process id?

Thanks,

As a work around you can make use of this:

Code:

pandeeswaran@ubuntu:~/training$ sh parent1.sh p1 p2 p3
My parent process is sh parent1.sh p1 p2 p3
pandeeswaran@ubuntu:~/training$ cat child.sh
pp=`ps -ef|grep $PPID|head -1|awk '{for (i=8; i<=NF; i++) print $i}'`
echo  "My parent process is "${pp}""
