What OS are you using? On Sun, you can use ptree <pid of current shell>.

Try this script:

Code:

#!/bin/ksh

if [ $# -ne 1 ]; then
        echo "usage: proc_tree.sh <pid>"
        exit -1
fi
pid=$1
while [ $pid -ne 1 ]; do
        ps -ef | nawk -v awkpid=$pid '{if($2==awkpid) print }'
        pid=$(ps -ef | nawk -v awkpid=$pid '{if($2==awkpid) print $3}')
done

This will print parent processes all the way to init.
