Check the process before run or not
Dear all,

Not very clear on what you want to achieve. But for an accurate java listing from the ps list, you should use

Code:
ps -ef | grep '[j]ava'

Thank you for all, this script works.

Code:
#!/bin/sh

if [ "$(ps -ef | grep "FileCollector.jar -id7" | wc -l)" -gt 1 ]; then
    # process is running
    echo "process is running"
else
    # process is not running
    echo "process is not running"
fi
