top -p $(pidof <process_name>)
pidof <process_name> return one id
top command works. But if
pidof <process_name> more than one ids
top command does not work.
pidof returns ids with one space between them like :
123 124 125
If I can get these ids with comma like
123, 124, 125
top command will work. How can I change output format of
awk was used for formatting text data. But I can not find how can I use
awk for result of shell command.
