How do I use the output of a command as a parameter in another command? My specific example is that I want to get the PID of a process using
pgrep and pass it to the
-p option of
I've tried things like the following:
pgrep myprocess | lsof -p /dev/stdin
pgrep myprocess | lsof -p -
I know you can do it like this:
pid=$(pgrep myprocess) && lsof -p "$pid"
But there has to be a better way to do it. Perhaps
xargs or something? I haven't been able to find something clean, so I'd appreciate any help.
