I would like a shell script like this
my-app & echo $my-app-pid
But i do not know how the get the pid of the just executed command.
I know I can just use the
jobs -p my-app command to grep the pid. If i want to execute the shell multiple times this method will not work Because the jobspec is ambiguous.
The PID of the last executed command is in the
$! shell variable.
my-app & echo $!
