Wait for each specified process to complete and return its termination status.
Syntax
wait [n ...]
Key
n A process ID or a job specification
Each n can be a process ID or a job specification; if a job specification is given, all processes in that job's pipeline are waited for.
If n is not given, all currently active child processes are waited for, and the return status is zero.
If n specifies a non-existent process or job, the return status is 127. Otherwise, the return status is the exit status of the last process or job waited for.
This is a BASH shell builtin, to display your local syntax from the bash prompt type: help wait
Example
$ wait 2585
