# The `Wait` commands
It is a command that waits for completing any running process of given id. if the process id is not given then it waits for all current child processes to complete.

Create a file named "wait_example.sh" and add the following script to it.
```
#!/bin/bash
echo "Wait command" &
process_id=$!
wait $process_id
echo "Exited with status $?"
```
**Step-2**:
Run the file with bash command.
```
$ bash wait_example.sh
```
