The wait command is typically used in shell scripts that spawn child processes that execute in parallel. To illustrate how the command works, let’s create the following script: #!/bin/bashsleep30&process_id=$!echo"PID:$process_id"wait$process_idecho"Exit status:$?" ...
wait is a command that waits for the given jobs to complete and returns the exit status of the waited for command.
How to use the “for” loop in the shell script? What is the difference between for loop and for loop in Bash? What is a one-line for loop in Bash? How many times does a for loop run in Bash? How to iterate on multiple lines in a for loop in bash?
