Tired of systemd improperly waiting for certain conditions to be met? Use waitfor for all of your conditional waiting needs.

waitfor is a command line tool that blocks until all specified conditions are met. It uses options to convey conditions and to configure certain options.

Requires: Python 3.4 or higher, patience

Options:

--check-time <amount>

Sets the amount of time the program should wait before performing each condition check, applies to all conditions.

--and

Sets the condition that should be met for each condition after it. In this case, every condition after it must be true in order for it to exit.

--nand

Sets the condition that should be met for each condition after it. In this case, every condition after it must be false in order for it to exit.

--directory-available <path>

Sets a condition that returns True if the directory specified is a directory or exists.

Example

waitfor --directory-available /home/foo --nand --directory-available /home/bar --check-time 20

Check every 20 seconds to see if /home/foo exists and /home/bar does not exist, exit when these conditions are met.
