Simple rust application to wait until a given file exists. By utilizing inotify, waitforfile does not use polling.
waitforfile <filename>
where filename is a relative or absolute path. If filename is an absolute path (e.g. /foo/bar/baz), the directory portion (e.g. /foo/bar) must already exist prior to running the command.
waitforfile will return with exit code 0 if the file already exists or has been created during
execution. If the directory is deleted while waitforfile is running, it will return with exit code
1.
Arch Linux: A package is available on the AUR.
Void Linux:
xbps-install -S waitforfile
For all other distributions, you may either download a binary release, or build from source. To install from source, you need to have cargo installed. Then, clone this repository and run:
