There are certain standards that suggest where to look. For example, there's the Linux Filesystem Hiearchy Standard 3.0: https://refspecs.linuxfoundation.org/FHS_3.0/fhs/ch03s04.html In short, you want to hard code /bin for a command like rm. And yes it will always be in /bin on any standard Linux OS. Despite modern distros making /bin and /usr/bin the same directory, if the target OS is anywhere close to the standard, you can always find the basic commands in /bin. I would not hard code any script to use /usr/bin for any basic commands and I would not use anything other than /bin/sh or /bin/bash as the shell script shebang if you want any sort of portability. -- https://mail.python.org/mailman/listinfo/python-list
