It will almost always be in /bin in any Unix or Unix-like system, because it's one of the fundamental utilities that may be vital in fixing the system when it's booted in single-user mode and /usr may not be available. Also, the Filesystem Hierarchy Standard *requires* it to be in /bin. Having said that, nothing requires it not to be elsewhere *as well*, and in Ubuntu and other Linux systems it is in /usr/bin too. And because PATH for non-root users will usually contain /usr/bin before /bin (or indeed may not contain /bin at all), 'command -v rm' or 'which rm' will usually list the version of rm that is in /usr/bin. e.g. on Amazon Linux: $ which rm /usr/bin/rm $ sudo which rm /bin/rm -- https://mail.python.org/mailman/listinfo/python-list
