I find that some commands, for example, ls
and pwd
, can be used on both Linux and Unix systems.
- Is it that all Linux commands can be used in the Unix systems, and all Unix commands can be used in Linux?
- Or just that all the Linux commands can run on Unix but not all Unix commands can run on Linux.
- Or that all Unix commands can run on Linux, but not all Linux commands can run on Unix?
- Or is there a reference to show me which commands can run on both Linux and Unix, and where both have their own unique command?
