As a non-native English speaker, I have difficulty remembering Linux commands compared to other

  • 0

As a non-native English speaker, I have difficulty remembering Linux commands compared to other APIs. In Linux, the function names don’t seem to indicate their purpose.

Why is the name fork() chosen to create a child process? In the dictionary, fork means “a utensil with two or more prongs”, which is unrelated to creating a new process.

Why is the name grep chosen to “print lines matching a pattern”? Does grep mean “g report”?

Where can I find the etymology behind other commands in the Linux API?

    Fork can mean to split in two, as a road (source).

    Fork (15): to divide into branches.

    Grep’s etymology:

    From an idiomatic command sequence in the qed and ed text editors: ‘g/re/p’, meaning: globally search for a regular expression and print.

    This answer lists the etymology of some Linux commands.
