Which command is used to copy all files having the string chap and any two characters after that to the progs directory ?
Correct answer: A. cp chap?? progs
- A. cp chap?? progs
- B. cp chap* progs
- C. cp chap[12] /progs/*.*
- D. cp chap?? /progs/*
Explanation
The `?` wildcard matches exactly one character, so `chap??` selects filenames beginning with `chap` followed by exactly two characters. The `cp` command then copies those matches into the `progs` directory.
