I'm on Ubuntu: $ uname -a Linux nile 5.15.0-118-generic #128-Ubuntu SMP Fri Jul 5 09:28:59 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux
I can't seem to get grep to match lines with ] in them when using [ ] expression. grep only matches two characters string "\]" instead: $ echo ']' | grep -E "[\]]" # supposed to return ] but doesn't $ echo '\]' | grep -E "[\]]" # incorrectly matches '\]' but not ']' \] Possible grep bug: grep doesn't seem to correctly handle escaped "\]" inside [ ] expressions. Thank you, Khoa
