Obligatory example where the extra backslash makes a difference: $ printf '%s\n' 'asterisk: *' 'backslash: \' | grep '[*]'
asterisk: *
$ printf '%s\n' 'asterisk: *' 'backslash: \' | grep '[\*]'
asterisk: *
backslash: \
It depends on the regex flavour though (doesn't happen with Python, JavaScript, or Perl for example). |
