    CLI tip 6: filtering lines based on multiple conditions
    1
    1. pyxelr 27 Feb 2022
      # line containing 'cake' but not 'at' # same as: grep 'cake' table.txt | grep -v 'at' # with PCRE: grep -P '^(?!.*at).*cake' table.txt $ awk '/cake/ && !/at/' table.txt blue cake mug shirt -7

      It should be easier to use awk over bash, especiallly for AND conditions.

      For example, for "line containing cake but not at": * grep: grep 'cake' table.txt | grep -v 'at' * grep with PCRE: grep -P '^(?!.*at).*cake' table.txt * awk: awk '/cake/ && !/at/' table.txt

      awk grep Bash
