perl one liner + how to replace any last IP address octets You're passing stdin and also specifying a file name that probably doesn't exist (Do you have a file named "1.1.1.1"?) -- I get echo 1.1.1.1 | perl -pe 's/(\d+\.){3}\K\d+/0/g' ->
1.1.1.0 -- this is perl v5.16.3, I'm not sure when \K was introduced. |

Shell: How do I get the last argument the previous command when it was detached? It makes me chuckle when 3 characters is too much typing. As soon as the previous command has more than 3 arguments, I win!!!1! :) |

Using sed, how to format one word per line, removing white space @don_crissti, leading spaces are actually removed, but awk treats the empty string before the whitespace as an empty record. I've updated to only print non-empty records |

Using sed, how to format one word per line, removing white space This might be more secure: while read -ra words; do (( ${#words[@]} )) && printf "%s\n" "${words[@]}"; done < file |

Prompt user for sentence and store it without being disturbed by spaces Pity you're using an older version of bash. bash 4 has associative arrays which would make things much neater. |
