  • Batch resize images (overwriting)

    Requires ImageMagick to be installed; mogrify is the lesser-known sibling to convert -- it overwrites your original images, but allows you to work on batches of files without resorting to a loop.

  • Command to rename multiple file in one go

    An entirely shell-based solution (should work on any bourne-style shell), more portable on relying on the rename command, the exact nature of which varies from distro to distro.

    for f in ./*.xls; do mv "$f" "${f%.*}.ods"; done

  • Delete all empty lines from a file with vim

    Here's the other way of doing it in vim: setting a recursive macro. 'gg' brings you to the top of the buffer, 'qqq' clears the 'q' macro, 'qq' starts recording a macro called 'q', '/^$' moves the cursor to the next empty line, 'dd' deletes the line that the cursor is on, '@q' calls the 'q' macro (currently empty because of 'qqq'), and 'q' stops recording the macro. '@q' calls the macro. It will run until it cannot find another blank line, at which point it will throw up an error and cease. While this is longer than the regex, you can use it without having to move your thoughts from 'vim-mode' to 'regex-mode'.
