list files in 'hitlar' mode

Was playing with the shell. It struck to me, just by rearranging the parameters, i was able to remember what they did and in a cool way. Enter the 'hitlar' mode. bash-3.2$ ls -hitlar Shows all items with inodes, in list view, human readable size, sorted by modification time in reverse, bash-3.2$ ls -Fhitlar Shows the same with classification info. Add the hitlar mode alias to your .bashrc. bash-3.2$ echo "alias hitlar='ls -Fhitlar'" >> ~/.bashrc bash-3.2$ hitlar bash-3.2$ hitlar filename

shell function to make gnu info act like man.

I use this alias in my bashrc. The --vi-keys option makes info use vi-like and less-like key bindings.

This is great for looking for files that have been updated recently. Logs especially or monitoring what files were added during an install.
