Dear UNIX Diary,

Today I discovered the true power of a xargs. Maybe not "the true power" per se, but the first time I'd find a use for it. Close enough. hsetroot can change the wallpaper for me and meh can output the viewed file's name to standard output. You catch where I'm going with this?

Just a simple hackjob in my ~/.mkshrc...

Code:
export WALLPATH=$HOME/img/wall

...

setwall()    {

    meh $WALLPATH/* 2>/dev/null |xargs -I% hsetroot -center %

}

Boom. Interactive wallpaper changer with preview. I'll be expecting to use xargs more somewhere.
