Two lines I added to my .bashrc today:
alias xargs0='xargs -0'
function find0 { find $@ -print0; }
-print0 on find and -0 on xargs aren’t usually important on your typical unix setup, but on a Mac you have spaces everywhere in file names, so these options are used too often to go without conveniences for them.
I can’t believe I didn’t create these aliases before today.
