You don't have to call 'test this' all the time, any sane shell should have lots of operators built in. [ -d "~/.recyclebin" ] || mkdir "~/.recyclebin" sort of thing. See test operators for a table of them. A few of them might be peculiar to BASH, most'll work anywhere.

You can also use the -p option to mkdir to simplify that more. If the directory already exists it does nothing.

Code:
#!/bin/sh

mkdir -p ~/.recyclebin && mv "$1" ~/.recyclebin
