As a pragmatic command-line user, I just found a new way to easily interact with the clipboard.
Yes, yes, I knew about 'xclip' before now -- but it was just way too hard to use because it made me type (and remember) lots of options for simple clipboard operations.
Introducing 'xcl', a simple, helpful wrapper around 'xclip':
This uses a little-known trick from bash (really from the 'test' or '[' builtin), which allows me to detect whether a file descriptor is attached to a live terminal.
Hope this is helpful to you.
