I hate `echo X | Y`

base64 -d <<< aHR0cDovL3d3dy50d2l0dGVyc2hlZXAuY29tL3Jlc3VsdHMucGhwP3U9Y29tbWFuZGxpbmVmdQo=
apart from not being generalisable to all shells, `Y <<< X` seems nicer to me than `echo X | Y`, e.g. &lt;&lt;&lt; lol cat; it reads easier, you type less, and it also looks cool

It seems that every day I learn a new operator in bash. I'm not sure if this is a good or bad thing, but it delights me every time! Thanks for this!

I tested it on my Fedora system: Works with bash, mksh, and zsh, does not work with csh and tcsh.

if you care about keystrokes put alias e=echo in your .bashrc while you're at it pop alias en='echo -n' in there too doesn't work for in='

Doesn't work in bash-invoked-as-sh, so it's something you need to remember doesn't work in #!/bin/sh scripts... doesn't work in dash either (basically, "not in POSIX at all")
