Export, clipboard copy and echo a token Bash one-liner

Here’s a handy Bash one-liner to generate a token or some other kind of command output, and do three things at once with it:

• Export it as an environment variable in the shell.
• Copy it to the clipboard.
• Echo it to the terminal.

export FOOBAR_TOKEN=$(foobar-token-command --foobar "foobar") \
    && echo -n $FOOBAR_TOKEN | tee >(xclip -selection clipboard)

I find this is handy for things like security tokens which I often want as an environment variable in the shell as well as being able to paste them into other tools such as HTTP testing apps.

It’s also nice as a quick example of how to use $() and >() in Bash.

Note the echo -n to echo the token without a trailing newline.
