Unix `cp` command with $ sign -



Unix `cp` command with $ sign -

this question regarding unix cp command.

what $(...) operator doing below?

cp $(bundle show bootstrap-sass)/vendor/assets/stylesheets/bootstrap.scss \ app/assets/stylesheets/bootstrap-custom.scss

i came across notation page: https://github.com/twbs/bootstrap-sass#usage

i checked man page cp , did not see references operation. i'm new *nix. thanks.

in shell scripting, $(...) executes commands in parenthesis , returns text printed stdout command. applies backtick notation well.

for example: echo $(date) - dated line print thu jun 26 10:08:20 cdt 2014 - dated line

here's stack overflow question on topic.
