Don't think you can do it with just one bash expansion statement (unless they can be nested somehow), works fine with two though
$ start=${file%%\?*}; echo ${start##*.}
css
Вопрос
hey guys I'm wondering if there is a smart way to look back before a period in bash
file='foo'/bar/styles.css?ver=1.4.2
ext=$(echo ${file} | gawk -F "?" '{print$1}')
echo "${ext##*.}" # css
Seems like I should be able to do this all in my expansion somehow?
