在字符后获取字符串 [英] Get string after character

问题描述

我有一个看起来像这样的字符串:

I have a string that looks like this:

 GenFiltEff=7.092200e-01

使用 bash，我只想获取 = 字符后的数字.有没有办法做到这一点?

Using bash, I would like to just get the number after the = character. Is there a way to do this?

推荐答案

对于第一个 = 之后和下一个 =

For the text after the first = and before the next =

cut -d "=" -f2 <<< "$your_str"

或

sed -e 's#.*=()#1#' <<< "$your_str"

对于第一个 = 之后的所有文本，无论是否有多个 =

For all text after the first = regardless of if there are multiple =

cut -d "=" -f2- <<< "$your_str"
