[英]Get the last string using a character as a delimiter in bash
Right now I have this: 现在我有这个:
echo "silly/horse/fox" | cut -d "/" -f3
fox
But I want to be able to get the last string no matter how many delimiters we have. 但是无论我们有多少分隔符,我都希望能够得到最后一个字符串。
So something like "silly/horse/fox/lion" would return me "lion" 所以像“傻/马/狐狸/狮子”这样的东西会让我“狮子”
Something of an equivalent to Python's string.split('/')[-1] 类似Python的string.split('/')[ - 1]
Pure bash
solution: 纯粹的
bash
解决方案:
$ foo="silly/horse/fox"
$ echo ${foo##*/}
fox
$ foo="silly/horse/fox/lion"
$ echo ${foo##*/}
lion
Using sed
: 使用
sed
:
$ echo "silly/horse/fox/lion" | sed 's#.*/##'
lion
awk
to the rescue: awk
救援:
$ echo "silly/horse/fox" | awk -F"/" '{print $NF}'
fox
$ echo "silly/horse/fox/but/not/that/much" | awk -F"/" '{print $NF}'
much
$ echo "unicorn" | awk -F"/" '{print $NF}'
unicorn
As $NF
refers to the last field. 因为
$NF
指的是最后一个字段。
awk -F'/' '$0=$NF'
or 要么
grep -o "[^/]*$"
or 要么
sed 's#.*/##'
