示例字符串 :
/气喘/字符串
预期结果: string
要删除的字符 : "/" 符号之间的所有字符,包括符号
sed :
$ echo "/gasg/string" | sed -e s//.*///g
string
使用内置制的制片组字符串操作 :
$ s="/gag/string"
$ echo "${s##/*/}"
string
您的字符串看起来完全像 Unix 路径名。 这就是为什么您也可以使用 basename 工具 - 它返回给定 Unix 路径名的最后一部分 :
$ basename "/gag/string"
string
# It works with relative paths and spaces too:
$ basename "gag/fas das/string bla bla"
string bla bla
还有 awk - 使用斜线作为分隔符并打印上一个字段
echo "/gas/string" | awk -F/ {print $NF}
或剪切 - 但只有在您有相同数量的目录可以脱去时, 这才有效 。
echo "/gasg/string" |cut -d/ -f 3
您可以使用bash 字符串操作
a= /gasg/string
echo ${a##*/}
