Question

Apols但确定有人可以提供这个正则表达式只是不与我一起计算。

如果我想要匹配LABEL的UUID部分=＆＃34; Usb3Ext＆＃34;

，那么说如果我从blkid得到这个输出

/dev/sda1: UUID="f2134523-0628-f8bd-359d-4f19069e2b6e" UUID_SUB="3e97c008-8038-bca2-5073-bfedb2e24ee8" LABEL="portal:1" TYPE="linux_raid_member" PARTUUID="e52e2353-01"

非常感谢

Answer 1

您可以像这样使用awk：

blkid | awk '/LABEL="Usb3Ext"/{i=gensub(/.* UUID="(.*)".*/, "\\1", "g");print i}'

或sed：

blkid | sed '/LABEL="WINRE_DRV"/!d;s/.* UUID="\(.*\)".*/\1/'

最好使用lsblk：

lsblk -no LABEL,UUID | awk '$1 == "Usb3Ext" {print $2}'

Answer 2

不太优雅，但它有效（不过UUID出现的地方）：

blkid | awk -F'UUID = \“''{print $ 2}'| awk -F”\“”'{print $ 1}'

正则表达式列出blkid标签
