i want to trim an output of wipe command with sed. i try to use this one:
wipe -vx7 /dev/sdb 2>&1 | sed -u s/.* ([0-9]+).*/1/g
但出于某种原因,它没有工作。
当使用回合和amp时,它就能够印刷血压控制的产出!
echo "/dev/sdb: 10%" | sed -u s/.* ([0-9]+).*/1/g
什么是错的?
感谢!

示范:
$ cat foo
#!/bin/sh
echo hello > /dev/tty
$ a=$(./foo)
hello
$ echo $a
$ a=$(unbuffer ./foo)
$ echo $a
hello
