xargs這個命令感覺挺有用的
比如批次刪除redis 以某個字元作為開頭的條目。

刪除key以mvbox開頭的所有條目:

redis-cli keys "mvbox_*" | xargs redis-cli del

或者

[lihuilin@lihuilin ~]$ cat test.txt

1

2

3

4

5

[lihuilin@lihuilin ~]$ cat test.txt | xargs -i echo delete user where id={}

delete user where id=1

delete user where id=2

delete user where id=3

delete user where id=4

delete user where id=5

Linux xargs 命令
