怎么样用write给所有的用户留言

[hellojinjie]

我的代码是这样的

代码： 全选

for i in `who`;do write `awk '{print $1, $2}'` <<< hi; done

但这是错误的

居然。。。这么复杂。。。

代码： 全选

sudo -s
for i in `who|awk '{print $1$2}'|sed s/tty/_tty/`;do write `echo $i|awk -F '_' '{print $1,$2}'` <<<hello\! ;done

其实wall也蛮好用的。。。

[hellojinjie]

没有权限用 wall

你没有考虑pts的情况哦，就是用ssh登陆的时候不是tty

代码： 全选

who | awk '{print $1, $2}' | while read line; do write "$line" <<< hi ; done

可是输出还是错的。

代码： 全选

happy everyday ~$ who | awk '{print $1, $2}' | while read line; do write "$line" <<< hi ; done
