背景:想用户登录ssh到linux时发邮件里有top,但发现出现top: failed tty get 错误 。
通过其他程序或脚本在非交互式模式下调用top命令,经常会出现:
top: failed tty get 错误
解决办法:加个-b 选项皆可
-b : Batch mode operation
Starts top in Batch mode, which could be useful for sending output from top to other programs or to a file. In this mode, top will not accept input and runs until the iterations limit youve set with the -n command-line option or until killed.
例如执行:top -bn 1
