标题: uid to user name
want to get the user name from uid for example uid=1667

id -un 1667, it gives no such user, which 1667 is my account, any idea why? thanx

actually i need ps -ef to check if something is run by one user, and i need the username, eg, alex.g, but ps -ef gives the uid at the first column

我在solaris, redhat上试的ps -ef第一列都是username呀

你可以用ps -e -o "%U %a"，第一列是USER

ps -ef | awk '/$uid/{print $1}'

solaris下ps -e -o "user args"

如果ps出不来用户名的话可以去/etc/passwd文件找对应的用户名，你看看ps的man吧，应该是没有问题的。

man id

SYNOPSIS
id [OPTION]... [USERNAME]

so, the id command eats USERNAME only as it's argument, not the UID instead.
clear?
