关于cygwin出现用户问题

Win跟换了用户登陆使用cywin报告如下错误：

cygwin提示自己所在的组变成了”mkpaswd”, 这说明/etc/passwd或者/etc/group需要重建了。

Your group is currently "mkgroup".  This indicates that neither
your gid nor your pgsid (primary group associated with your SID)
is in /etc/group.

The /etc/group (and possibly /etc/passwd) files should be rebuilt.
See the man pages for mkpasswd and mkgroup then, for example, run

mkpasswd -l [-d] > /etc/passwd
mkgroup  -l [-d] > /etc/group

Note that the -d switch is necessary for domain users.

原因是新的登陆用户信息不在/etc/passwd和/etc/group中导致的：

运行mkpasswd -l >/etc/passwd; mkgroup -l >/etc/group即可修复。
