getpwuid(p1 = v1) public

Returns the /etc/passwd information for the user with the given integer uid.

The information is returned as a Passwd struct.

If uid is omitted, the value from Passwd[:uid] is returned instead.

See the unix manpage for getpwuid(3) for more detail.

Example:

Etc.getpwuid(0)
#=> #<struct Etc::Passwd name="root", passwd="x", uid=0, gid=0, gecos="root",dir="/root", shell="/bin/bash">
