以下是此函数的简单语法 -

endpwent

返回值

此函数不返回任何值。

示例

以下是显示其基本用法的示例代码 -

#!/usr/bin/perl

while(($name, $passwd, $uid, $gid, $quota,
   $comment, $gcos, $dir, $shell) = getpwent()) {
   print "Name = $name\n";
   print "Password = $passwd\n";
   print "UID = $uid\n";
   print "GID = $gid\n";
   print "Quota = $quota\n";
   print "Comment = $comment\n";
   print "Gcos = $gcos\n";
   print "HOME DIR = $dir\n";
   print "Shell = $shell\n";
}

setpwent() ; # Rewind the databse /etc/passwd

while(($name, $passwd, $uid, $gid, $quota,
   $comment, $gcos, $dir, $shell) = getpwent()) {
   print "Name = $name\n";
   print "Password = $passwd\n";
   print "UID = $uid\n";
   print "GID = $gid\n";
   print "Quota = $quota\n";
   print "Comment = $comment\n";
   print "Gcos = $gcos\n";
   print "HOME DIR = $dir\n";
   print "Shell = $shell\n";
}

endpwent(); # Closes the database;
