Python uses PWD and GRP to manipulate UNIX users and user groups

1. PWD Module

The PWD module provides an operating interface for the UNIX password database,/etc/passwd, which contains local machine user account information

Common operations are as follows:

Pwd.getpwuid (UID): Returns sample information for the corresponding UID

Example:

>>> pwd.getpwuid (0)       pwd.struct_passwd (pw_name='root', pw_passwd ='x', Pw_uid=0, pw_gid=0, pw_gecos='root', pw_dir='  /root', pw_shell='/bin/bash')

Pwd.getpwnam (name): Returns user information corresponding to name

Example:

>>> Pwd.getpwnam ('root') pwd.struct_passwd (pw_name='  Root', pw_passwd='x', Pw_uid=0, pw_gid=0, pw_gecos='root  ', pw_dir='/root', pw_shell='/bin/bash ')

Pwd.getpwall (): Returns all user information

Example:

Import pwd def get_user ()     = {}    for in  pwd.getpwall ()        = all_user[user[2]] = user     return All_user def userinfo (UID):     return get_user () [UID]

Execution Result:

Printuserinfo (0) pwd.struct_passwd (pw_name='Root', pw_passwd='x', Pw_uid=0, Pw_gid=0, pw_gecos='Root', pw_dir='/root', pw_shell='/bin/bash')PrintUserInfo'Root') pwd.struct_passwd (Pw_name='Root', pw_passwd='x', Pw_uid=0, Pw_gid=0, pw_gecos='Root', pw_dir='/root', pw_shell='/bin/bash')

2. GRP Module

The GRP module provides an interface for manipulating UNIX user groups, i.e., the/etc/group database.

Common operations are as follows:

Grp.getgrgid (GID): Returns the group information corresponding to the GID

Example:

Print grp.getgrgid (0) grp.struct_group (gr_name='root', gr_passwd='x  ', Gr_gid=0, gr_mem=[])

Grp.getgrnam (name): Returns the group information corresponding to name

Example:

print Grp.getgrnam ('root') grp.struct_group (gr_name='  Root', gr_passwd='x', Gr_gid=0, gr_mem=[])

Grp.getgrall (): Returns all group information
