目的

/etc/skel/目錄是用來存放新使用者配置檔案的目錄，當新增新使用者(useradd)的時候，這個目錄下的所有檔案會自動被複制到新新增的使用者的家目錄下。執行下面指令查看/etc/skel

ls -la /etc/skel/

ls所包含的命令：

• -a 列出隱藏檔

• -l 列表方式顯示檔案 輸出結果：

drwxr-xr-x  2 root root 4096 Aug 24 09:03 .
drwxr-xr-x 96 root root 4096 Jul 25 10:34 ..
-rw-r--r--  1 root root  220 Apr 18  2019 .bash_logout
-rw-r--r--  1 root root 3523 Jan 11  2021 .bashrc
-rw-r--r--  1 root root 1010 Aug 24 09:03 .profile

指定 skel

新增使用者時可以透過命令來改變預設的/etc/skel目錄作為使用者配置檔案的目錄：

sudo useradd -d /home/jasonchen -m -k /etc/my_skel jasonchen

變更預設 skel

不想在每次新建使用者時，都重新指定新的使用者配置檔案的目錄，可以通過修改/etc/default/useradd配置檔案並查詢SKEL變數的定義：

# Default values for useradd(8)
#
# The SHELL variable specifies the default login shell on your
# system.
# Similar to DHSELL in adduser. However, we use "sh" here because
# useradd is a low level utility and should be as general
# as possible
SHELL=/bin/bash
#
# The default group for users
# 100=users on Debian systems
# Same as USERS_GID in adduser
# This argument is used when the -n flag is specified.
# The default behavior (when -n and -g are not specified) is to create a
# primary user group with the same name as the user being added to the
# system.
# GROUP=100
#
# The default home directory. Same as DHOME for adduser
# HOME=/home
#
# The number of days after a password expires until the account
# is permanently disabled
# INACTIVE=-1
#
# The default expire date
# EXPIRE=
#
# The SKEL variable specifies the directory containing "skeletal" user
# files; in other words, files such as a sample .profile that will be
# copied to the new user's home directory when it is created.
SKEL=/etc/skel
#
# Defines whether the mail spool should be created while
# creating the account
# CREATE_MAIL_SPOOL=yes

如果此變數的定義已被註釋掉，可以取消註釋，然後修改其值：

SKEL=/etc/my_skel
