我需要能够在我的Linux (Fedora 10)上创建用户帐户,并通过bash脚本自动分配密码(如果需要,也可以采用其他方式)。
通过Bash创建用户很容易,例如:
[whoever@server ]# /usr/sbin/useradd newuser
是否可以在Bash中分配密码,功能类似于此,但自动:
[whoever@server ]# passwd newuser
Changing password for user testpass.
New UNIX password:
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[whoever@server ]#
这里有一个脚本,将为您.....
如果你愿意,你可以添加一个用户列表(或者只是一个用户),一次完成,每个用户都有不同的密码。作为奖励,脚本的末尾会显示每个用户的密码. ....如果您愿意,您可以添加一些用户维护选项
如:
chage -m 18 $user
chage -M 28 $user
到将设置密码年龄等的脚本。
= = = = = = =
#!/bin/bash
# Checks if you have the right privileges
if [ "$USER" = "root" ]
then
# CHANGE THIS PARAMETERS FOR A PARTICULAR USE
PERS_HOME="/home/"
PERS_SH="/bin/bash"
# Checks if there is an argument
[ $# -eq 0 ] && { echo >&2 ERROR: You may enter as an argument a text file containing users, one per line. ; exit 1; }
# checks if there a regular file
[ -f "$1" ] || { echo >&2 ERROR: The input file does not exists. ; exit 1; }
TMPIN=$(mktemp)
# Remove blank lines and delete duplicates
sed '/^$/d' "$1"| sort -g | uniq > "$TMPIN"
NOW=$(date +"%Y-%m-%d-%X")
LOGFILE="AMU-log-$NOW.log"
for user in $(more "$TMPIN"); do
# Checks if the user already exists.
cut -d: -f1 /etc/passwd | grep "$user" > /dev/null
OUT=$?
if [ $OUT -eq 0 ];then
echo >&2 "ERROR: User account: \"$user\" already exists."
echo >&2 "ERROR: User account: \"$user\" already exists." >> "$LOGFILE"
else
# Create a new user
/usr/sbin/useradd -d "$PERS_HOME""$user" -s "$PERS_SH" -m "$user"
# passwdgen must be installed
pass=$(passwdgen -paq --length 8)
echo $pass | passwd --stdin $user
# save user and password in a file
echo -e $user"\t"$pass >> "$LOGFILE"
echo "The user \"$user\" has been created and has the password: $pass"
fi
done
rm -f "$TMPIN"
exit 0
else
echo >&2 "ERROR: You must be a root user to execute this script."
exit 1
fi

希望这能有所帮助。

我知道我要过几年才会有这个想法,但我不敢相信居然没有人建议用户mod。
usermod --password `perl -e "print crypt('password','sa');"` root
如果有人想在旧的HPUX上执行此操作,您可以使用usermod.sam。
/usr/sam/lbin/usermod.sam -F -p `perl -e "print crypt('password','sa');"` username
只有当执行脚本的人是当前用户时才需要使用-F。当然,您不需要使用Perl来创建散列。您可以使用openssl或许多其他命令来代替它。
