I had a need to add about 70 users at once into the smbpasswd file for our new file server here at work, so i made this script :-)
Just thought i would share it with everybody, since i couldn't find anything like it on the net, maybe somebody else has a need for a script like this.
The actual script:
#!/bin/bash
##########################################################
## This script is here to make adding/subtracting users ##
## to the smbpasswd file easyer etc. ##
##########################################################
NO_ARGS=2
E_OPTERROR=65
operation=0 # 1 = add
# 2 = del
# 0 = error.
fillel=0 # 1 = good file and file location.
# 0 = error
#########################################################
## Parameters: ##
## -o [options] = The operation to preform. Options are##
## as follows: ##
## add = add users to the system ##
## del = delete users from the system.##
## -f [file_location] = The file that the user names ##
## are stored in. must provide ##
## the compleate location of the ##
## file. ##
#########################################################
#protect outselfs from passing nothing to the script.
if [ "$#" -eq "$NO_ARGS" ]
then #script needs at least 3 options passed to it, otherwise error out and do nothing.
echo "Usage: $0 -[switch] [option/file_location]"
exit $E_OPTERROR
fi
while getopts o:f: Option
do
case "$Option" in
o)
#check the option and fill the operation var.
if [ "$OPTARG" == "add" ]
then
#we are going to add the users.
operation=1
elif [ "$OPTARG" == "del" ]
then
#we are deleting the users.
operation=2
else
#error out, cause they didn't pass the right option.
operation=0
echo "Invaild operation option!"
exit $E_OPTERROR
fi
;;
f)
#check the option to see if the file exsists and that it is none zero.
if [ -f "$OPTARG" ]
then
if [ -s "$OPTARG" ]
then
filel=1
filelocation="$OPTARG"
else
filel=0
echo "File is of zero length! You need to have a list of users in the file!"
exit $E_OPTERROR
fi
else
filel=0
echo "File isn't there! You must provide a vlid file location!"
exit $E_OPTERROR
fi
;;
*)
break
;;
esac
done
shift $(($OPTIND - 1))
if [ $operation == 1 ]
then
#we are adding the users.
for i in $(cat "$filelocation")
do
username=$(echo "$i" | cut -d':' -f1)
password=$(echo "$i" | cut -d':' -f2)
smb-passwd-add $username $password
done
elif [ $operation == 2 ]
then
#we are deleting the users out of the system.
for i in $(cat "$filelocation")
do
username=$(echo "$i" | cut -d':' -f1)
smbpasswd -x $username
done
fi
exit 0
i also had to make a script to make smbpasswd a non interactive script. It uses expect to do so :-)
smb-passwd-add:
#!/usr//bin/expect --
# wrapper to make passwd(1) be non-interactive
# username is passed as 1st arg, passwd as 2nd
# Executable only by root
set password [lindex $argv 1]
spawn /usr/bin/smbpasswd -a [lindex $argv 0]
expect "password:"
send "$password\r"
expect "password:"
send "$password\r"
expect eof
the input file needs to be formatted like this:
username:password
username:password
anyways, just thought that i would share :-)
