In this section, we are going to learn how to create users and groups through a shell script.
Now, we will create a script to add a user. The useradd
command is used to create a user. We are going to use the while
loop, which will read our .csv
file, and we will use the for
loop to add each user that's present in that .csv
file.
Create a script using add_user.sh
:
#!/bin/bash #set -x MY_INPUT='/home/mansijoshi/Desktop' declare -a SURNAME declare -a NAME declare -a USERNAME declare -a DEPARTMENT declare -a PASSWORD while IFS=, read -r COL1 COL2 COL3 COL4 COL5 TRASH; do SURNAME+=("$COL1") NAME+=("$COL2") USERNAME+=("$COL3") DEPARTMENT+=("$COL4") PASSWORD+=("$COL5") done <"$MY_INPUT" for index in "${!USERNAME[@]}"; do useradd -g "${DEPARTMENT[$index]}" -d "/home/${USERNAME[$index]}" -s /bin/bash -p "$(echo "${PASSWORD[$index]}" | openssl passwd -1 -stdin)" "${USERNAME[$index]}" done
