This is the code I have to create user accounts from a text file. The usernames are being from the text file, and i want to set the password to unix lab. This script does not however seem to work.
#!/bin/sh
for i in `cat unix_tuesday.txt`
password = "unixlab"
do
echo "adduser $i"
adduser $i
echo -e "$password" | passwd $password
done
There are a couple of issues :
do is wrongly placed)This should do what you requested :
#!/usr/bin/env bash
for i in $(cat unix_tuesday.txt); do
password=unixlab
adduser $i
echo $password | passwd $i --stdin
done
Also take into account that there is a difference between adduser and useradd.
Running this through ShellCheck reports:
Line 2:
for i in `cat unix_tuesday.txt`
^-- SC1073: Couldn't parse this for loop. Fix to allow more checks.
Line 3:
password = "unixlab"
^-- SC1058: Expected 'do'.
^-- SC1072: Expected 'do'. Fix any mentioned problems and try again.
The password assignment is in between the for and the do. Moving it to the beginning yields a new set of errors:
Line 2:
password = "unixlab"
^-- SC1068: Don't put spaces around the = in assignments.
Line 3:
for i in `cat unix_tuesday.txt`
^-- SC2013: To read lines rather than words, pipe/redirect to a 'while read' loop.
^-- SC2006: Use $(..) instead of legacy `..`.
Line 6:
adduser $i
^-- SC2086: Double quote to prevent globbing and word splitting.
Line 7:
echo -e "$password" | passwd $password
^-- SC2039: In POSIX sh, echo flags are undefined.
man adduser
-p, --password PASSWORD The encrypted password, as returned by crypt(3). The default is to disable the password.
Note: This option is not recommended because the password (or encrypted password) will be visible by users listing the processes.
