Does your 1:, 2:, 3: are actually inside the content of the file?
If no, you may try the following:
$1 is your text file name.
If no, you may try the following:
#!/bin/bash
while read LINE
do
if [ $LINE = "EOF" ]; then
break
fi
useradd $LINE
done < $1
$1 is your text file name.
try this
awk -F":" filename '{ print $2 } | while read username
do
if $username == 'EOF'
then
exit
fi
useradd $username
done
awk -F":" filename '{ print $2 } | while read username
do
if $username == 'EOF'
then
exit
fi
useradd $username
done
for i in `cat text | awk -F: '{print $2}'`; do
echo $i
if [ "$i" = "EOF" ]; then
exit
fi
useradd $i
done
echo $i
if [ "$i" = "EOF" ]; then
exit
fi
useradd $i
done
Sorry, try this:
awk -F":" '{ print $2 }' textfile.txt | while read username
do
if [ "$username" = "EOF" ]; then
exit
fi
useradd $username
done
awk -F":" '{ print $2 }' textfile.txt | while read username
do
if [ "$username" = "EOF" ]; then
exit
fi
useradd $username
done
Sorry friends
I am new in Linux scripting
I have problem with reading files and receive that error
awk: cmd. line:1: fatal: cannot open file `userfiles.txt' for reading (No such file or directory)

That means it can not find your file. Did you create a file called userfiles.txt? If so where is it? Try using the full path in the script like this:
awk -F":" '{ print $2 }' /path/to/userfiles.txt | while read username
do
if [ "$username" = "EOF" ]; then
exit
fi
useradd $username
done
awk -F":" '{ print $2 }' /path/to/userfiles.txt | while read username
do
if [ "$username" = "EOF" ]; then
exit
fi
useradd $username
done
This is my code
awk -F":" '{ print $2 }' /Desktop/Assignment/userfi
do
if [ "$username" = "EOF" ]; then
exit
fi
useradd $username
passwd $username
done
awk: cmd. line:1: fatal: cannot open file `/Desktop/Assignment/userf
awk -F":" '{ print $2 }' /Desktop/Assignment/userfi
do
if [ "$username" = "EOF" ]; then
exit
fi
useradd $username
passwd $username
done
awk: cmd. line:1: fatal: cannot open file `/Desktop/Assignment/userf
ok, try this path:
/root/Desktop/Assignment/u
Also, try this command and post the output:
cat /root/Desktop/Assignment/u
If it does not print out the file then that means the file is not there.
/root/Desktop/Assignment/u
Also, try this command and post the output:
cat /root/Desktop/Assignment/u
If it does not print out the file then that means the file is not there.
and If user already exist then it should not add the user
Need script for this
Sorry to disturb you again and again savone

useradd will not add a user if it already exists, it will just error out.
Use this code to add the password. Although this is frowned upon (using the same password as username) and some systems might reject the password telling you it is using the username.
