Code:
#!/bin/bash  while read LINE do   
echo useradd "$LINE" -d /home/$LINE
useradd "$LINE" -d /home/$LINE
 done < $1

Will work properly. Thanks, but what when i want to put "load" data from data.txt instad of keyword like LIKE???? I mean for example for $i in "here i will put name of the file etc" is that possible? or similar way like i did it within first post?

When it comes to Corona's version

Code:
while read LINE do         
echo useradd "$LINE" -d /home/$LINE
useradd "$LINE" -d /home/$LINE
 done < data.txt

Also works properly. Thank both of You!
