Please Help On Simple Shell Script
This is an assignment I have to do everyone but I was viewing the threads and I assumed that I could write this assignment simpler than what My instructor is directing..
Here is the Assignment
This shell script has the following specifications:
- It must be named: "printpasswd."
- It must take one argument from the command line. The argument will point to a file that follows the /etc/passwd format.
- It will parse the file and output each user's information in the following format: user-name, uid, gid, home, shell and notes.
For example, if the file contains the following information, root:FP3mDXRh.KTMQ:0:0:root:/root:/bin/sh, then the output should be
"user-name uid gid home shell notes root 0 0 /root /bin/sh root
Now I was wondering...Can the Script be simply written as Follows?:
#!/bin/bash
# This is the script for parsing the "printpasswd info"
$ chmod +x printpasswd
echo Username
echo User ID
echo Password
echo Group ID
echo Home
echo Notes
and Please don't laught because I'm novice at scripting and it seems as if 85% of the class has experience....so I'm in the dark on this could someone help me please..and thank You
