Exercise bash
Hi, I started to take a look at the bash of linux and do some exercises like this ....
1) Extract (and print on standard output) from the file / etc / passwd login-name and home file (first and sixth fields) as follows:
- only login-names that have the home in '/ home /'
- alphabetical order
Example:
Alice / Home / Alice
bob / home / bob
Paul / home / Paul
I don't quite understand which commands I should use, could someone help me?
