Instructions
Create a file easy-perm.sh, which will change the default permissions for the example.txt and example2.txt files inside the folder easy-perms, to the ones below:
Expected Output:
$ ls -l easy-perm
total 8
-rwxr--rw- 1 user user 689 dez 13 16:14 example2.txt
-rw-r--r-- 1 user user 348 dez 13 16:14 example.txt
$
Hints
-chmod The chmod, or change mode, command allows an administrator to set or modify a file’s permissions. Every UNIX/Linux file has an owner user and an owner group attached to it, and every file has permissions associated with it. The permissions are as follows: read, write, or execute.
This is what the default permissions looks like when you create a file.
$ touch example.txt
$ ls -l example.txt
-rw-rw-r-- 1 user user 348 dez 13 15:31 example.txt
$
This is what it looks like if you want to give permissions to read, write and execute to every group.
$ chmod 777 example.txt
$ ls -l example.txt
-rwxrwxrwx 1 user user 348 dez 13 15:31 example.txt
$
