Changing File Permissions

Once logged in we'll create a file and set permissions on it in various ways.

$ echo test file > working.txt

$ ls l working.txt

Write permissions of woking.txt file ????????(need answer)(show input and output)

$ chmod 444 working.txt

Check permissions using list (ls l) command and Write the new permissions of woking.txt file. (SHOW ANSWER, INPUT AND OUTPUT)

In spite of the fact that the file does not have write permission for the owner, the owner can still change the file's permissions so that they can make it possible to write to it.

$ chmod 744 working.txt

Or, you can do this by using this form of chmod:

$ chmod o+w working.txt

What happens? Define the output? (Use ls l) commands to check the permissions) __________________________________________________________ ?????

$ chmod u-r working.txt

What happens? __________________________________________________________

$ chmod 777 working.txt

What happens? __________________________________________________________
