Objective:
Practice common UNIX commands.
Procedure:
- The following list of Unix commands are given for self-learning. Use 'whatis' or 'man' command to find out about each command. Your document should include the description or screen shots of the output from each of the command.
Commands:
- df
- du
- gzip
- file
- history
- wget
- Changing access rights:
chmod u+x Dir1.0 adds execute permission for the owner
chmod go-w file1 removes write permission for the group and others
chmod ugo=rw testfile sets the permissions for everyone to read and write, but not execute
chmod u=rwx newDir sets the permissions for the owner to read, write, and execute
- How to check access rights for files or directories?
-
- Use the command in (a) to find out the access rights for the file named /etc/passwd.
- Who is the owner of this file?
- What is the permission for the group on this file?

Consider the list of animals and their attributes given below
cell (CELL_Q3_INPUT). The objective is to obtain the print outs in
the subsequent cell (CELL_Q3_OUTPUT). Note that the attributes of
each animal are 'name', 'species', 'color', and 'age'. You
must use collections.namedtuple to add readable
attribute references, which then will be used to generate the
desired output in CELL_Q3_OUTPUT.
# CELL_Q3_INPUT
