Question

Unix/Linux

The purpose of this lab is to practice the commands to manage and organize files and directories:

How would one go about this? Thanks.

Task 1: Preliminaries:
1) If you have not already done so, create a directory called bin under your HOME directory.
2) If you have not already made a copy (using ftp) of the file called famous.dat from the Assignment#1, do that now.
3) Make bin the active/working directory.

Task 2: Perform all of the following steps from the bin directory:
1) Copy the famous.dat file (from assignment 1) from your home directory into the this (bin) directory and call itfamous.data. (Hint: use ../ )
2) Create a directory called datafiles under this (bin) directory.
3) Make a copy of famous.data into the datafiles directory but use the name famous.backup
4) Make a hard link file called famous.hard into the datafiles directory, that links to famous.data
5) Make a symbolic/soft link file called famous.soft into the datafiles directory, that links to famous.data.Note: the soft link source needs to be an absolute path, as does the destination, since the destination is in a different directory.

Task 3: Submit Assignment 2 by turning in only the output and the commands below.

All commands must be entered from your bin directory.

a) Run the command to print your current working directory so I see the complete path of just that...the directory youare working from.

b) Use the following command to display both the current directory and the datafiles directory and inode values using the options for long (letter l) and inode (letter i):
ls -li . datafiles
(This shows an equal inode value for the hard link as well as the soft link reference: ->)

c) Use the following command to display the datafiles directory using the options lower and capital letter L:
ls -lL datafiles
(This will show the soft link de-referenced)

d) Use metacharacters and the ls -lL command (with lower and upper case L) to list all filenames under thedatafiles directory that contain a dot '.' with the letter 'f' or 'u' anywhere after the dot.

e) Use metacharacters and a single ls -lL command (with lower and upper case L) to list all file names that contain a dot '.' followed by a lower case letter, then end with the letter 't' or 'r' as the second from last character. And these files should be from your current directory as well as any directory under the current directory that contains the letters "data".
For example: data1/a.pqrs would be a match, but dabta.Dtu and datafiles/.soft do not match.
Hint: use two command arguments, one for the current directory, and one for directories the contain 'data'.

Sample Output (NOTE: details such as owner/inode/date will be different)

a) Here is sample output running commands on hills (your output will show your hills user ID):
/students/rpa/bin

b)
[rpa@hills bin]$ ls -li . datafiles
.:

12198384 lrwxrwxrwx 1 rpa b20003   33 Sep 5 15:01 famous.soft -> /students/rpa/bin/famous.data

c)

-rwx------ 2 rpa b20003 2401 Sep 5 14:25 famous.hard
-rwx------ 2 rpa b20003 2401 Sep 5 14:25 famous.soft

d)

-rwx------ 2 rpa b20003 2401 Sep 5 14:25 datafiles/famous.soft

e)

-rwx------ 2 rpa b20003 2401 Sep 5 14:25 datafiles/famous.hard
-rwx------ 2 rpal b20003 2401 Sep 5 14:25 famous.data
