Lab 4 Browsing the Filesystem

Sequence 1: Directory and File Organization

1. Log in as user student with the password student.

2. [student@stationX ~]$ pwd
/home/student

3. ls
    ls -a
    ls -al
-a option includes files whose names begin with a period and used for storing configuration information
The fifth column of ls -l's output displays the file's size.

4. [student@stationX ~]$ touch {report,graph}_{jan,feb,mar}

5. [student@stationX ~]$ ls

6. Make directory
[student@stationX ~]$ mkdir Projects
[student@stationX ~]$ mkdir Projects/graphs
[student@stationX ~]$ cd Projects
[student@stationX Projects]$ mkdir reports
[student@stationX Projects]$ cd reports
[student@stationX reports]$ mkdir ../Backups

[student@stationX reports]$ cd
[student@stationX ~]$ ls -l
[student@stationX ~]$ ls Projects

7. Move files
[student@stationX ~]$ mv graph_jan Projects/graphs
[student@stationX ~]$ mv graph_feb graph_mar Projects/graphs
[student@stationX ~]$ ls -l Projects/graphs/

8. Move the files in one command:
[student@stationX ~]$ mv report_jan report_feb Projects/reports
[student@stationX ~]$ ls -l Projects/reports

9. Remove the remaining report file:
[student@stationX ~]$ rm report_mar
[student@stationX ~]$ ls

10. Copy one using an absolute pathname and the other using a relative pathname:
[student@stationX ~]$ cd Projects/Backups
[student@stationX Backups]$ pwd

[student@stationX Backups]$ cp ../reports/report_jan .
[student@stationX Backups]$ cp /home/student/Projects/graphs/graph_jan .
[student@stationX Backups]$ ls -l
