LINUX ASSIGNMENT

[] - indicates a placeholder for a command that needs to be executed either directly

or using command substitution.

Write a bash function called mystats(), which reports the following:

Print the following text or results of commands to standard output.

(HINT: Use command substitution when output for a command is on the same line

as other text.)

"[username], welcome to mystats for [your host name here]"

"Current date/time is [current date/time]"

"================================================"

"Uptime report"

[show system up time using the command uptime]

"================================================"

"Your currently running processes"

[show the running processes for the username]

"================================================"

"Disk Usage Report"

[show a human readable disk usage report using the command df -h]

"================================================"

"Have a great day!"

"================================================"

Tips:

Test the function by placing it in your .bashrc or .bash_profile.

Blackboard submission information:

After testing, create a directory called stats.

Create a file called mystats.sh which contains your function.

Create a tarball of the stats directory and upload to Blackboard

Example output when I run the function at the command line:

$ mystats
