Question

1. Write 4 simple shell scripts. Each question will ask you to write one or more command lines to solve a problem. Put the command(s) from each problem into a file named problem1.sh, problem2.sh
Note that if you want your script to be interpreted by bash, each file should start with the line: #!/bin/bash and will have one (or more, as needed) commands following it.
To execute each script in bash, so you can determine if it is working or not, you can use command chmod to make it executable first. For example, for problem1.sh, you can do the following:
                -bash-4.1$ chmod +x problem1.sh
-bash-4.1$ ./problem1.sh
which will execute the command(s) in the script.

2. Write a script that will use commands echo, date, cal to print the account name of the person executing the script, the date when the script is being tested, and the month.
The following lists the result when I test my script.
-bash-4.1$ ./problem1.sh
asmith is testing this script on Tue Apr 12 23:08:10 MST 2016 in April 2016

Answer 1

#!/bin/bash
USER=$(whoami)
echo $USER " is testing this script on" `date`
cal -h

Explanation

1st line tell shell to execute this code as bash program

2nd line gets name of userexecuting this script in variable USER using command 'whoami'

$ is used to assign value of whoamito variable USER

echo outputs the concent on shell so $USER prints value of variable USER and the content in ""

date prints todays date and time. It is placed in `` quotes to interpret it as command

cal -h prints calendar of ongoing month and -h turns off highlightof todays date.
