Bash Online Test

You ran a script that wrongly put its output image files in the 'work' directory inside the current directory.

Create a bash script that removes all the files in the 'work' directory that start with either 'out_0' or 'out_1' and end with '.png'.

For example, if the 'work' directory contains the following files: 

After running your script, both out.png and out_0.pdf should exist in the 'work' directory but out_0a.png and out_1.png should no longer exist.

See the example case for more details.

The weather.sh utility in the current working directory provides weather forecasts in your area.

When called, it outputs a 4-day forecast in the format "day: weather" separated by line breaks.

Write a bash script that outputs the number of days with a "Thunderstorm" forecast (case-sensitive).

See the example case for more details.

Select the statements about the output of the following script that are correct.

#!/bin/bash

value=$1

if [ "$value" -eq 100 ]; then
    echo "value is eq 100"
elif [ "$value" -gt 100 ]; then
    echo "value is gt 100"
else
    case "$value" in
    [1-3]*) echo "value is between 1 and 39 (inclusive)" ;;
    [4-5]*) echo "value is between 40 and 59 (inclusive)" ;;
    9[1-8]) echo "value is between 91 and 98 (inclusive)" ;;
    99) echo "value is $value" ;;
    *) echo "value is unknown" ;;
    esac
fi

The PATH variable is set in /etc/environment: 

PATH="/usr/local/sbin:/usr/local/bin:/usr/games:/usr/local/games"

And updated in .bash_profile:

export PATH=/usr/temp:$PATH:/usr/local/apps

Select the statements are correct.
