About the test

The Bash online test assesses knowledge of programming Bash scripts for a Linux environment. This test contains a series of live coding tasks that are executed on the Ubuntu server.

The assessment includes work-sample tasks such as:

  • Searching for files and their content.
  • Working with Unix pipelines for interprocess communication.
  • Using environmental variables to affect the behavior of running processes.

A good Bash developer or Linux administrator needs a solid understanding of the Bash scripting language as well as knowledge of Bash language constructs and commonly available utilities in Linux systems.

Sample public questions

Unix Pipelines

The 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.

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: 

The 'work' directory contains png and pdf 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.

Decorative quote

Simple, straight-forward technical testing

TestDome is simple, provides a reasonable (though not extensive) battery of tests to choose from, and doesn't take the candidate an inordinate amount of time. It also simulates working pressure with the time limits.
