This TUI application includes 50+ questions meant to be solved using GNU sed. Some exercises will require you to combine sed with other standard commands such as tac, wc and tr.
Note
This application is intended to be run in a Linux-like environment. You might still be able to solve the exercises on other platforms, but I do not know if that'll work.
This app is available on PyPI as sedexercises. Example installation instructions are shown below, adjust them based on your preferences and OS.
# virtual environment
$ python3 -m venv textual_apps
$ cd textual_apps
$ source bin/activate
$ pip install sedexercises
# launch the app
$ sedexercisesTo run the app without having to enter the virtual environment again, add this alias to .bashrc (or equivalent):
# you'll have to change the path
alias sedexercises='/path/to/textual_apps/bin/sedexercises'As an alternative to manually managing such virtual environments, you can use https://github.com/pypa/pipx instead:
$ pipx install sedexercises
$ sedexercisesAs yet another alternative, you can install textual (see Textual documentation for more details), clone this repository and run the sed_exercises.py file.
Adjust the terminal dimensions for the widgets to appear properly, for example 84x25 (characters x lines). Here's a sample screenshot:
