On Linux, you can save a screenshot of your currently focused window every X interval.
These are some of my screenshots, previewed with
sxiv image viewer.
Why would you want to do so? So you have a high definition record of what you’re working on back then, so in the future you have a better contrast of how much you and your computing environment have changed over time.
For example, I can look back and pin point the exact day I switched to Vim from Typora as my main text editor. This puts things into perspective, the time certain things happened is no longer a vague memory that fades over time without recovery.
This can be achieved with 3 tools
- the bash script below
$ sudo apt-get install scrot
Save this bash script
#!/bin/bash #cd to script location cd "$(dirname "$0")" date_string=$(date --iso-8601=date) folderName=$date_string mkdir -p ~/Pictures/cron_scrot_snapshot/$folderName DISPLAY=:0 scrot -u ~/Pictures/cron_scrot_snapshot/$folderName/%Y-%m-%d_%H:%M:%S_scrot.png
This bash script creates a folder with the current date, in ISO8601 format (e.g. 2020-05-02) and saves the currently focused window into the date folder as a png file.
This is what the directory structure would look like.
Setting up a cronjob
You can set up a cronjob to run the script every X interval, for example every 5 minutes.
