Converting a scanned document to a pdf document ---------- Last year I did some consulting for a law firm that required me to submit time sheets with my invoices. In any given invoice period I would undertake work involving multiple clients. Work undertaken for each client was broken down into standard categories, telephone call, email, meeting, etc. text/html 2017-10-12T10:58:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.mlug-au.org/doku.php?id=tutorials:bash_scripting:part2&rev=1507805892&do=diff 3. Adding a GUI interface to a bash script ---------- GUI interfaces can be used with bash scripts. The script below uses Zenity to provide a GUI dialog for selecting an image to convert to .pdf, a second GUI dialog for naming and saving the newly created .pdf file and a third offering the option to delete the image file used to create the .pdf file. text/html 2017-10-12T10:58:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.mlug-au.org/doku.php?id=tutorials:bash_scripting:part3&rev=1507805892&do=diff 3. Creating a configuration file on the fly and stream editing ---------- Someone on the list asked If I'd do something with stream editors. In this tutorial I'll use pipes, grep, sed and awk to help set a variable in a configuration file when I log into a session. Grep in this case will be used to print lines matching a given pattern to stdout. Sed will be used to print only one line piped from grep to stdout. Awk will be used to print just one field from the line piped in from sed. text/html 2017-10-12T10:58:12+00:00 Anonymous (anonymous@undisclosed.example.com) https://www.mlug-au.org/doku.php?id=tutorials:bash_scripting:part4&rev=1507805892&do=diff Building a script with functions that encodes and shrinks videos ---------- The previous tutorials were on the short side. Heres one to make up for my brevity :^) If something is unclear check those other tutorials to see if it is explained there.

No matter how many times I read bash scripting manuals and tutorials it was all just a bunch of hello worlds and loops that count to ten. Nothing much stuck until I had something that I wanted to do.
