for everything else that doesn't fit? Something a beginner would understand, but is a helpful shortcut or common task. I'm thinking of:

• using cd -
• for file in *.fq; do echo $file; mv $file ${file/.fq}.fastq; done
• tee #24
• reading lines from a file with while read line

discuss!

There's a pretty popular repository with just that--tips and tricks: https://github.com/jlevy/the-art-of-command-line/blob/master/README.md#everyday-use

Maybe we could pick out the more useful and beginner friendly ones for this section.

Thanks for the tip! Maybe we can link to this somewhere in the lesson...
