     • 2. go to the directory exercise-inspecting-and-moving
     • 3. find out in which subfolder are example output files with the ending .output
     • 4. find out which of the output files contains the text "failed"
     • 5. copy the directory containing output files to the backup folder
     • 6. rename the output files to now have the ending .out
     • 7. there is a folder which is in the wrong place (this needs more details), can you move it to the right place?

   • exercise (15 min):
     • redirect script output to a file, but for this we would need to move this behind scripts. or move redirects to scripts
     • composing commands:
       • ls | grep
       • grep | sort | uniq > output
       • find something | xargs
7. Scripts (Jørn & Sabry)
   • permission and executable
