Problem solving

1. Try in docs.csc.fi in the right section in the hierarchy
2. Try in the FAQ
3. Try the search if docs or in google for it
4. Send an email to servicedesk@csc.fi containing:
   • A descripte title
   • What you wanted to achieve, and which on which computer
   • Which commands you had given
   • What error messages resulted
   • More tips to help us quickly solve your issue)

Docs challenge: What is the name of the command that copies the file to Allas and makes it available directly from the internet?

Learning a new method or application

• If it comes with tutorials, do at least one
  • This will likely be the fastest way forward
• Check if there’s a page for it in docs.csc.fi/apps/
  • If there is, use the batch script example from there
• First try a small / quick job and when you’re sure it works, scale up

Document your discoveries

• When you’ve successfully solved an issue, make it easy to rediscover it
• Set up a file in your $HOME and add your commands there with keywords for yourself
  • e.g. it’s quick to copy/paste your command from the screen to the end of the file

cat >> $HOME/vault
<copy/paste>
Ctlr-C

• and grep‘ing it later is quick
• Store scripts in $HOME/bin and take backups

Keep notes

Save useful commands and short scripts to a file for later reference, and push your notes to GitHub every now and then. Bash history keeps all the commands that you typed, but it also keeps the ones that did not work…
