Review

I always don’t kwnow enough about repo, so I read some articles about repo this week. These articles describe the repo Manifest format, usage of repo, repo && git , etc in detail. It helps me a lot. But I have not absorbed them yet, I need more time.

The links are as follows:

• Source Control Tools
• Source Control Workflow
• Repo Command Reference
• Repo Manifest Format
• Repo hooks
• How to separate topic branches

Tips

• Delete Files Using Extended Pattern Matching Operators.

  # enable extglob
  shopt -s extglob
  
  rm -v !("filename")
  rm -v !("filename1"|"filename2") 
  # such as,
  rm -i !(*.zip)
  rm -v !(*.zip|*.odt)
  
  # disable extglob
  shopt -u extglob

• Delete Files Using Linux find Command

  find /directory/ -type f -not -name 'PATTERN' -delete
  find /directory/ -type f -not -name 'PATTERN' -print0 | xargs -0 -I {} rm {}
  find /directory/ -type f -not -name 'PATTERN' -print0 | xargs -0 -I {} rm [options] {}
  # such as,
  find . -type f -not -name '*.gz'-delete
  find . -type f -not -name '*gz' -print0 | xargs -0  -I {} rm -v {}
  find . -type f -not \(-name '*gz' -or -name '*odt' -or -name '*.jpg' \) -delete
