Useful cluster commands

[emolinab]

The idea of this discussion is to collect helpful cluster commands. Here are a few I used/learned during our landuse folder space "crisis" :

1. Delete a folder: rm -rf <FOLDER>
2. Copy one file to another folder: cp file.txt <NEW FOLDER>
3. Copy one folder to another: cp -R <FOLDER> <NEW FOLDER>
4. Move one file to another folder: mv file.txt <NEW FOLDER>
5. Move one folder to another folder: mv <FOLDER> <NEW FOLDER>
   6) Space available and used in a folder: mmlsquota -j <FOLDER> --block-size T projects
   7) Space occupied in a directory by file and subfolder: du -h
6. Space occupied per folder and sorted in the current directory: du -h -d 1 | sort -rh (add >> du.txt to save results in a .txt file)

1. Start an interactive shell session on a compute node: srun --qos=priority --pty bash
2. Show running processes of a user: ps -fu <username>
3. Search all files recursively from the current working directory for a string: rg <search string>, use -Tjson to exclude json files
4. Search all pik-piam repos for a string: reposearch <search string>, use -Tjson to exclude json files
