On-Prem: Useful commands for Administration


Backend Log - Show last 15 entries and track and real time:

cat <COYO_DATA_STORAGE>/backend/logs/coyo-backend.log -f tail -15


Directory size - Show folder sizes in the current directory and sort in descending order:

Aliases – Aliases are abbreviations for longer commands that you can create yourself. These are configured in the file .bashrc in the respective user directory. 
A Bash alias has the following structure:

alias [alias_name]=\"[command_to_alias]\"

Here are a few aliases from us, simply copy these into the file:

db-connect - a direct connection from the Docker host to the PostgreSQL database:

alias db-connect='docker exec -it $(docker ps | grep db_1 | cut -d\" \" -f1) psql --username=<COYO_DB_USER> <COYO_DB_NAME>'

backend-log - Shows and tracks the last 15 entries from the backend log:

alias backend-log='docker logs -f $(docker ps | grep backend_1 | cut -d\" \" -f1) --tail 15'

dirsize - Lists all folders and their size in the current directory and sorts them in descending order:

alias dirsize='ls | xargs -I {} du -shx {} | sort -rh'

After saving and closing the file, you only need to execute the following commands for your aliases to be executed:

source .bashrc

<>PostgreSQL Database
