+description: "A small logging library for bash. Supports `cli`, `json`, `logfmt`, and custom formats. Integrates with journald and Github actions."
+category: bash
+tags: [library, logging]
+---
+
+See https://github.com/orbit-online/records.sh for the full README and more
+advanced use-cases.
+
+## Usage
+
+Source the script with `source "records.sh"` and log messages with the
+lowercased loglevel as the function name:
+
+```
+debug 'Starting up.'
+verbose 'Startup completed'
+info 'Hello world!'
+warning 'Careful!'
+error 'Oh no!'
+```
+
+The method signature of the logging functions mimic that of `printf`:
+`info FORMAT [ARGS...]`. Which means you can format variables.
+
+```
+$ var=0x1f
+$ info "The decimal version of %s is %d" "$var" "$var"
+example.sh: The decimal version of 0x1f is 31
+```
+
+All log messages are output to stderr. If you want to log something to stdout
+simply run e.g. `info 'message' 2>&1`.
