Spec for a tool I want written but am too lazy to make happen: journal - an append-only personal log.

Timestamps all input and appends it to a log file. Inputs can be either arguments to the command, or read from stdin if piped to.

Log file should be parseable with grep and other coreutils, but an indexed option might be useful for time range queries.

You want something like https://jrnl.sh

I’ve used this for a few years now and it’s pretty solid.

To write:

    systemd-cat -t mylogs <<< "Message"

To read:

    journalctl -t mylogs --since yesterday

Systemd logs get rotated. :)

Systemd logs get huge in practice. Binary format, also.

Still, nice hack value.
