Hi,
I was looking for a way to timestamp output from a serial port when I
stumbled onto a tool that I'd never heard of. The ts command, which is
part of moreutils, will place a timestamp in front of each line of
output from stdout.
This:
echo -e "foo\nbar\nbaz" | ts '[%Y-%m-%d %H:%M:%S]'
yields something like this:
[2021-07-27 13:37:36] foo
[2021-07-27 13:37:36] bar
[2021-07-27 13:37:36] baz
Combined with picocom and tee, my logging command looks like this:
picocom -b 9600 /dev/ttyUSB0 | ts '[%Y-%m-%d %H:%M:%S]' | tee
"example_$(date +"%Y%m%d%H%M%S").log"
moreutils contains about a dozen other commands which might come in
handy at some point.
