comment
is a simple tool to add comments to process invocations.
For example you can run the following command in one shell:
comment this is a sleep command -- sleep 10
and then if -- within 10 seconds -- you run this command in another shell:
ps aux | grep sleep
the output of that will include something like:
shahn 1003826 0.0 0.0 3072 1920 pts/12 S+ 15:12 0:00 comment this is a sleep command -- sleep 10
