The other C-program I have today is a coreutils viewer, appearing as cv on Github. No, just for the record, I don’t dredge Github looking for new material. As it would happen, most titles these days are submitted from readers, and thrown into the hat.
This one was relayed to me by e-mail, and I realized later that I actually had it on my list as coreutils-viewer, so it’s possible I copied that name from elsewhere on the Internet. Regardless. …
Some other tools to amplify the output of core utilities — like pv or Advanced Copy — attempt to integrate themselves into the command, or pipe through it. cv, as you can see above, takes the sidelong approach by checking for running instances of
grep and a bunch of others, and showing their progress as a summary.
It’s an interesting solution to the long-standing issue of less-than-communicative programs, like
cp. And goodness knows those have bothered me for quite some time.
cv has a few options to keep you busy; it has a monitor mode with
-m, that will loop until processes finish, and another monitor mode with
-M which will loop indefinitely, allowing you to keep it on screen as a kind of coreutils process monitor. I like that.
And there is a filter option with
-c that lets you trim the display to only one particular process. Not much more than that, but simple is best.😉
I think I shall keep cv on board for a little while longer. I like the idea of having a continuous monitor of coreutils processes, even if I am quickly approaching a system made up completely of monitors, and nothing actually doing any work.🙄
