Just annotations of little "how to's", so I know I can find how to do something I've already done when I need to do it again, in case I don't remember anymore, which is not unlikely. Hopefully they can be useful to others, but I can't guarantee that it will work, or that it won't even make things worse.

Simple idea for a debug verbosity tool on bash scripts

I used to just have lots of "echos" around my scripts printing where it is on a loop or whatever, so I have a better idea of whats happening, often somewhat more clear than with "bash -x", even though that also may help, of course. But the odds are that I'd at some point just leave such debug echos there while the script runs on a daily basis on the background, just helping .xsession-errors to become enormous, for no good reason, since it's working and I'm not reading it. And then it can take some time to go and comment all the needless echos and printfs, paying attention if they're really just debug messages.

A simple alternative is to have either a function or perhaps an auxiliary script at $PATH that would echo what's put in front of it "debug=1" or something. Maybe it can even be somewhat tweaked to have degrees of verbosity.

Code:
#!/bin/bash

dbgecho() {
(( debug > 0 )) && echo $@
}

debug=1

dbgecho "whatever man, debugmsg"
dbgecho -e "debug\ndebug\ndebug"

debug=0

dbgecho "nah"
