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.

N00b method to toggle some verbosity on command for bash scripts

Just something I came up with that is probably not how actual programmers/scripters(?) would advise, specially the parameter/flag thing which is beside the point here.

Code:
if [[ $1 == "v" ]] ; then

ver(){
echo $@
}

else

ver(){
:    # ":" is a "do nothing" command
}

fi

a=10

echo normal output

ver verbose output $a

echo whatever man

exit 0
Don't try replacing ":" with "true". Somehow that spawns an infinite number of the same scripts.
