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.

[bash] "keep trying" command, even if exits with error, for at least 10 times

A script that tries to run a given arbitrary command N times, or until it exits with success. The commented parts are aborted attempts to make it figure whether the first parameter is a number instead of a command, and that would be used as the maximum number of attempts. Something went wrong, sometime I'll try to figure it out.

#echo $input | grep "^[[:digit:]]" && ( echo "then" ; command="$(echo $input | sed 's|^[[:digit:]]\ ||')" ; max=$(echo $@ | sed 's|\ .*||') ) || echo "else" ; export command="$input" ; max=10
#echo $command
max=10
#echo $max
attempts=0
false ; until [[ $? -eq 0 ]] || ((attempts>(max-1))) ; do attempts=$((attempts+1)) ; echo $attempts ; $@ ; done

    Hey I had to give this one a shot on trying to get it to work for n tries, came up with a promising result, if interested.

    Heck, I posted it, if you'd like:
