Achieve fcrackzip parallel cracking by using xargs

start-fcrackzip.sh

logfile=$(date +%Y%m%d%H%M).log
targetfile=test.zip

# Start 1 processes for cracking mixalpha-numeric maximum 5 digits
fcrackzip -c Aa1 -b -l 1-5 --verbose -u $targetfile & >> $logfile &

# Start 62 processes for cracking mixalpha-numeric equal to 6 digits
eval echo\ {A..Z}AAAAA\; | xargs -I % -P 26 fcrackzip -c Aa1 -b -p % --verbose -u $targetfile >> $logfile &
eval echo\ {a..z}AAAAA\; | xargs -I % -P 26 fcrackzip -c Aa1 -b -p % --verbose -u $targetfile >> $logfile &
eval echo\ {0..9}AAAAA\; | xargs -I % -P 10 fcrackzip -c Aa1 -b -p % --verbose -u $targetfile >> $logfile &

tail -F $logfile | grep FOUND

by the way this doesnt work. if you run line 8 and look at top it just spawns 26 threads doing the same things meaning AAAAAA 26 processes, BAAAAA 26 processes, etc...
