linux - modifying a time lapse bash script for raspberry pi - crashes before 10 Am -


i got bash script online uses raspberry pi's camera module take photos @ specified rate specified timeframe. can't seem run script before 10 because can't add timeframe time (in 24 hour) because has 0 in front of number. tried adding # in front of variable other posts said pi spits out syntax error. i'm new bash.

code:

#!/bin/sh  if [ ! -n "$3" ]     echo ""     echo "\033[1;31musage: tl <interval (in seconds)> <duration (in hours)> <duration (in minutes)>"     echo ""     echo "\033[1;32mexample: tl 10 5 30"     echo "(takes picture every 10 seconds next 5 hours , 30 minutes)"     echo "\033[0m"  elif  [ ! -d /mnt/usb/tl_storage/pics_$(date +%f) ]     sudo mkdir -p /mnt/usb/tl_storage/pics_$(date +%f)     interval=$(($1 * 1000))     duration=$((($2 * 60 + $3) * 60000))     hour_act=$(date +%h)     minute_act=$(date +%m)     hour_tmp=$(($hour_act + $2))     minute_tmp=$(($minute_act + $3))     if [ "$hour_tmp" -gt 24 ]             hour_then=$(($hour_tmp - 24))     else         hour_then=$hour_tmp     fi     if [ "$minute_tmp" -gt 60 ]             minute_then=$(($minute_tmp -60))         hour_then=$((hour_then + 1))     else         minute_then=$minute_tmp     fi     echo "\033[1;31mtaking pictures timelapse in progress. check @ $hour_then:$minute_then"     echo "\033[0m"     cd /mnt/usb/tl_storage/pics_$(date +%f)/     sudo raspistill -o lapse_%04d.jpg -tl $interval -t $duration     cd $home else     interval=$(($1 * 1000))     duration=$((($2 * 60 + $3) * 60000))     hour_act=$(date +%h)     minute_act=$(date +%m)     hour_tmp=$(($hour_act + $2))     minute_tmp=$(($minute_act + $3))     if [ "$hour_tmp" -gt 24 ]             hour_then=$(($hour_tmp - 24))     else         hour_then=$hour_tmp     fi     if [ "$minute_tmp" -gt 60 ]             minute_then=$(($minute_tmp -60))         hour_then=$((hour_then + 1))     else         minute_then=$minute_tmp     fi     echo "\033[1;31mtaking pictures timelapse in progress. check @ $hour_then:$minute_then"     echo "\033[0m"     cd /mnt/usb/tl_storage/pics_$(date +%f)/     sudo raspistill -o lapse_%04d.jpg -tl $interval -t $duration     cd $home fi

command:
