echo $n
exit

When you make sure the value is correct you can then remove the exit

Now you have to fix your code so that is handle the case of months that only have 30 days ... or 28 days ... or leap year ! Smilie

So sorry..I faced to a little problem. Basically everything is working...but 2013101008 is the maximum number which works in code... it says in error that value is too great for base ("error token is 08").
basically problem with the format...i need all numbers from 01 01 to 099 100 in this format. But in this code i just put 0 in front of number when print it.
Can i transform number before statements in the beginning of the code or smth like that?

Code:
#!/bin/bash --posix
# Apple Macbook Pro 13", circa 10-08-2012, OSX 10.7.5, default bash terminal.
# 
# Now obtain any date and add 00 to 099 at the end.
# It is simple to add the last 100 after every day.
# You may have to change pieces to suit you environment and OS etc...
for newdate in {0..365}
do
	# Get epoch time and use IT to do all of the hard work...
	secs=$(date +"%s")
	secs=$[ ( ( ( $secs / 86400 ) * 86400 ) + ( $newdate * 86400 ) ) ]
	for n in {0..99}
	do
		# Date WITH spaces...
		# currentdate=$(date -r $secs +"%Y %m %d")
		# Date WITHOUT spaces...
		currentdate=$(date -r $secs +"%Y%m%d")
		data="0$n"
		# Result WITH spaces...
		# currentdate="$currentdate $data"
		# Result WITHOUT spaces...
		currentdate="$currentdate$data"
		echo "$currentdate"
	done
done
# Now all you have to do is add your I/O and any comparing parts...

This will print a whole years worth of dates with extensions of 00 to 099 to STDOUT.

I got the idea, thanks. You helped me a lot. But my last numbers goes only until 09 and then it starts from 02 again. Why? it does not reach even 100 for incrementing days or months.... Sorry just I try to do my best to fix code but I am not good at programming I guess....

Code:
if [ -f "kuku.txt" ]
     then

n=$(sort /Users/Natalie/1/kuku.txt | tail -1)
fourthoct=${n:0:4}
thirdoct=${n:4:2}
secondoct=${n:6:2}
firstoct=${n:8:2}

  wardevent=$(expr $firstoct + 0);
  if [ ! $((++wardevent)) -eq 100 ]
                 then
                      data="0$wardevent"
                  else
                    firstoct=0
                    data="0$firstoct"
                   if [ $((++secondoct)) -eq 32 ]
                         then
                        secondoct=0
                         if [ $((++thirdoct)) -eq 13 ]
                               then
                                thirdoct=0
                                   ((++fourthoct))

fi
fi
fi

printf  $fourthoct$thirdoct$secondoct$data > '/Users/Natalie/1/kuku.txt'
      else
echo ` date +%Y%m%d`"00" >'/Users/Natalie/1/kuku.txt'
fi

Couple of things to not the shell treats numbers with leading zero as octal so you need strip leading zero off before doing any maths on them, this is why when you reach 08 things started to break.

Also let printf do the heavy lifting for you, it can format with leading zeros automatically


Try this:

Code:
if [ -f "/Users/yerlanrsaldin/1/kuku.txt" ]
then
  n=$(sort /Users/yerlanrsaldin/1/kuku.txt | tail -1)

  fourthoct=${n:0:4}
  thirdoct=${n:4:2}
  thirdoct=${thirdoct#0}
  secondoct=${n:6:2}
  secondoct=${secondoct#0}
  firstoct=${n:8:2}
  firstoct=${firstoct#0}

  if [ $((++firstoct)) -eq 100 ]
  then
      firstoct=0
      if [ $((++secondoct)) -eq 32 ]
      then
          secondoct=0
          if [ $((++thirdoct)) -eq 13 ]
          then
              thirdoct=0
              ((++fourthoct))
          fi
      fi
  fi
  
  printf  "%04d%02d%02d%02d\n" $fourthoct $thirdoct $secondoct $firstoct > '/Users/yerlanrsaldin/1/kuku.txt'
else
  echo ` date +%Y%m%d`"00" >'/Users/yerlanrsaldin/1/kuku.txt'
fi
