Generate Regex numeric range with specific sub-ranges
hi all,

Say i have a range like 0 - 1000 and i need to split into diffrent files the lines which are within a specific fixed sub-range. I can achieve this manually but is not scalable if the range increase.

E.g

Code:
cat file1.txt
Response time 2 ms
Response time 15 ms
Response time 101 ms
Response time 279 ms
etc

What i currently do is create an array and then grep for it in a loop

Code:
bucketLimits=( 
 # 100 <> 150, 150 <> 200, 200 <> 250, 250 <> 300, 300 <> 350, 350 <> 400, 400 <> 450, 450 <> 500 
 '[1][0-4][0-9]' '[1][5-9][0-9]' '[2][0-4][0-9]' '[2][5-9][0-9]' '[3][0-4][0-9]' '[3][5-9][0-9]' '[4][0-4][0-9]' '[4][5-9][0-9]'
 # 500 <> 550, 550 <> 600, 600 <> 650, 650 <> 700, 700 <> 750, 750 <> 800, 800 <> 850, 850 <> 900, 900 <> 950, 950 <> 1000
        '[5][0-4][0-9]' '[5][5-9][0-9]' '[6][0-4][0-9]' '[6][5-9][0-9]' '[7][0-4][0-9]' '[7][5-9][0-9]' '[8][0-4][0-9]' '[8][5-9][0-9]' '[9][0-4][0-9]' '[9][5-9][0-9]' 
 )
 
  for bucketLimit in ${bucketLimits[@]}
  do
    limit=${bucketLimits[$index]}
    result=`grep "Response" file1.txt| grep -oE "time ${limit} ms" | wc -l` 
    finalResult=$finalResult","$result
    index=$(( $index + 1 ))
  done
  echo "$finalResult" >> ./stats_results.csv

Any idea how i can auto generate the buckeLimits array by giving the sub-range value? Could be 10 range or as it is now 50 range.

Thx!

SYNOPSIS

DESCRIPTION

       The following commands return a true value (exit code 0) if the a processor type matches the command name.  Otherwise a false  value  (exit
       code  nonzero)  is returned.  These commands are commonly used within makefiles and shell procedures to improve portability of applications
       (see make(1)).

EXAMPLES

       Given a shell script that must behave differently when run on an HP 9000 Series 700 or 800 system, select the correct code  segment  to	be
       executed:

WARNINGS

       always  returns	true on both Series 800 and Series 700 systems.  Therefore, when using this command in scripts to determine hardware type,
       always use both and in the appropriate sequence to ensure correct results (see

       machid(1) will no longer provide support for future machines beyond the Series 800 and Series 700 systems.  Decisions should  be  based	on
       the hardware and software configuration information returned by getconf(1).
