how canI subtact two number that have been calculated by foreach? I try but it hang?!

[alivip]

I have try by this code

echo "" > outputISP 
echo "" > outputISP2
    
foreach priod ( 720 580 360 270 120 90 )
 foreach priod2 ( 580 360 270 120 90  0)
          
set fsize = `find  -mtime -${priod} -type f | xargs ls -tg | awk '{ size += $4 } END {print size}' `
set fsize2 = `find  -mtime -${priod2} -type f | xargs ls -tg | awk '{ size2 += $4 } END {print size2}' `
set defsize = `awk '{ defsize = fsize - fsize2 } END {print defsize}' `
	  
echo "  ${priod}  ${fsize}" >> outputISP
echo "  ${priod2}  ${defsize}" >> outputISP2
end
end	  
	  
more outputISP2

but it hang

I wont to calculate "fsize" each of "priod" and calculate "fsize2"of each "priod2"
and subtract sequentially each result of "fsize" - "fsize2"
for example first number of "priod" is 720 and first number of "priod2" is 580 and
calculate size of 720 =900000 and size of 580=800000
the result should be 900000 - 800000=100000

by the way “fsize” and fsize2 calculate the Data size growth of file from number period witch is "priod" and "priod2"

alivip,

Please post your code in code tags and try to spell, punctuate, and capitalize correctly to improve readability.

Ok, I think this line isn't proper:

set defsize = `awk '{ defsize = fsize - fsize2 } END {print defsize}'`

I'm not familiar with csh but I think your loop should look like this:

foreach priod ( 720 580 360 270 120 90 )
  foreach priod2 ( 580 360 270 120 90 0)
    set fsize = `find -mtime -${priod} -type f | xargs ls -tg | awk '{ size += $4 } END {print size}'`
    set fsize2 = `find -mtime -${priod2} -type f | xargs ls -tg | awk '{ size2 += $4 } END {print size2}'`
    set defsize = $fsize - $fsize2
    echo " ${priod} ${fsize}" >> outputISP
    echo " ${priod2} ${defsize}" >> outputISP2
  end
end

it does not solve the problem
it hang same as before

I do this modification

 
set index = 1
    set limit = `expr $#values - 1`
    while ($index <= $limit)
	set value = $values[$index]
	echo $value
	
	# calculate the size of files within a specific period:
	set fsize = `find  -mtime -$value -type f | xargs ls -tg | awk '{ size += $4 } END {print size}'`
        
	# for testing:
	echo $fsize
	
	# calculate the next index:
	set nextIndex = `expr $index + 1`
	
	set value = $values[$nextIndex]
	echo $value
	
	# calculate the size of files within the next specific period:
	set fsize2 = `find  -mtime -$value -type f | xargs ls -tg | awk '{ size2 += $4 } END {print size2}' `
	
	# for testing:
	echo $fsize2
	
	# calculate the difference:
	set defsize = `expr $fsize - $fsize2`
	
	# for testing:
	echo defrance
	
	# for testing:
	echo $defsize
	
	# write into file:
	echo "  $values[$index]  ${defsize}" >> outputISP2
	
	# update index:
	set index = `expr $nextIndex`
	
	echo "------------------------------"
	echo $index
	echo "------------------------------"
    end

give the result correct but for just 2 of 6 of array (720 ,580 ) but the other give dash "-"

and error message
"xargs: unmatched single quote"
