"xargs: unmatched single quote" why this erorr message (code inside)

[alivip]

I do this

  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

it work but not properly
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"

What are the values of $value for which xargs fails? What is the find output for each of these values?

[alivip]

sorry I miss this line in the code
set values = (720 580 360 270 120 90 0)

 set values = (720 580 360 270 120 90 0)
    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 this line in the code

output of find is the size of each value (720 580 360 270 120 90 0)

Is this c shell?

[Cabhan]

No, I mean the output of just:

find  -mtime -$value -type f

Make life easier and script with bash. (This is Linux's default shell after all.)

[Cabhan]

Now that I think about it, the problem with your program may just be the C Shell, and may be entirely unrelated to the actual script.

Try rewriting your script as a Bash script and see if that fixes it.

Is this c shell?

yes it is

Try rewriting your script as a Bash script and see if that fixes it.

How?

No, I mean the output of just:
Code:

find -mtime -$value -type f

output is the files that modify in specific period of time which is $value (enter by user)

[Cabhan]

What I wanted was for you to post the exact output, as if you had run that command yourself. I know what it's supposed to output; I wanted to see what it actually output.

Anyway, to rewrite it in Bash, learn how to script in Bash. A good new user guide is:
http://tldp.org/LDP/Bash-Beginners-G...ers-Guide.html
And a fantastic advanced guide/reference is:
http://www.tldp.org/LDP/abs/html/

Most things will directly translate, it's just a matter of different syntax. Bash is basically the universal Linux shell, and as described in my link about csh scripting, has many advantages over csh for scripting.

this should be the output

I must use c shell to come with this output
