Power Need help in assigning output of n commands to n variables automatically inside a for loop
Please help me to automatically assign the output of awk command to the variables cs3, cs4, cs5 and cs6 using a for loop. The below code is not working.

Code:
for i in 3 4 5 6
do
        cs$i=`awk -F"|" 'BEGIN{sum=0}{sum=sum+$'$i'}END{printf("%d\n", sum)}' css`
done
echo $cs3 $cs4 $cs5 $cs6

Before I even attempt this, is it possible to grep for a pattern, maybe a partial sentence like "go to page 3", assign that to a variable and then use awk or something to pull out the 3 and assign it to a variable? So first I would have Gotopg = "go to page 3" then page = 3 (9 Replies)

sum

sum(1B) 					     SunOS/BSD Compatibility Package Commands						   sum(1B)

NAME

       sum - calculate a checksum for a file

SYNOPSIS

       /usr/ucb/sum file...

DESCRIPTION

       sum  calculates	and  displays a 16-bit checksum for the named file and displays the size of the file in kilobytes. It is typically used to
       look for bad spots, or to validate a file communicated over some transmission line. The checksum is calculated by an  algorithm	which  may
       yield different results on machines with 16-bit ints and machines with 32-bit ints, so it cannot always be used to validate that a file has
       been transferred between machines with different-sized ints.

USAGE

       See largefile(5) for the description of the behavior of sum when encountering files greater than or equal to 2 Gbyte ( 2^31 bytes).

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWscpu			   |
       +-----------------------------+-----------------------------+

SEE ALSO

       sum(1), wc(1), attributes(5), largefile(5)

DIAGNOSTICS

       Read error is indistinguishable from EOF on most devices; check the block count.

NOTES

       sum and /usr/bin/sum (see sum(1)) return different checksums.

       This utility is obsolete.
