Full Discussion: ksh scripting SSH to Compare File Sizes

I appreciate the advice, I was kind of thinking the same thing myself while looking at it that I needed some sort of for loop to iterate through the servers executing the same command while storing file locations in variables and simply comparing each server to the 1st. I don't really have any idea of how i could apply a for loop to ssh multiple servers that were in an Array for instance. Though I did rework the code a bit and came up with the following solution, though you couldn't be as specific in your output you could easily spot an error.

Code:
#!/bin/ksh


FILE1=/root/directory1/files/file1.fil
FILE2=/root/directory2/files/file2.fil
FILESZ1==$(stat -c%s "$FILE1")
FILESZ2==$(stat -c%s "$FILE2")

filecheck() {
CHKFILE1=$(stat -c%s "$FILE1")
CHKFILE2=$(stat -c%s "$FILE2")
if [[ $FILESZ1 = $CHKFILE1 ]]; then
	print "file sizes match"
else
	print "file sizes do not match"
fi
if [[ $FILESZ2 = $CHKFILE3 ]]; then
	print "file sizes match"
else
	print "file sizes do not match"
fi
}

ssh user@server2 "$(typeset -f filecheck); filecheck;
ssh user@server3 "$(typeset -f filecheck); filecheck;
ssh user@server4 "$(typeset -f filecheck); filecheck;

Would the following code do the trick or am I missing something?
Thanks for the suggestions.

COMM(1) 							   User Commands							   COMM(1)

NAME

       comm - compare two sorted files line by line

SYNOPSIS

       comm [OPTION]... FILE1 FILE2

DESCRIPTION

       Compare sorted files FILE1 and FILE2 line by line.

       When FILE1 or FILE2 (not both) is -, read standard input.

       With  no  options,  produce three-column output.  Column one contains lines unique to FILE1, column two contains lines unique to FILE2, and
       column three contains lines common to both files.

       -1     suppress column 1 (lines unique to FILE1)

       -2     suppress column 2 (lines unique to FILE2)

       -3     suppress column 3 (lines that appear in both files)

       --check-order
	      check that the input is correctly sorted, even if all input lines are pairable

       --nocheck-order
	      do not check that the input is correctly sorted

       --output-delimiter=STR
	      separate columns with STR

       --total
	      output a summary

       -z, --zero-terminated
	      line delimiter is NUL, not newline

       --help display this help and exit

       --version
	      output version information and exit

       Note, comparisons honor the rules specified by 'LC_COLLATE'.

EXAMPLES

       comm -12 file1 file2
	      Print only lines present in both file1 and file2.

       comm -3 file1 file2
	      Print lines in file1 not in file2, and vice versa.
