ksh scripting SSH to Compare File Sizes
Hello,
I currently have very little experience with Shell scripting and trying to create a script for the purpose of collecting the size of a couple sizes on 4 different Hosts. The Idea is to collected the information from the files in which the script is kicked off on, store the values into Variables, SSH to the next Host and repeat for the remaining 2. With Variables Collected I would like to compare the sizes and output that they matched.

This is what I have come up with so far but not the most familiar with constructs and especially the SSH Process.

Code:
#!/bin/ksh

FILENAME1=/root/directory1/files/file1.fil
FILE1SIZEa=$(stat -c%s "$FILENAME1")

FILENAME2=/root/directory2/files/file2.fil
FILE2SIZEa=$(stat -c%s "$FILENAME2")

ssh user@server2 |

FILENAME3=/root/directory1/files/file1.fil
FILE1SIZEb=$(stat -c%s "$FILENAME3")

FILENAME4=/root/directory2/files/file2.fil
FILE2SIZEb=$(stat -c%s "$FILENAME4")

ssh user@server3 |

FILENAME5=/root/directory1/files/file1.fil
FILE1SIZEc=$(stat -c%s "$FILENAME5")

FILENAME6=/root/directory2/files/file2.fil
FILE2SIZEc=$(stat -c%s "$FILENAME6")

ssh user@server4 |

FILENAME7=/root/directory1/files/file1.fil
FILE1SIZEd=$(stat -c%s "$FILENAME7")

FILENAME8=/root/directory2/files/file2.fil
FILE2SIZEd=$(stat -c%s "$FILENAME8")


if && [[ "$FILE1SIZEa" =~ ^($FILE1SIZEb|$FILE1SIZEc|$FILE1SIZEd)$ ]]; then
	print "FILE1 Sizes Match"
else
	print "Something is Wrong with FILE1"
fi

if && [[ "$FILE2SIZEa" =~ ^($FILE2SIZEb|$FILE2SIZEc|$FILE2SIZEd)$ ]]; then
	print "FILE2 Sizes Match"
else
	print "Something is Wrong with FILE2"
fi

If someone could help get this functioning, or possibly has suggestions for more efficient scripting with less repetition It would be greatly appreciated.


Thanks for your consideration.

lzcmp

XZDIFF(1)							     XZ Utils								 XZDIFF(1)

NAME

       xzcmp, xzdiff, lzcmp, lzdiff - compare compressed files

SYNOPSIS

       xzcmp [cmp_options] file1 [file2]
       xzdiff [diff_options] file1 [file2]
       lzcmp [cmp_options] file1 [file2]
       lzdiff [diff_options] file1 [file2]

DESCRIPTION

       xzcmp  and  xdiff invoke cmp(1) or diff(1) on files compressed with xz(1), lzma(1), gzip(1), or bzip2(1).  All options specified are passed
       directly to cmp or diff.  If only one file is specified, then the files compared are file1 (which must have a suffix of	a  supported  com-
       pression  format)  and  file1 from which the compression format suffix has been stripped.  If two files are specified, then they are uncom-
       pressed if necessary and fed to cmp(1) or diff(1).  The exit status from cmp or diff is preserved.

       The names lzcmp and lzdiff are provided for backward compatibility with LZMA Utils.

SEE ALSO

       cmp(1), diff(1), xz(1), gzip(1), bzip2(1), zdiff(1)

BUGS

       Messages from the cmp(1) or diff(1) programs refer to temporary filenames instead of those specified.
