You ask about comparing files after a certain number of characters, so are you looking to ignore a fixed number characters on each line for each file?
If those are the 'true' files, then a solution could be proposed.
However, if there is more to the samples, it would be helpful to see.
The files contain more than 1 line, a more likely example would be:
file1:
lalalala good file
lalblala good file
lalalalb good file
lalalbla good file
file2:
lblblblb good file
lblblclb good file
lblclblb good file
lclblblb good file
compare:
#file1 and file2 are the same
so I want to start compare after say 8 characters on every line in the two files.

I need to compare File A with File B and create FILE C with the difference record only. What I mean is File A has 3 records and File B has 4 records, so FILE C will only have 1 record (becuase that record is in FILE B and not in File A). Hope I am making sense. The data layout is that each data... (7 Replies)

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.
