Understanding a diff file
Hi folks,
I am having difficulties in understanding diff file.
I would like to know what the following means in a diff file
ex:
202a251,253
1,102c120,126
I believe 'a' will be 'append'. Line 202 appended to line 251. but why there is 253 ???.
Like the above if any one can tell me how to understand these, it will be helpful.
Any links to useful websites that explains how to interpret diff file will be also enough. thanks.

BZDIFF(1) General Commands Manual BZDIFF(1) NAME
bzcmp, bzdiff - compare bzip2 compressed files SYNOPSIS
bzcmp [ cmp_options ] file1 [ file2 ] bzdiff [ diff_options ] file1 [ file2 ] DESCRIPTION
Bzcmp and bzdiff are used to invoke the cmp or the diff program on bzip2 compressed files. All options specified are passed directly to cmp or diff. If only 1 file is specified, then the files compared are file1 and an uncompressed file1.bz2. If two files are specified, then they are uncompressed if necessary and fed to cmp or diff. The exit status from cmp or diff is preserved. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +--------------------+-----------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +--------------------+-----------------+ |Availability | SUNWbzip | +--------------------+-----------------+ |Interface Stability | Committed | +--------------------+-----------------+ SEE ALSO
cmp(1), diff(1), bzmore(1), bzless(1), bzgrep(1), bzip2(1) BUGS
Messages from the cmp or diff programs refer to temporary filenames instead of those specified. BZDIFF(1)
