diff -- Compare two files

diff [-bdefh] [-c symbol] file1 file2

Options:
     -b        Ignore trailing blanks; all strings of blanks are equal
     -c sym    Make cpp input conditionalized on sym
     -d        Use -h algorithm for large (>25,000 character) files
     -e        Make ed script
     -f        Make fake (non-usable) ed script
     -h        Half-hearted algorithm (works on long files)
     -s        Make sed script

If either file1 or file2 is `-', stdin is used.  If one file is a directory,
the other file under that directory is used.
