File Comparison Utility (FC) 173
FC would take reportl.txt in the \user\pete directory of disk
drive C and compare it with the corresponding reportl.txt in the
\user\betty directory. It would then compare Pete's report2.txt
against Betty's, and, finally, compare their report^, txt files.
Since in this example no drive was specified for the second set of
files, FC would have assumed that the \user\betty directory was
on the disk in the default drive.
FC Switches Using switches with
r^ FC
1 There are nine switches that you can use with the File Com
parison utility. They are described in the following paragraphs.
>—k The /a switch abbreviates the output of an ascii comparison.
' Instead of displaying all of the lines that are different, only the
lines that begin and end each set of differences are displayed.
^.^^ The intermediate lines are represented by ellipses (...).
The /b switch forces a binary comparison of both files. The two
files are compared byte by byte, with no attempt to resynchronize
^^ after a mismatch. The mismatches are printed as follows:
xxxxxxxx yy zz
(where xxxxxxxx is the relative address of the pair of bytes from
the beginning of the file). Addresses start at 00000000; yy and zz
/tm. are the mismatched bytes from file1 and file2, respectively. If one
( > of the files contains less data than the other, a message is dis
played. For example, \ifilel.txt ends beforefile2.txt, FC displays:
(~*} fc: file2.txt longer than file1.txt
This switch is the default when you compare .exe, .com, .sys, .obj,
f^ .lib, or.bin files.
The /c switch causes the matching process to ignore the case of
letters. All letters in the files are considered uppercase letters. For
/*"*^ example, the following two lines would be considered matching:
Much MORE data IS NOT FOUND
' ' much more data is not found
n
