Performing Advanced File Comparison with the FC Utility
The FC utility is a slightly advanced form of the Comp utility described in an earlier section. You
can use it for the same types of activities, but perform a more flexible comparison of the two files.
For example, this utility has a comparison mode specifically designed for binary files. This utility
uses the following syntax (the first is for ASCII files; the second is for binary files):
FC [/A] [/C] [/L] [/LBn] [/N] [/OFF[LINE]] [/T] [/U] [/W] [/nnnn]
[drive1:][path1]filename1 [drive2:][path2]filename2
FC /B [drive1:][path1]filename1 [drive2:][path2]filename2
The following list describes each of the command line arguments.
/A Displays only the first and last lines for each set of differences. Normally, the FC utility (like
the Comp utility) displays every line for a set of differences, making the output difficult to read
when the files have a lot of differences.
/B Performs a binary comparison of the two files. This means that the FC utility won??™t interpret
control characters such as linefeed, carriage return, and end of file character (ASCII character
26) as it would when performing an ASCII comparison.
