174 MS-DOS User's Reference
If both the /w and /c options are specified, then FC compresses
white space and ignores case. For example, if an underscore
represents a white space, then the following two lines match:
/
\
DATA_was_found
data_was_found
^ )
The /L switch compares the files in ascii mode. This switch is the
default when you compare files that do not have extensions of
^
)
.exe, .com, .sys, .obj\ .lib, or .bin.
The /Lb switch sets the internal line buffer to n lines. The default
length of the internal buffer is 100 lines. Files that have more
K
than this number of consecutive, differing lines will abort the
comparison.
The /n switch displays the line numbers on an ascii comparison.
The /t switch does not expand tabs to spaces. The default is to
treat tabs as spaces to 8-column positions.
The /w switch causes FC to compress white space (tabs and
spaces) during the comparison. If a line contains several spaces or
tabs in a row, these characters are considered a single white
space.
Note that although FC compresses white space, it does not ignore
it. The exception is beginning or ending white space in a line,
which is ignored. For example, of the next four examples, the first
three match, but the fourth does not (note that an underscore
represents a white space):
More
data_to_be_found
More_data_to_be_found
t
)
.m
More
data_to_be
found
Moredata_to_be_found
The /nnnn switch specifies the number of lines that must match
after FC finds a difference between files. If the number of match-
ing lines in the files is less than this number, FC displays these
matching lines as differences.
