COMP + Comparing FilesCompares the contents of two files.
VERSION
PC-DOS 2.0+ (revised from 1.0)
MS-DOS equivalent: FILCOM (2.0+); COMP (1.0)
TYPE
External
SYNTAX
[d:][path] COMP [pd:][ppath][pfilename]
[sd:][spath][sfilename]
OPTIONS
[d:][path] Specifies the drive letter and
path that contain the COMP
command file.
[pd:][ppath][pfilename] Specifies the first file or
set of files that you wish to
compare (primary file).
[sd:][spath][sfilename] Specifies the second file or
set of files that you wish to
compare (secondary file).
COMP allows you to see whether two files are identical, such
as comparing a file to its backed-up version saved under a
different name.
EXAMPLE
COMP B:TEST.TXT C:TEST.TXT
compares the TEST.TXT file on drive B with the TEST.TXT file on
drive C.
MESSAGES
Compare error at offset XXXXXXXX
File 1 = YY
File 2 = ZZ
The XXXXXXXXth byte in the first file does not match the
corresponding byte in the second file. The two bytes (XX and ZZ)
are displayed in hexadecimal notation.
Compare more files (Y/N)?
Enter Y to compare additional files.
EOF mark not found
COMP could not find the end of valid data. Many text files do
not end with Ctrl-Z. The message may be innocuous.
Files are different sizes.
COMP will only compare files that are of the same size.
File sharing conflict
One of the files that is being comapred is currently being used
by another process. Try again later.
10 Mismatches- -ending compare
Ten mismatched locations were found in the compared files.
NOTE
Version 2 allows you to use the *.* wildcard pattern to
check all of the files on a disk. DISKCOMP is faster for
comparing two disks, however. In many versions of MS-DOS, the
command FILCOMP provides additional information about how files
differ. See the appropriate user's manual for manufacturer-
specific alternatives.
