|CMP(1)||General Commands Manual||CMP(1)|
cmputility compares two files of any type and writes the results to the standard output. By default,
cmpis silent if the files are the same; if they differ, the byte and line number at which the first difference occurred is reported.
Bytes and lines are numbered beginning with one.
The options are as follows:
The optional arguments skip1 and skip2 are the byte offsets from the beginning of file1 and file2, respectively, where the comparison will begin. The offset is decimal by default, but may be expressed as a hexadecimal or octal value by preceding it with a leading “0x” or “0”.
cmputility exits with one of the following values:
-soption has not been specified,
cmpwrites to standard error that
EOFwas reached in the shorter file (before any differences were found).
cmputility is compliant with the IEEE Std 1003.1-2008 (“POSIX.1”) specification.
The arguments skip1 and skip2 are extensions to that specification.
cmpcommand appeared in Version 1 AT&T UNIX.
