Compare Binary Files

Syntax

os9cmp [<opts>] <path1> <path2>

Function

os9cmp opens two files and performs a comparison of the binary values of

the corresponding data bytes of the files. If any differences are

encountered, the file offset (address), the hexadecimal value, and the

ASCII character for each byte are displayed.

The comparison ends when an end-of-file is encountered on either file. A

summary of the number of bytes compared and the number of differences

found is displayed.

Examples

The following command uses an 8K buffer to compare FILE1 with FILE2.

C>os9cmp file1 file2 -b=8k
