cmp in Mac OS X
By: Strauss K in macos Tutorials on 2011-02-03
cmp is a command-line utility used in Unix-based operating systems, including Mac OS X, to compare two files byte by byte. The cmp command is useful for verifying that two files have the same content, or for finding the location of differences between two files.
To use cmp, open the Terminal application and navigate to the directory where the two files that you want to compare are located. Then, use the following command:
cmp file1 file2
Replace "file1" and "file2" with the names of the two files that you want to compare. The cmp command will display the location of the first byte where the two files differ, if there is a difference. If there is no difference, the cmp command will not display any output.
For example, if you want to compare two files named "example1.txt" and "example2.txt", you would use the following command:
cmp example1.txt example2.txt
After running this command, the cmp command will display the location of the first byte where the two files differ, if there is a difference. If there is no difference, the cmp command will not display any output.
