The

bzcmp

utility is used to invoke the

cmp

utility on bzip2 compressed files. All options specified are passed directly to

cmp

. As internally

bzcmp

calls

cmp

, We can pass the

cmp

command options to

bzcmp

If only one file is specified, then the files compared are file1 and an uncompressed file1.bz2.
If two files are specified, then they are uncompressed if necessary and fed to cmp.

Syntax:

bzcmp [cmp_options] file [file]

Example 1:

Comparing two files as follows:

In the above example, bzcmp compares the

file1.bz2

and

file2.bz2

and returns the first-byte position where the data differs.

Example 2:

Here, we will use

bzcmp

with Single parameter. Edit the compressed file

file1.bz2

and replace the content from "

GeeksForGeeks bzcmp example file1.

" to "

GeeksForGeeks bzcmp example file1 changed.

" and execute the following command. bzcmp utility compares the

file1.bz2

and file1.

Note:

The output from

cmp

refers to temporary file name instead of a specified filename. To check the difference of contents in compressed(bz2) files you can use

command.
