# Linux bzip2 Command [ Linux Command Manual](#) The Linux bzip2 command is used to compress files. Similar to gzip, bzip2 provides better compression ratios by using a more efficient compression algorithm (Burrows-Wheeler algorithm), but the compression speed is usually slightly slower. ### Syntax bzip2 [file...] * `file...`: The file(s) to compress. `bzip2` will compress the specified file(s), generate a compressed file with a `.bz2` suffix, and delete the original file(s). **Common options**: * `-d`: Decompress a `.bz2` file. Equivalent to using the `bunzip2` command. * `-k`: Keep the original file, do not delete it. * `-v`: Display detailed compression or decompression process. * `-z`: Force compression even if the file is already compressed. * `-t`: Test the integrity of the compressed file. * `-1` to `-9`: Specify the compression ratio. `-1` is the fastest compression with the lowest compression ratio; `-9` is the slowest compression with the highest compression ratio. The default is `-9`. ### Examples **Compress a file** bzip2 example.txt This command will compress `example.txt` into `example.txt.bz2` and delete the original file `example.txt`. **Keep the original file** If you want to keep the original file after compression, you can use the `-k` option: bzip2 -k example.txt This command will keep the original `example.txt` file and generate `example.txt.bz2`. **Decompress a file** To decompress a `.bz2` file, you can use the `-d` option or directly use `bunzip2`: bzip2 -d example.txt.bz2 or bunzip2 example.txt.bz2 This will decompress `example.txt.bz2` back to the original `example.txt` file. **Test a compressed file** You can use the `-t` option to test the integrity of a compressed file: bzip2 -t example.txt.bz2 If the file is intact and not corrupted, this command will produce no output; otherwise, it will prompt an error.
