bzcat file1.bz2 file2.bz2 file3.bz2
Decompress with verbose output and display only the first 20 lines
bzcat -v archive.bz2 | head -n 20
Count the number of lines in a compressed file without creating an uncompressed copy
bzcat large_file.bz2 | wc -l

Notes

The bzcat command is a utility that decompresses bzip2-compressed files and sends the output to standard output. It's part of the bzip2 utilities package and is particularly useful for viewing or processing compressed files without creating intermediate uncompressed files. Key features of bzcat: 1. **Streaming Decompression**: Decompresses directly to standard output, making it ideal for pipelines and redirections. 2. **Memory Efficiency**: Allows viewing and processing compressed files without requiring disk space for the uncompressed version. 3. **File Concatenation**: Can decompress and concatenate multiple bzip2 files in a single command. 4. **Preservation of Original Files**: Unlike bunzip2, bzcat always preserves the compressed source files. Common use cases: - Viewing compressed log files without decompressing them to disk - Searching through compressed text files - Processing compressed data in pipelines - Extracting data from compressed archives to specific locations - Concatenating multiple compressed files bzcat is equivalent to running `bzip2 -dc` or `bunzip2 -c`. It's actually a symbolic link to the bzip2 program that sets specific options automatically.
