BZNEW(1) General Commands Manual BZNEW(1) NAME
bznew - recompress .gz or .tgz files to .bz2 files SYNOPSIS
bznew [ -ftv9PK] [ name.gz ... ] DESCRIPTION
Bznew recompresses files from .gz (gzip) format to .bz2 (bzip2) format. If you want to recompress a file already in bzip2 format, rename the file to force a .bz2 extension then apply bznew. OPTIONS
-f Force recompression from .gz to .bz2 format even if a .bz2 file already exists. -t Tests the new files before deleting originals. -v Verbose. Display the name and percentage reduction for each file compressed. -9 Use the slowest compression method (optimal compression). -P Use pipes for the conversion to reduce disk space usage. -K Keep a .gz file when it is smaller than the .bz2 file SEE ALSO
bzip2(1), gzip(1) BUGS
Bznew does not maintain the time stamp with the -P option if cpmod(1) is not available and touch(1) does not support the -r option. BZNEW(1)
