Creating archives and compress files.
zip
Available on most operating systems
- zip archive.zip file
- Create or update archive.zip, put file in there. If file is already existing in the archive it is replaced.
- zip -r archive.zip path
- Create or update archive.zip, put path and all below in there. Files existing in the archive are replaced.
- unzip archive.zip file
- Extract file from archive.zip and put it in the current directory
- unzip archive.zip path
- Extract path from archive.zip and put it in the current directory. Use quotes if path has wildcards.
- unzip -l archive.zip
- List all files in the archive.
- unzip -l archive.zip path
- List path if it is in the archive.
tar
Available on Unix-like operating systems
- tar cvf archive.tar path
- Create archive.tar and put all file under path in it. Be verbose, list what is done (-v)
- tar xvf archive.tar path
- Extract path from archive.tar, put it in the current directory. Be verbose, list what is done (-v)
- tar tf archive.tar path
- List what is in archive.tar.
- tar cvzf archive.tgz path
- Create gzipped archive.tgz and put all file under path in it. Be verbose, list what is done (-v).
- Similar for x and t, the z makes tar work on gzipped archives;
- tar uvf archive.tar --no-recursion --files-from -
- Read filenames from standard input e.g. as found by find and update the archive.
gzip
- gzip <filename>
- Compress file to <filename>.gz
- gzip -c <filename>
- Compress file to standard output. Can be used for log-rotation when the inode of the file should not change as the application keeps it open.
gzip -c <filename> > <filename>.gz; cp /dev/null <filename>
7zip
Available on most operating systems. Provides very good compression
- 7za a <archivename>.7z <files>
- Add files to archive, create it when needed.
- 7za l <archivename>.7z
- List an archive.
- 7za e <archivename>.7z <files>
- Extract <files> from archive without path, all if <files> is omitted.
- 7za x <archivename>.7z
- Extract <files> from archive with full path, all if <files> is omitted.
