gzip 2 files into one file












6














I want to gzip two or more files into one file, I checked this and this but both have files like: n1.txt, n2.txt, ... but my filenames are completely different, like: file.mp4, bar.txt, foo.jpeg and I want to gzip them all and put the output into one file. This didn't help too:



gzip -c file.mp4 > test.gz

gzip -c bar.txt >> test.gz


Do I have to tar them first?



And another question: In tar files, we can watch inner files without decompression using:



tar -tvf filename.tar


Is there anyway to do this with gzip or bzip2?






command-line tar gzip bzip2

          Unlike ZIP, RAR or 7-Zip, for example, gzip can only compress one file. As you’ve already noted, there is the tar program which can serialize multiple files into one which makes them ready for gzip. The traditional Unix philosophy prefers to use multiple simpler and more specialized tools than one monolithic and complicated. In this case, it results in using tar and gzip consecutively, resulting in a .tar.gz (or .tgz) file.



          However, GNU tar includes the -z option which compresses the result of the traditional tar using gzip in just one command.



          .tar.gz files are mostly created using the -czvf options:





          • create a new archive

          • gzip (alternatives: j for bzip2, J for xz)


          • verbose (list processed files; optional)

          • output file (the following argument specifies the output file)


          In your example, you can use the command:



          tar -czvf test.tar.gz file.mp4 bar.txt




          Is there any way to watch inner files without decompression with gzip or bzip2?




          Yes, your command also works for a .tar.gz file:



          tar -tvf test.tar.gz

            The combination of two tools has also allowed the replacement of the compression method with others more efficient for a specific need. Modern versions of tar knows many compressors and can transparently invoke them when needed.

            Little known fact: It is possible to compress multiple files with gzip. But it's not very useful since when decompressing such a file with gunzip it will just append all the original files into a single file. If you type echo Foo > a ; gzip a you will have a file called a.gz which contains both the name and timestamp of the original a file. If you then type echo Bar > b ; gzip b ; cat a.gz b.gz >combined.gz you will have a combined.gz file which contains all the information needed to reconstruct a and b with their original names, contents, and timestamps.

          gzip is a compressor, not an archiver, but it works well with tar



          tar -cvzf file.tar.gz path-to-files-or-directories-to-compress


          See man tar



          Compression options
          
   -a, --auto-compress
          
          Use archive suffix to determine the compression program.
          

          
   -I, --use-compress-program=COMMAND
          
          Filter data through COMMAND.  It must accept the -d option,  for
          
          decompression.  The argument can contain command line options.
          

          
   -j, --bzip2
          
          Filter the archive through bzip2(1).
          

          
   -J, --xz
          
          Filter the archive through xz(1).
          

          
   --lzip Filter the archive through lzip(1).
          

          
   --lzma Filter the archive through lzma(1).
          

          
   --lzop Filter the archive through lzop(1).
          

          
   --no-auto-compress
          
          Do not use archive suffix to determine the compression program.
          

          
   -z, --gzip, --gunzip, --ungzip
          
          Filter the archive through gzip(1).
          

          
   -Z, --compress, --uncompress
          
          Filter the archive through compress(1).



          And yes, you can watch compressed archives the same way.

But it's not very useful since when decompressing such a file with gunzip it will just append all the original files into a single file. If you type echo Foo > a ; gzip a you will have a file called a.gz which contains both the name and timestamp of the original a file. If you then type echo Bar > b ; gzip b ; cat a.gz b.gz >combined.gz you will have a combined.gz file which contains all the information needed to reconstruct a and b with their original names, contents, and timestamps.

            Little known fact: It is possible to compress multiple files with gzip. But it's not very useful since when decompressing such a file with gunzip it will just append all the original files into a single file. If you type echo Foo > a ; gzip a you will have a file called a.gz which contains both the name and timestamp of the original a file. If you then type echo Bar > b ; gzip b ; cat a.gz b.gz >combined.gz you will have a combined.gz file which contains all the information needed to reconstruct a and b with their original names, contents, and timestamps.

            gzip is a compressor, not an archiver, but it works well with tar



            tar -cvzf file.tar.gz path-to-files-or-directories-to-compress


            See man tar



            Compression options
            
   -a, --auto-compress
            
          Use archive suffix to determine the compression program.
            

            
   -I, --use-compress-program=COMMAND
            
          Filter data through COMMAND.  It must accept the -d option,  for
            
          decompression.  The argument can contain command line options.
            

            
   -j, --bzip2
            
          Filter the archive through bzip2(1).
            

            
   -J, --xz
            
          Filter the archive through xz(1).
            

            
   --lzip Filter the archive through lzip(1).
            

            
   --lzma Filter the archive through lzma(1).
            

            
   --lzop Filter the archive through lzop(1).
            

            
   --no-auto-compress
            
          Do not use archive suffix to determine the compression program.
            

            
   -z, --gzip, --gunzip, --ungzip
            
          Filter the archive through gzip(1).
            

            
   -Z, --compress, --uncompress
            
          Filter the archive through compress(1).



            And yes, you can watch compressed archives the same way.
