TGZ
From Wikipedia, the free encyclopedia.
A
tgz or
tar.gz file is a
compressed archive of directories
and/or files that is prepared by
tarring a directory, and then gzipping the resulting .tar file.
In Linux it's used:
- To pack the command
- Simple tar file: tar -cf packedfiles.tar filetopack1 filetopack2 and so on...
- to pack and compress:
- tar -czf packedfiles.tgz filetopack1 filetopack2 and so on...to compress in gzip
- and tar -cjf packedfiles.tgz filetopack1 filetopack2 and so on...to compress in bzip2 file format.
- To unpack tar files
- and uncompress gziped files, the command tar -xzf filetounpack.tar.gz
- and uncompress bzip2ed files, tar -xjf filetounpack.tar.gz.bz2
tar and gzip are available on other operating systems, although the functionality of tar can be different. On a standard
Sun Solaris system, for instance, users can't use the
j or
z arguments on a tar
command line to automatically compress the file into bzip2 or gzip format. The decompression and expansion must be broken down into two separate steps, although it is possible to use the
Unix pipe capability to combine the two steps manually. However, it is possible to install the
GNU version of tar on most systems that have this deficiency.
- To pack
- One step at a time
- tar -cf packedfiles.tar filetopack1 filetopack2 ...
- gzip packedfiles.tar
- All at once
- tar -cf - filetopack1 filetopack2 ... | gzip -c > packedfiles.tar.gz
- To unpack
- One step at a time
- gunzip packedfiles.tar.gz
- tar -xf packedfiles.tar
- All at once
- gunzip -c packedfiles.tar.gz | tar -xf -
