• to extract, be lazy, use unp, it does all the syntax for you.
    unp filename.tar.7z.rar.gz

    unp is available on repository apt-get install unp

  • To group multiple files :
    tar -cvf foo.tar a.dat b.dat c.dat

    ( this will group files [a-c]*.dat to one file foo.tar )

c = create a tar file
v = verbose( nothing important :P )
f = create the tar file with filename provided as the argument
Thats all you need to know to tar(group) a bunch of files/directories.

  • To tar files and gzip them :
    tar -czf foo.tar.gz *.dat

    ( this will create a gzip-compressed Tar file of the name foo.tar.gz of all files with a .dat suffix in that directory )

  • To untar(separate) files from a tar archive :
    tar -xvf foo.tar

    ( this will produce three separate files a.dat, b.dat and c.dat )

  • To untar(extract) a gzipped tar archive file :
    tar -xzf foo.tar.gz
  • To untar a bzipped (.bz2) tar archive file :
    tar -xjf foo.tar.bz2

slicing files can also be useful More info for beginners. I accomplished the above process successfully with these commands:

tar'ed the file with: nohup nice tar -cf /foo.bu.tar /fooSource &

split the file into 500MB chunks with: nohup nice split –line-bytes=500m foo.tar.gz foo_ &

rejoined the file with: nohup nice cat foo_a* > foo_FULL.tar.gz &

hope it works for you too…

BTW, the nohup, nice and '&' are just for running the contained command considerately in the background of my terminal window because the processes took so long.
