Working with compression utilities Tar, Gzip, Bzip2, Zip ...

## Use of Tar, Gzip, Bzip2, Zip ##

========================

gzip & gunzip:

----------------

gzip - compresses files

gunzip - decompresses gzip files

How to compress 'seq.txt' file using gzip,

#gzip <source file> <Sourcefile.gz>

#gzip seq.txt seq.txt.gz OR

#gzip -c seq.txt > seq.txt.gz (gzip will redirect this file to seq.txt.gz file)

How to uncompress 'seq.txt' file using gunzip,

        #gunzip seq.txt.gz - dumps to file, and removes compressed version

bzip2 & bunzip2:

------------------

bzip2 - compresses files

bunzip2 - decompresses .bz2 files

How to compress 'seq.txt' file using bzip2,

#bzip2 <source file> <Sourcefile.bz2>

#bzip2 seq.txt seq.txt.bz2 OR

#bzip2 -c seq.txt > seq.txt.bz2 (bzip2 will redirect this file to seq.txt.bz2 file)

How to uncompress 'seq.txt' file using bunzip2,

        #bunzip2 seq.txt.bz2 - dumps to file, and removes compressed version

zip & unzip:

-------------

#zip seq.zip <Folder name to compress>

#zip seq.txt.zip seq.txt

To unzip a file or folder,

#unzip seq.txt.zip

tar with gzip/bzip2:

---------------------

To compress:

#tar -cvf filename.tar /root/test/ (creates a non-compressed archive of a folder /root/test)

  #tar -cvf seq.txt.tar seq.txt (Creates tar file)

#tar -czvf seq.txt.tar.gz seq.txt (creates tar/gzip file)

#tar -cjvf seq.txt.tar.bz2 seq.txt (creates tar/bzip2 file)

#tar -cjvf seq.txt.tar.bz2 seq.txt /root  (creates tar/bzip2 file for the text file and '/root' directory tree)

To extract files:

#tar -xvf filename.tar

#tar -zxvf filename.tar (To uncompress file tarred with gzip or bzip2)
