Linux/Unix for file handling

For any computational biologist linux/unix is the beautiful operating system for data analysis. I am discussing here few basic commands for file handling.

LINUX COMMANDS:

1.  Commands for bundling and compressing the files

     tar -cvf files.tr file1 file2 file3  (File names, Output: files.tar)               

     gzip files.tr                                  (For compressing, Output: files.tar.gz)

     For supercompression

      bzip2 files.tar               (For super compression Output: files.tar.bz2)

        bzip2 file                                              (Output: file.bz2)

2. Unzipping

    tar - zxvf files.tar.gz         (Direct unzipping, Output: you will get all files)

      gunzip files.tzr.gz                  (First step: unzip the gz file, Output: files.tr)

      tar -xvf files.tr                       (Second step: untar, Output: all files)

      For supercompressed files

     bunzip2 files.tar.bz2         (Output: files.tar, tar -xvf for open the bundle)

      tar -xjvf files.tar.bz2         (Direct, Output: all files)
