NAME

bzcat- decompresses files to stdout.

SYNOPSIS

bzcat [ -s ] [ filenames ... ] 
 

DESCRIPTION

bzcat decompresses all specified files to the standard output.

(bzcat command displays the uncompressed content into standard output file for the users to view the content.)

OPTIONS

TAG DESCRIPTION
-c --stdout Compress or decompress to standard output.
-d --decompress Force decompression. bzip2, bunzip2 and bzcat are really the same program, and the decision about what actions to take is done on the basis of which name is used. This flag overrides that mechanism, and forces bzip2 to decompress.
-z --compress The complement to -d: forces compression, regardless of the invokation name.
-t --test Check integrity of the specified file(s), but don't decompress them. This really performs a trial decompression and throws away the result.
-f --force Force overwrite of output files. Default is not to overwrite. Also forces breaking of hard links to files.
-k --keep Keep (don't delete) input files during compression or decompression.
-s --small Reduce memory usage, for compression, decompression and testing. Files are decompressed and tested using a modified algorithm which only requires 2.5 bytes per block byte. This means any file can be decompressed in 2300k of memory, albeit at about half the normal speed.
-q --quiet Suppress non-essential warning messages. Messages pertaining to I/O errors and other critical events will not be suppressed.
-v --verbose show the compression ratio for each file processed. Further -v's increase the verbosity level, spewing out lots of information which is primarily of interest for diagnostic purposes.
-L --license -V --version Display the software version, license terms and conditions
-1 (or --fast) to -9 (or -best) Set the block size to 100 k, 200 k ... 900 k when compressing. Has no effect when decompressing. The --fast and --best aliases are primarily for GNU gzip compatibility. In particular, --fast doesn't make things significantly faster. And --best merely selects the default behaviour
-- Treats all subsequent arguments as file names, even if they start with a dash. This is so you can handle files with names beginning with a dash, for example: bzip2 -- -myfilename.
--repetitive-fast --repetitive-best These flags are redundant in versions 0.9.5 and above. They provided some coarse control over the behaviour of the sorting algorithm in earlier versions, which was sometimes useful. 0.9.5 and above have an improved algorithm which renders these flags irrelevant.

EXAMPLES

EXAMPLE-1:

To view compressed files content without decompressing the same :

$ bzcat test.txt.bz2

output:
(it will show the content of the file)
sff
adcbkjvd
sdvkhkjfv
dsvbkjsvdn
dsvbkjdsv


EXAMPLE-2:

To Decompress a  compressed file in stdout format:

$ bzcat -d file.txt.bz2

output:

(it will show the content of the file)
sff
adcbkjvd
sdvkhkjfv
dsvbkjsvdn
dsvbkjdsv

 


EXAMPLE-3:

To Display software version and License:

$ bzcat -L

output:

bzip2, a block-sorting file compressor. Version 1.0.6, 6-Sept-2010.
