اخي الكريم هذا مضغوط ببرنامج bzip2
امر الضغط هو :
bzip2 -cdfkqstvzVL123456789 filename
هذه الحروف cdfkqstvzVL123456789 هي عباره عن الصلااحيات التي تريدها وهذه قائمه بالاوامر والصلاحياتي التي يمكنك استخدامها :
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 invocation 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. Normally, bzip2 will not overwrite existing output files. Also forces bzip2 to break hard links to files, which it otherwise wouldn't do.
bzip2 normally declines to decompress files which don't have the correct magic header bytes. If forced (-f), however, it will pass such files through unmodified. This is how GNU gzip behaves.
-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.
During compression, -s selects a block size of 200k, which limits memory use to around the same figure, at the expense of your compression ratio. In short, if your machine is low on memory (8 megabytes or less), use -s for everything. See MEMORY MANAGEMENT below.
-q --quiet
Suppress non-essential warning messages. Messages pertaining to I/O errors and other critical events will not be suppressed.
-v --verbose
Verbose mode -- 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
هذا بالنسبه للضغط , اما بالنسبه للفك فاستخدم هذه الطريقه :
bunzip2 -fkvsVL filenames
والاحرف هي نفس الاختيارات التي بالاعلى
فمثلا عند قيامك بفك ضغط برنامج بهذه الصيغ سوف يتحول الى
filename.bz2 becomes filename
filename.bz becomes filename
filename.tbz2 becomes filename.tar
filename.tbz becomes filename.tar
anyothername becomes anyothername.out
اتمنى الفكره تكون وضحت ,
تحياتي ,
