NAME

       pmempool-dump - dump user data from persistent memory pool

SYNOPSIS

              $ pmempool dump [<options>] <file>

DESCRIPTION

       The  pmempool  invoked  with  dump  command dumps user data from specified pool file.  The
       output format may be either binary or hexadecimal.

       By default the output format is hexadecimal.

       By default data is dumped to standard output.  It is possible to dump data to  other  file
       by specifying -o option.  In this case data will be appended to this file.

       Using  -r  option  you  can  specify number of blocks/bytes/data chunks using special text
       format.  See RANGE section for details.

   Available options:
       -b, --binary

       Dump data in binary format.

       -r, --range <range>

       Range of pool file to dump.  This may be number of blocks for  blk  pool  type  or  either
       number of bytes or number of data chunks for log pool type.

       -c, --chunk <size>

       Size of chunk for log pool type.  See pmemlog_walk(3) in libpmemlog(7) for details.

       -o, --output <file>

       Name of output file.

       -h, --help

       Display help message and exit.

RANGE

       Using  -r,  –range  option it is possible to dump only a range of user data.  This section
       describes valid format of <range> string.

       You can specify multiple ranges separated by commas.

       <first>-<last>

       All blocks/bytes/data chunks from <first> to <last> will be dumped.

       -<last>

       All blocks/bytes/data chunks up to <last> will be dumped.

       <first>-

       All blocks/bytes/data chunks starting from <first> will be dumped.

       <number>

       Only <number> block/byte/data chunk will be dumped.

EXAMPLE

              $ pmempool dump pool.bin

       Dump user data from pool.bin file to standard output

              $ pmempool dump -o output.bin -r1,10-100 pool_blk.bin

       Dump block number 1 and blocks from 10 to 100 from pool_blk.bin containing pmem  blk  pool
       to output.bin file

              $ pmempool dump -r 1K-2K pool.bin

       Dump data form 1K to 2K from pool.bin file.
