NAME
       truncate - shrink or extend the size of a file to the specified size
SYNOPSIS
       truncate OPTION... FILE...
DESCRIPTION
       Shrink or extend the size of each FILE to the specified size
       A FILE argument that does not exist is created.
       If  a  FILE  is larger than the specified size, the extra data is lost.
       If a FILE is shorter, it is extended and the extended part (hole) reads
       as zero bytes.
       Mandatory  arguments  to  long  options are mandatory for short options
       too.
       -c, --no-create
              do not create any files
       -o, --io-blocks
              treat SIZE as number of IO blocks instead of bytes
       -r, --reference=RFILE
              base size on RFILE
       -s, --size=SIZE
              set or adjust the file size by SIZE bytes
       --help display this help and exit
       --version
              output version information and exit
       The SIZE argument is an integer and  optional  unit  (example:  10K  is
       10*1024).   Units  are  K,M,G,T,P,E,Z,Y  (powers  of 1024) or KB,MB,...
       (powers of 1000).
       SIZE may also be prefixed by one of the following modifying characters:
       '+' extend by, '-' reduce by, '<' at most, '>' at least, '/' round down
       to multiple of, '%' round up to multiple of.
