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 sparse 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).  Binary prefixes can be
       used, too: KiB=K, MiB=M, and so on.

       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.
