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=FILE
              use this FILE's size

       -s, --size=SIZE
              use this SIZE

       --help display this help and exit

       --version
              output version information and exit

       SIZE may be (or may be  an  integer  optionally  followed  by)  one  of
       following: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G,
       T, P, E, Z, Y.

       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.

       Note that the -r and -s options are mutually exclusive.
