truncate

TRUNCATE(1)							   User Commands						       TRUNCATE(1)

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.
