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=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

       SIZE is an integer and optional unit (example: 10M is 10*1024*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.
