NAME

truncate – shrink or extend the size of a file to the specified size
 

SYNOPSIS

truncate

OPTIONFILE
 

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.
