.TH TRUNCATE "1" "January 2024" "GNU coreutils 9.4" "User Commands"
.SH NAME
truncate \- shrink or extend the size of a file to the specified size
.SH SYNOPSIS
.B truncate
\fI\,OPTION\/\fR... \fI\,FILE\/\fR...
.SH DESCRIPTION
.\" Add any additional description here
.PP
Shrink or extend the size of each FILE to the specified size
.PP
A FILE argument that does not exist is created.
.PP
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.
.PP
Mandatory arguments to long options are mandatory for short options too.
.TP
\fB\-c\fR, \fB\-\-no\-create\fR
do not create any files
.TP
\fB\-o\fR, \fB\-\-io\-blocks\fR
treat SIZE as number of IO blocks instead of bytes
.TP
\fB\-r\fR, \fB\-\-reference\fR=\fI\,RFILE\/\fR
base size on RFILE
.TP
\fB\-s\fR, \fB\-\-size\fR=\fI\,SIZE\/\fR
set or adjust the file size by SIZE bytes
.TP
\fB\-\-help\fR
display this help and exit
.TP
\fB\-\-version\fR
output version information and exit
.PP
The SIZE argument is an integer and optional unit (example: 10K is 10*1024).
Units are K,M,G,T,P,E,Z,Y,R,Q (powers of 1024) or KB,MB,... (powers of 1000).
Binary prefixes can be used, too: KiB=K, MiB=M, and so on.
.PP
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.
