truncate
TRUNCATE(1) BSD General Commands Manual TRUNCATE(1)NAME
truncate -- truncate or extend the length of files
SYNOPSIS
truncate [-c] -s [+|-]size[K|k|M|m|G|g|T|t] file ...
truncate [-c] -r rfile file ...
DESCRIPTION
The truncate utility adjusts the length of each regular file given on the command-line.
The following options are available:
-c Do not create files if they do not exist. The truncate utility does not treat this as an error. No error messages are displayed and
the exit value is not affected.
-r rfile
Truncate or extend files to the length of the file rfile.
-s [+|-]size[K|k|M|m|G|g|T|t]
If the size argument is preceded by a plus sign (+), files will be extended by this number of bytes. If the size argument is pre-
ceded by a dash (-), file lengths will be reduced by no more than this number of bytes, to a minimum length of zero bytes. Other-
wise, the size argument specifies an absolute length to which all files should be extended or reduced as appropriate.
The size argument may be suffixed with one of K, M, G or T (either upper or lower case) to indicate a multiple of Kilobytes,
Megabytes, Gigabytes or Terabytes respectively.
Exactly one of the -r and -s options must be specified.
If a file is made smaller, its extra data is lost. If a file is made larger, it will be extended as if by writing bytes with the value zero.
If the file does not exist, it is created unless the -c option is specified.
Note that, while truncating a file causes space on disk to be freed, extending a file does not cause space to be allocated. To extend a file
and actually allocate the space, it is necessary to explicitly write data to it, using (for example) the shell's '>>' redirection syntax, or
dd(1).
EXIT STATUS
The truncate utility exits 0 on success, and >0 if an error occurs. If the operation fails for an argument, truncate will issue a diagnostic
and continue processing the remaining arguments.
SEE ALSO dd(1), touch(1), truncate(2)STANDARDS
The truncate utility conforms to no known standards.
HISTORY
The truncate utility first appeared in FreeBSD 4.2.
