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=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.
