size
SIZE(1) General Commands Manual SIZE(1)
NAME
size - print the size of the sections in an object file
SYNOPSIS
size [ option ... ] [ object ... ]
DESCRIPTION
Size (without the -m option) prints the (decimal) number of bytes required by the __TEXT, __DATA and __OBJC segments. All other segments
are totaled and that size is listed in the `others' column. The final two columns is the sum in decimal and hexadecimal. If no file is
specified, a.out is used.
The options to size(1) are:
- Treat the remaining arguments as name of object files not options to size(1).
-m Print the sizes of the Mach-O segments and sections as well as the total sizes of the sections in each segment and the total size of
the segments in the file.
-l When used with the -m option, also print the addresses and offsets of the sections and segments.
-x When used with the -m option, print the values in hexadecimal (with leading 0x's) rather than decimal.
-arch arch_type
Specifies the architecture, arch_type, of the file for size(1) to operate on when the file is a fat file. (See arch(3) for the cur-
rently know arch_types.) The arch_type can be "all" to operate on all architectures in the file. The default is to display only
the host architecture, if the file contains it; otherwise, all architectures in the file are shown.
SEE ALSO
otool(1)
BUGS
The size of common symbols can't be reflected in any of the numbers for relocatable object files.
