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 universal file. (See arch(3) for the currently 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

NAME
strings - find the printable strings in a object, or other binary, file SYNOPSIS
strings [ - ] [ -a ] [ -o ] [ -t format ] [ -number ] [ -n number ] [--] [file ...] DESCRIPTION
Strings looks for ASCII strings in a binary file or standard input. Strings is useful for identifying random object files and many other things. A string is any sequence of 4 (the default) or more printing characters ending with a newline or a null. Unless the - flag is given, strings looks in all sections of the object files except the (__TEXT,__text) section. If no files are specified standard input is read. The file arguments may be of the form libx.a(foo.o), to request information about only that object file and not the entire library. (Typ- ically this argument must be quoted, ``libx.a(foo.o)'', to get it past the shell.) The options to strings(1) are: -a This option causes strings to look for strings in all sections of the object file (including the (__TEXT,__text) section. - This option causes strings to look for strings in all bytes of the files (the default for non-object files). -- This option causes strings to treat all the following arguments as files. -o Preceded each string by its offset in the file (in decimal). -t format Write each string preceded by its byte offset from the start of the file. The format shall be dependent on the single character used as the format option-argument: d The offset shall be written in decimal. o The offset shall be written in octal. x The offset shall be written in hexadecimal. -number The decimal number is used as the minimum string length rather than the default of 4. -n number Specify the minimum string length, where the number argument is a positive decimal integer. The default shall be 4. -arch arch_type Specifies the architecture, arch_type, of the file for strings(1) to operate on when the file is a universal file. (See arch(3) for the currently know arch_types.) The arch_type can be "all" to operate on all architectures in the file, which is the default. SEE ALSO
