size – display section sizes and total size of ELF objects

SYNOPSIS DESCRIPTION DISPLAY FORMATS Berkeley Style Output System V Style Output EXIT STATUS EXAMPLES SEE ALSO HISTORY AUTHORS

size [--format= format] [--help] [--radix= radix] [--totals] [--version] [-ABVdhotx] [file ...]

If 'berkeley' style output is in effect, an initial header line naming fields will be output, followed by one line of output for each ELF object specified on the command line or found in an archive.

Each line will contain the following whitespace separated fields in order:

1. The size of the text segment in the object.
2. The size of the data segment in the object.
3. The size of the 'bss' segment in the object.
4. The total size of the object in either decimal or octal. Decimal output is used if the specified output radix for numeric values is 10 or 16. Octal output is used if the radix being used for numeric values is 8.
5. The total size of the object in hexadecimal.
6. The file name of the object.

If option --totals was specified, an additional line in the same format as above will be output at the end containing the sum of the respective fields. The file name field for the line will contain the string '(TOTALS)'.

If System V style output is selected, size will output the following information for each object:

1. The name of the object followed by a colon.
2. A header line containing the names of fields of subsequent lines.
3. One line per section present in the object. Each line has three fields:
   1. The name of the section.
   2. Its size, in the selected radix for numeric values.
   3. The address associated with the section, in the selected numeric radix.
4. A line whose section name field contains the string 'Total' and whose size field contains the sum of all reported section sizes.

The utility exits 0 on success, and >0 if an error occurs.

To display the section sizes for /bin/ls use:

$ size /bin/ls
text       data       bss        dec        hex        filename
20975      540        392        21907      5593        /bin/ls

To display sizes and total for /bin/ls and /bin/dd in hexadecimal, use:

$ size -tx /bin/ls /bin/dd
text       data       bss        dec        hex        filename
0x51ef     0x21c      0x188      21907      5593        /bin/ls
0x3df5     0x170      0x200      16741      4165        /bin/dd
0x8fe4     0x38c      0x388      38648      96f8       (TOTALS)

To display section sizes for /bin/ls in System V format use:

$ size -A /bin/ls
/bin/ls  :
