The .Nm utility can operate on ELF objects, on .Xr ar 1 archives containing ELF objects, and on core dumps. If no file name is specified on the command-line, .Pa a.out is assumed. .Pp The .Nm utility recognized the following options: .Bl -tag -width indent .It Fl -format= Ns Ar format Display output using the format specified by argument .Ar format . Supported values for this argument are: .Sq berkeley and .Sq sysv . The default output format is .Sq berkeley . See .Sx Display Formats below for more information. .It Fl -help Display a help message and exit. .It Fl -radix= Ns Ar radix Display numeric values using the radix specified by argument .Ar radix . Supported values for .Ar radix are 8, 10 and 16. The default radix is 10. .It Fl -totals Shows cumulative totals of section sizes from all objects. This option is ignored for System V style output. .It Fl -version Display a version identifier and exit. .It Fl A Equivalent to specifying option .Fl -format= Ns Ar sysv . .It Fl B Equivalent to specifying option .Fl -format= Ns Ar berkeley . .It Fl V Equivalent to specifying option .Fl -version . .It Fl d Equivalent to specifying option .Fl -radix= Ns Ar 10 . .It Fl h Equivalent to specifying option .Fl -help . .It Fl o Equivalent to specifying option .Fl -radix= Ns Ar 8 . .It Fl t Equivalent to specifying option .Fl -totals . .It Fl x Equivalent to specifying option .Fl -radix= Ns Ar 16 . .El .Sh DISPLAY FORMATS .Ss Berkeley Style Output If .Sq 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. .Pp Each line will contain the following whitespace separated fields in order: .Bl -enum -compact .It The size of the text segment in the object. .It The size of the data segment in the object. .It The size of the .Sq bss segment in the object. .It 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. .It The total size of the object in hexadecimal. .It The file name of the object. .El .Pp If option .Fl -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 .Sq (TOTALS) . .Ss System V Style Output If System V style output is selected, .Nm will output the following information for each object: .Bl -enum -compact .It The name of the object followed by a colon. .It A header line containing the names of fields of subsequent lines. .It One line per section present in the object. Each line has three fields: .Bl -enum -compact .It The name of the section. .It Its size, in the selected radix for numeric values. .It The address associated with the section, in the selected numeric radix. .El .It A line whose section name field contains the string .Sq Total and whose size field contains the sum of all reported section sizes. .El .Sh EXIT STATUS .Ex -std .Sh EXAMPLES To display the section sizes for .Pa /bin/ls use: .Bd -literal $ size /bin/ls text data bss dec hex filename 20975 540 392 21907 5593 /bin/ls .Ed .Pp To display sizes and total for .Pa /bin/ls and .Pa /bin/dd in hexadecimal, use: .Bd -literal $ 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) .Ed .Pp To display section sizes for .Pa /bin/ls in System V format use: .Bd -literal $ size -A /bin/ls /bin/ls : section size addr \&.interp 21 4194704 \&.note.ABI-tag 24 4194728 \&.hash 624 4194752 \&.dynsym 2088 4195376 \&.dynstr 810 4197464 \&.rela.dyn 120 4198280 \&.rela.plt 1656 4198400 \&.init 19 4200056 \&.plt 1120 4200076 \&.text 15224 4201200 \&.fini 14 4216424 \&.rodata 1472 4216448 \&.data 80 5267456 \&.eh_frame 1624 5267536 \&.dynamic 384 5269160 \&.ctors 16 5269544 \&.dtors 16 5269560 \&.jcr 8 5269576 \&.got 576 5269584 \&.bss 528 5270176 \&.comment 686 0 Total 27110 .Ed .Sh SEE ALSO .Xr ar 1 , .Xr nm 1 , .Xr objdump 1 , .Xr readelf 1 , .Xr strings 1 , .Xr elf 3 , .Xr gelf 3 .Rs .%A "AT&T Unix Systems Labs" .%T "System V Application Binary Interface" .%O http://www.sco.com/developers/gabi/ .Re .Sh HISTORY The .Nm utility first appeared in .At v6 . .Sh AUTHORS .An -nosplit The .Nm utility was re-written by .An S.
