lists the symbols from object files objfile
. If no object files are given as arguments, nm
The long and short forms of options, shown here as alternatives, areequivalent.
- Precede each symbol by the name of the input file where it was found,rather than identifying the input file once only before all of itssymbols.
- Display debugger-only symbols; normally these are not listed.
- The same as--format=bsd(for compatibility with the MIPS nm).
- Decode (demangle) low-level symbol names into user-level names.Besides removing any initial underscore prepended by the system, thismakes C++ function names readable.
- Display the dynamic symbols rather than the normal symbols. This isonly meaningful for dynamic objects, such as certain types of sharedlibraries.
- -f format
- Use the output format format, which can be ``bsd'',``sysv'', or ``posix''. The default is ``bsd''.Only the first character of format is significant; it can beeither upper or lower case.
- Display only external symbols.
- Sort symbols numerically by their addresses, not alphabetically by theirnames.
- Don't bother to sort the symbols in any order; just print them in theorder encountered.
- Use the POSIX.2 standard output format instead of the default format.Equivalent to ``-f posix''.
- When listing symbols from archive members, include the index: a mapping(stored in the archive by ar or ranlib) of what modulescontain definitions for what names.
- Reverse the sense of the sort (whether numeric or alphabetic); let thelast come first.
- Sort symbols by size. The size is computed as the difference betweenthe value of the symbol and the value of the symbol with the next highervalue. The size of the symbol is printed, rather than the value.
- -t radix
- Use radix as the radix for printing the symbol values. It must be``d'' for decimal, ``o'' for octal, or ``x'' for hexadecimal.
- Specify an object code format other than your system's default format.See objdump(1),for information on listing available formats.
- Display only undefined symbols (those external to each object file).
- For each symbol, use debugging information to try to find a filename andline number. For a defined symbol, look for the line number of theaddress of the symbol. For an undefined symbol, look for the linenumber of a relocation entry which refers to the symbol. If line numberinformation can be found, print it after the other symbol information.
- Show the version number ofnmand exit.
- Show a summary of the options tonmand exit.
