If no object files are given as arguments, nnmm assumes `aa..oouutt'. OOPPTTIIOONNSS The long and short forms of options, shown here as alter- natives, are equivalent. --AA --oo ----pprriinntt--ffiillee--nnaammee Precede each symbol by the name of the input file where it was found, rather than identifying the in- put file once only before all of its symbols. --aa ----ddeebbuugg--ssyymmss Display debugger-only symbols; normally these are not listed. --BB The same as ----ffoorrmmaatt==bbssdd (for compatibility with the MIPS nnmm). --CC ----ddeemmaannggllee Decode (_d_e_m_a_n_g_l_e) low-level symbol names into user- level names. Besides removing any initial under- score prepended by the system, this makes C++ func- tion names readable. cygnus support 5 November 1991 1 nm(1) GNU Development Tools nm(1) --DD ----ddyynnaammiicc Display the dynamic symbols rather than the normal symbols. This is only meaningful for dynamic ob- jects, such as certain types of shared libraries. --ff _f_o_r_m_a_t Use the output format _f_o_r_m_a_t, which can be ``bsd'', ``sysv'', or ``posix''. The default is `bsd''. Only the first character of _f_o_r_m_a_t is significant; it can be either upper or lower case. --gg ----eexxtteerrnn--oonnllyy Display only external symbols. --nn --vv ----nnuummeerriicc--ssoorrtt Sort symbols numerically by their addresses, not alphabetically by their names. --pp ----nnoo--ssoorrtt Don't bother to sort the symbols in any order; just print them in the order encountered. --PP ----ppoorrttaabbiilliittyy Use the POSIX.2 standard output format instead of the default format. Equivalent to ``-f posix''. --ss ----pprriinntt--aarrmmaapp When listing symbols from archive members, include the index: a mapping (stored in the archive by aarr or rraannlliibb) of what modules contain definitions for what names. --rr cygnus support 5 November 1991 2 nm(1) GNU Development Tools nm(1) ----rreevveerrssee--ssoorrtt Reverse the sense of the sort (whether numeric or alphabetic); let the last come first. --tt _r_a_d_i_x ----rraaddiixx==_r_a_d_i_x Use _r_a_d_i_x as the radix for printing the symbol val- ues. It must be ``d'' for decimal, ``o'' for oc- tal, or ``x'' for hexadecimal. ----ttaarrggeett==_b_f_d_n_a_m_e Specify an object code format other than your sys- tem's default format. See oobbjjdduummpp(11), for informa- tion on listing available formats. --uu ----uunnddeeffiinneedd--oonnllyy Display only undefined symbols (those external to each object file). --VV ----vveerrssiioonn Show the version number of nnmm and exit. ----hheellpp Show a summary of the options to nnmm and exit.
