p If an explicit output file name is not specified using the .Fl o option, the .Nm utility will modify its input arguments in-place.

p The .Nm utility supports the following options: l -tag -width indent t Fl d | Fl g | Fl S | Fl -strip-debug Remove debugging symbols only. t Fl h | Fl -help Print a help message and exit. t Fl -only-keep-debug Remove all content except that which would be used for debugging. t Fl o Ar outputfile | Fl -output-file= Ns Ar outputfile Write the stripped object to file .Ar outputfile instead of modifying the input in-place. Only a single input object should be specified if this option is used. t Fl p | Fl -preserve-dates Preserve the object's access and modification times. t Fl s | Fl -strip-all Remove all symbols. t Fl -strip-unneeded Remove all symbols not needed for further relocation processing. t Fl w | Fl -wildcard Use shell-style patterns to name symbols. The following meta-characters are recognized in patterns: l -tag -width "...." -compact t Li ! If this is the first character of the pattern, invert the sense of the pattern match. t Li * Matches any string of characters in a symbol name. t Li ? Matches zero or one character in a symbol name. t Li [ Mark the start of a character class. t Li \e Remove the special meaning of the next character in the pattern. t Li ] Mark the end of a character class. .El t Fl x | Fl -discard-all Discard all non-global symbols. t Fl I Ar format | Fl -input-target= Ns Ar format These options are accepted, but are ignored. t Fl K Ar symbol | Fl -keep-symbol= Ns Ar symbol Keep the symbol .Ar symbol even if it would otherwise be stripped. This option may be specified multiple times. t Fl N Ar symbol | Fl -strip-symbol= Ns Ar symbol Remove the symbol .Ar symbol even if it would otherwise have been kept. This option may be specified multiple times. t Fl O Ar format | Fl -output-target= Ns Ar format Set the output file format to .Ar format . For the full list of supported formats, please see the documentation for function .Xr elftc_bfd_find_target 3 . t Fl R Ar sectionname | Fl -remove-section= Ns Ar sectionname Remove the section named by the argument .Ar sectionname . This option may be specified multiple times. t Fl V | Fl -version Print a version identifier and exit. t Fl X | Fl -discard-locals Remove compiler-generated local symbols. .El .Sh DIAGNOSTICS .Ex -std .Sh SEE ALSO .Xr ar 1 , .Xr elfcopy 1 , .Xr ld 1 , .Xr mcs 1 , .Xr elf 3 , .Xr elftc_bfd_find_target 3 , .Xr fnmatch 3
