nm
NM(1) General Commands Manual NM(1) NAME
nm - print name list SYNOPSIS
nm [-dgnopru] [file] ... OPTIONS
-d Print the offsets in decimal instead of in hex -g Print only external symbols -n Sort numerically rather than alphabetically -o Prepend file name to each line rather than only once -p Do not sort, print in symbol-table order -r Sort in reverse order -u Print only undefined symbols EXAMPLES
nm -n a.out # Print all symbols in numerical order nm -dg a.out # Print globals alphabetically in decimal DESCRIPTION
Nm prints the symbol table of executable files when it is available. If no file is given, the symbols in a.out are used. The format of the table is somewhat compatible with the one produced by asld when used with the -s option. The symbol table can be added with ast. Assembly language files do not have symbol tables.
