Nm lists the symbols defined or used by an object file, archive, or executable.
Usage:
go tool nm [options] file...
The default output prints one line per symbol, with three space-separated fields giving the address (in hexadecimal), type (a character), and name of the symbol. The types are:
T text (code) segment symbol t static text segment symbol R read-only data segment symbol r static read-only data segment symbol D data segment symbol d static data segment symbol B bss segment symbol b static bss segment symbol C constant address U referenced but undefined symbol
Following established convention, the address is omitted for undefined symbols (type U).
The options control the printed output:
-n
an alias for -sort address (numeric),
for compatibility with other nm commands
-size
print symbol size in decimal between address and type
-sort {address,name,none,size}
sort output in the given order (default name)
size orders from largest to smallest
-type
print symbol type after name
