.sh DESCRIPTION
.it Nm
prints the symbol table from the output file of an
assembler or loader run.
Each symbol name is preceded by its value (blanks if undefined)
and one of the letters \fBU\fR (undefined) \fBA\fR (absolute) \fBT\fR
(text segment symbol),
\fBD\fR (data segment symbol), \fBB\fR
(bss segment symbol),
or \fBC\fR (common symbol).
If the symbol is local (non-external)
the type letter is in lower case.
The output is sorted alphabetically.
.s3
If no file is given, the symbols in
.it a.out
are listed.
If more than one file is given, each file name is printed preceding
the name list.
The ability to
.it nm
multiple files is most useful with the options
.bd \-c
or
.bd \-u.
