45 | The symbol table (name list) of each object in | |
46 | .Ar file(s) | |
47 | is displayed. | |
48 | If a library (archive) is given, | |
49 | .Nm | |
50 | displays a list for each | |
51 | object archive member. | |
52 | If | |
53 | .Ar file | |
54 | is not present, | |
55 | .Nm | |
56 | searches for the file | |
57 | .Pa a.out | |
58 | and if present, displays the symbol | |
59 | table for | |
60 | .Pa a.out . | |
61 | .Bl -tag -width flag | |
62 | .It Fl a | |
63 | Display symbol table entries inserted for use by debuggers. | |
64 | .It Fl g | |
