22 | o - BSD output has filenames at the end. | |
23 | o - BSD output can appear in different radicies. | |
24 | o - SysV output has less redundant whitespace. Filename comes at end. | |
25 | o - SysV output doesn't show VMA which is always the same as the PMA. | |
26 | o - We also handle core files. | |
27 | o - We also handle archives. | |
28 | If you write shell scripts which manipulate this info then you may be | |
29 | out of luck; there's no --compatibility or --pedantic option. | |
