size(1) output is not padded and uses a single tab between each column
which often looks ugly:
$ size bsd /usr/lib/libc.so.96.4 `which echo cc`
text data bss dec hex
896234 31208 54664 982106 efc5a /usr/lib/libc.so.96.4
106152 11200 12640 129992 1fbc8 /bin/echo
84398221 41416 343049 84782686 50dae5e /usr/bin/cc
The GNU implementation looks less off:
# pkg_add binutils
binutils-2.39: ok
$ gsize bsd /usr/lib/libc.so.96.4 `which echo cc`
text data bss dec hex filename
896234 31208 54664 982106 efc5a /usr/lib/libc.so.96.4
106152 11200 12640 129992 1fbc8 /bin/echo
84398221 41416 343049 84782686 50dae5e /usr/bin/cc
I haven't checked their code, but padding fields to seven chars and
delimiting with a tab yields their format (modulo "filename" printing):
$ obj/size bsd /usr/lib/libc.so.96.4 `which echo cc`
text data bss dec hex
896234 31208 54664 982106 efc5a /usr/lib/libc.so.96.4
106152 11200 12640 129992 1fbc8 /bin/echo
84398221 41416 343049 84782686 50dae5e /usr/bin/cc
Big files are still off, but at least fields are now aligned.
Another alternative could be to pad fields to eight chars and delimit
with a space, causing both small and big files to align nicely whilst
staying under 80 chars total width with reasonable file names
(which I left delimited with a tab... coulde be space for consistency):
$ grep %8 nm.c
printf("%8s %8s %8s %8s %8s\n",
printf("%8lu %8lu %8lu %8lu %8lx",
$ obj/size bsd /usr/lib/libc.so.96.4 `which echo cc`
text data bss dec hex
896234 31208 54664 982106 efc5a /usr/lib/libc.so.96.4
106152 11200 12640 129992 1fbc8 /bin/echo
84398221 41416 343049 84782686 50dae5e /usr/bin/cc
What do others think?
Diff below switches to the GNU format, keeping tabs in outputs.
One possible concern is scripts parsing size(1) output with anything but
awk(1), but at least base does not seem to contain Makefiles that depend
on the exact current format.
