Subject: [9fans] awk: hex numbers? (and leak(1))
Date: Wed, 20 Sep 2006 12:33:59 +0200 [thread overview]
Message-ID: <200609201034.k8KAY0w20632@zamenhof.cs.utwente.nl> (raw)
is there a way to use awk to sum hex values?
i.e. I want to sum values in the 3rd column of
block 0x000af9a8 0x00000040 0x0001ddf3 0x00000000
block 0x000afd88 0x00000040 0x0001ddf3 0x00000000
I have tried to make awk use an external program
to do the hex-to-dec conversion, but that was very
slow (probably due to many page faults).
(in the end I resorted to perl...)
context:
I've been fiddling with leak(1) to make it print
an overview of how much memory is allocated where,
as in:
location total calls
amount
allocated
src(0x0001d8f1); // 247648 20
src(0x000067f8); // 24256 59
src(0x0001da70); // 15760 6
src(0x000128ac); // 8256 1
src(0x000210f8); // 4128 66
src(0x00014bc2); // 3648 57
[...]
src(0x00006586); // 64 1
src(0x00011a50); // 64 1
src(0x000067c7); // 64 1
src(0x0001ca32); // 32 1
// 326544
I found it quite useful to get insight in where
the memory goes (even when it is not leaked) -
but maybe we already have this functionality
somewhere, and I missed it?
Axel.
