Dear Maintainer,
*** Please consider answering these questions, where appropriate ***
* What led up to the situation?
I attempted to use awk to find the sum of file sizes in a directory.
* What exactly did you do (or not do) that was effective (or
ineffective)?
Precisely this. I have an externally attached USB storage disk
from SeaGate and on this disk are many resources. There are
large files such as Debian DVD iso install images thus :
# ls -lop Debian_resources
total 8410800
drwxr-xr-x 2 dclarke 4096 Nov 10 17:00 ./
drwxr-xr-x 19 dclarke 4096 Mar 29 2014 ../
-rw-r--r--. 1 dclarke 3938795520 Apr 26 2014 debian-7.5.0-amd64-DVD-1.iso
-rw-r--r--. 1 dclarke 679477248 Apr 26 2014 debian-7.5.0-amd64-lxde-CD-1.iso
-rw-r--r-- 1 dclarke 3994337280 Oct 18 10:52 debian-7.7.0-powerpc-DVD-1.iso
Therefore the sum of all filesizes in that directory would be about 8GB
however I wanted an exact number for my own reasons. The output from
awk was floating point by default thus :
# find ./Debian_resources -ls | \
> awk 'BEGIN{ ttl=0 }{ ttl+=$7 }END{ print ttl }'
8.61261e+09
Therefore I tried integer output from awk using printf :
# find ./Debian_resources -ls | \
> awk 'BEGIN{ ttl=0 }{ ttl+=$7 }END{ printf ( "%12i\n", ttl ) }'
2147483647
Seems obviously wrong and familiar looking :
# echo "2 31 ^ 1 - p q" | dc
2147483647
* What was the outcome of this action?
Integer output is limited to signed 32 bit however not overflow nor
underflow.
* What outcome did you expect instead?
I expected a precise sum of the filesizes from awk which is what I
see with Solaris 10 servers.
