I concede my calculation was crude.
Interestingly, modifying my calculation to look
for tabs at the beginning of the line gives a
similar result:
# calculates the extra space required to
# use the given number of spaces/tab.
size()
{
count=`grep -RIo "^\`printf \"\t\"\`" . | wc -l`;
perl -e "print $count*$(($1-1))/1024/1024 . \" MiB\n\"";
}
size 8; => 49.7416791915894 MiB
and for git:
size 8; => 1.25082969665527 MiB
Anyway, thanks for the neat script.
