Total File Sizes by Extension
Every so often I have a brief love affair with awk. Today I got curious about the file sizes beneath a directory. In particular I wanted to see the totals by file extension. I did a quick search but came up with nothing. I decided that even if there is something out there to do the job, it'd be a lot more fun to do it myself. Tada:
ls -Rl | \
grep ^- | \
awk \
'{ split($9,e,"."); \
exts[e[length(e)==1?2:length(e)]]+=$5 } \
END \
{ for (ext in exts) printf "%10d %s\n", exts[ext], ext }' | \
sort
Yeah, there's an ugly hack in there to deal with file names that either have no extension or multiple dots in their name.
As an added bonus, looking at the previous post on awk got me all pissed off about "smart quotes" in WordPress blogs and the problems they cause when copying and pasting code examples. So, out they go.
