What Others Think

Hmm... Generally, it's not a good idea to parse the output of 'ls' (filenames might contain whitespace; 'date' has variable number of fields). I'd probably have used: stat -c %s * | awk '{total += $1} END {print total/(1024*1024*1024)}' Also, I don't understand why you've put in "head -n 65535". However, you've used an apostrophe correctly (in the title), so you can still have a +1 from me :-)

I'm a little unclear on what this does? Does it show the cumulative file size combined in bytes? & just because -> 1024*1024*1024 == 1024**3

why not just concatenate the files and pipe the output through wc? Like so : cat ./*.pl | wc To calculate the size of all your perl scripts Then again theres always du du /usr/bin/ How much disk space are all these user binaries taking up??

Any thoughts on this command? Does it work on your machine? Can you do the same thing with only 14 characters?
