how to find total size of all files whose names starting with a*

OS: SunOS

du -h a* is giving individual file sizes.

Thanks,
Raj

Code:

perl -le'
 $s += -s for glob shift;
 printf "%f MB\n", $s/1024/1024;
  ' 'a*'

How about simply reading the du man page?

Code:

du -h -c a*

Pipe it through tail or grep or something to extract only the last line if you don't want the rest.

(Edit: D'oh! Just noticed the note about using SunOS. Please ignore this if your version of du doesn't have that option.

)

So here's an awk solution instead:

Code:

du -hb a* | awk '{ total+=$1 } END{ print total/1024"k" }'

Yes, I know that now. ...Did you not read the edited part of my post?

Notice also that the OP posted this in "Linux Newbie" instead of "Other *NIX" like he should have.

No, I suppose the correction was added after my second post ...
