That stat sytnax only works with GNU stat. AIX doesn't even have a stat utility. It does offer istat, but that doesn't support format strings.

AIX find doesn't support -maxdepth.

Your suggestion will not work without GNU coreutils, which isn't very popular beyond the Linux world. Even their name says so, GNU's Not Unix Smilie

Any wc solution is going to be horribly inefficient, especially if there are many files or large files. Having to read every single byte when the byte count can be pulled from a single stat() syscall? Yikes.

Also, with so many files in a directory, the * .* could exceed the system's exec()'s limits.

This one gives the output as;
PHP Code:
6.36022e+12 
PHP Code:
root>find .  -type f -exec wc -c {} \; | awk '{s+=$1} END {print s}' 
and this one just hangs, not returning output..

Please advise.
It's probably not hung; it's just taking a long time. Aside from having to run wc thousands of times, it has to read over 6 trillion bytes.

I would advise using vgersh99's solution. All you need to do is use printf instead of print to manipulate the output format of very large numbers.
