sum from ls -al |awk '{print $5}'
// AIX 5.3 & AIX 6.1

HTML Code:
ls -al |awk '{print $5}'
This gives each file's size in byte.
I need to get:

- the sum of all files in Giga bytes with loop.
- excluding the size of directories (ls -al returns the size of directories).

There are hundreds and thousands of files, so summing up with loop is needed.

Please advise.

Hi

give a try to
Code:
find . -maxdepth 1 -type f -exec stat -c "%s" {} \; | awk '{s+=$1} END {print s}'

You can remove the -maxdepth 1 if you want to add the subdir contents.

PHP Code:
root>find . -maxdepth 1 -type f -exec stat -c "%s" {} \; | awk '{s+=$1} END {print s}'
find: 0652-017 -maxdepth is not a valid option.

root>find .  -type f -exec stat -c "%s" {} \; | awk '{s+=$1} END {print s}' 
find: 0652-083 Cannot execute stat:: A file or directory in the path name does not exist.
find: 0652-083 Cannot execute stat:: A file or directory in the path name does not exist.

Nice one Smilie

So it's
Code:
find .  -type f -exec wc -c {} \; | awk '{s+=$1} END {print s}'

Code:
ls -al |awk '/^-/{s+=$5} END {print s}'

The conversion to Giga bytes is left as an exercise for the OP.

PHP Code:
root>ls -al |awk '/^-/{s+=$5} END {print s}' 
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.
