Glad you figured it out.
To overwrite the file, just use the '>' redirection instead of '>>':
Code:
$GAWK $IN_all > $OUT_all

Hey Mirni,

I tried that but it still adds to the original file. Any other ideas?

Thanks

mmm.... no. Please check that you are looking at the correct file.
You can try
Code:
echo 'Boom!' > $OUT_all

to see that your whole file $OUT_all contains nothing but one line with "Boom!" in it.
Tha is the definition of '>' operator: it truncates the file to zero length and then appends the output of previous command.

haha thanks for the boom! tip, it worked a treat.

Also I figured out where I was going wrong, my original code was

Code:
find /u/Picarro/DataLog/2011/june -type f -name "*dat" -exec cat {} >> june.dat \;

so I just removed one '>' and it worked. My fault, sorry!

Thanks for the help though, you've been great!

Glad you worked it out. BTW, find(1) is one very useful tool, that many of us use every day. Apart from the powerful -exec switch, that can be used to execute any command on the files, you can process the files one-by-one with the following construct:
Code:
find /path -type f -name "*.dat" | while read file ; do
   echo "Processing file $file "
   #do something with $file
done
