Summing file size and output

:rolleyes:Hi,

I need to find the sum of size of specific files in my directory

Say for ex,
mydir$ ls -ltr
permisssion links user group size date time filename

I want to display the sum of size of filenames having pattern "TS55". Note file size in this directory is near 400 MB.

mydir$ ls -ltr | grep "TS55" | awk '{sum+=$5} END {print sum}'
1.52757e+11

I want to have the output in full decimal form and not in exponential form like this. Please advice on this.
Thanks,
Ramkrix

Have you tried a formatted printf command?
