Hi Don,

I am on Ubuntu Server 12.04 LTS. The files do not contain any special characters except _

Actually the format is something like

<xyz>_n1_n2_n3.pbx

where <xyz> is a prefix containing only alphabets [a-z A-Z]
n1 is a number less than 10
n2 is a number less than 1000
n3 is a number less than 10000
pbx is the extension

Safer and faster is
Code:
find . -type f |
while read i

Thanks.. Although I did not get an error for too many files with for I in *, find seems faster and as you mentioned safer if the number of files increase.
