Basic shell script not working

[chuckee]

Hi!
I am having a problem getting a shell script to always successfully run. The script simply concatenates text files together that have similar prefixes, and outputs them to another file.
It works in many instances, but it seems to break if there are 7 or more instances of files with one of the prefixes in the directory it runs in. In the example below, if there were 7 or more files that started with 'INTFR', for example, the script may not work. The problem may also lie with the size of the files - I am not sure.
Here is what it looks like:

cat /WORK/AREA/INTCCENT* > /WORK/AREA/INTCCENT1
cat /WORK/AREA/INTDLY* > /WORK/AREA/INTDLY1
cat /WORK/AREA/INTFR* > /WORK/AREA/INTFR1
cat /WORK/AREA/INTJF* > /WORK/AREA/INTJF1
cat /WORK/AREA/INTSAL* > /WORK/AREA/INTSAL
rm /WORK/AREA/*.0*.S

Does 'cat' not work under certain conditions? Is there some way to figure out why it is failing?

Thanks!
Charlie

there's no reason I can see. maybe thry cating to a different directory. Maybe what's happening is the file is then created, and it's trying to cat the new file to itself?

I'm not sure, but maybe if you try:

cat /WORK/AREA/INTCCENT* > /WORK/AREA/_INTCCENT1

to avoid the concatenation of result file ...

I am having this same issue. Did you get it figured out?
