UNIX for Dummies Questions & Answers

Hello All,

I am working on an issue, where I need to check the max file size of a file. If the file size exceeds 2 GB, then I need to generate an error message. Since the file system does not allow a file to be created larger than 2 GB, I am planning to use named pipes & AWK file to acheive my purpose.

It would be great if someone helps me on this.

Thanks in advance,
Puru

Do you believe a FileSystem that has the 2GB files size limit will let you create a file greater?

Hi,

Yes, the unix box will not allow me to create a file that exceeds 2 Gig in size. ? But what I want to do is:
1) Keep a track on file size (by some logic that I am trying to think off
2) Catch the error that I will get when the file size exceeds the max size
3) Need to notify the users.

Thanks.

What for do you want to keep track of the file size? Your main goal seems to be to notify the user when an error occurs. So steps 2 and 3 should be sufficient.

@ CERO:

Yes, you are right. 2nd & 3rd step is needed. Could you please provide some guidence of doing that?

How is that file created/grown?
Do you have control of that process? If so you most likely can react on the return code.
Another way would be to check your systems logs for errormessages (that would be the only way that comes to my mind if you do not control the process) and some systems allow mail notification for errors.

Hello All,

I could find some solution, where I can redirect the data that I am creating into a pipe. As pipe can hold more than 2 GB, we can use the split -b option to check, if the no. of file created are more than 1. By doing this I was able to resolve the issue.

Thanks for the help
