ulimit problem

i've encountered the following problem with sco unixware7.

after using the "ulimit -f unlimited" command and then using "ulimit -a" it lists the filesize as unlimited.

BUT, when type the ulimit command without parameters, the output is given as 4194303

so i can't create a file bigger than 2GB. the filesystem does support largefiles and i've enabled it as well.

ulimit is a shell built-in command. Maybe the shell you are using doesn't know about large files. So I would try another shell.

i'm logged in as root. do i still have to change the shell?

how do you change a shell?

If it's not working, you obviously need to try something. As for changing your shell, you need to figure out which shell you are using and what shells are available on your system. Then, let's say you are using "csh" and you found that you have ksh available. From your csh prompt, you can type:
ksh
and now you are running ksh. If you are unable to determine what shells are on your system, you will have to wait for a unixware expert to show up. I don't have a unixware system.

We are on a project in Tanzania, and the only resident Unix expert is on honeymoon, and will only return at the end of the month.

We have been thrown in at the deep end here, and are completely new to the Unix envionment, so the concept of command shells is new.

We have managed to establish that there are system limits that determine the maximum file size limits that can be set using ulimit. We need to invoke the commands that change these limits from the 32bit limits to the 64 bit limits that the operating system allows. We suspect that the solution lies in somewhere in setrlimit64 function, but we have no idea how to operate the function. If we could get an example, we would probably find our solution.

Thanks with the help to date
