problems with system()

Hello,

     I am in a bit of a pickle and would greatly appreciate any help. I have code which writes inputs to a txt file. These inputs are used as inputs to a c program. What I am trying to do is use the redirect command < to run the code from php. The command is:

./a.out<test.txt through php I use: system("./a.out<test.txt"); which does not work, (i.e the code is not executed) also, rather strangly when I add another redirect: system("./a.out<test.txt>junk"); it does write the first couple of lines of the code output to the file. Can anyone see anything wrong? Any help would be great, thanks again John _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx
