[ILUG-BOM]How do I redirect streams ?

Hi all, I need some help from you guys. What I want to do is redirect the streams. For eg. Suppose we give ls > /dev/null, it redirects the STDOUT to /dev/null, but the STDERR remains to be console. Suppose I have a program which prints numbers from 1 to 999999 on STDOUT and a random string on STDERR for each corresponding number in STDOUT. Now let that program be called myprog. I run it in the background on the shell prompt. # myprog & 1 sdfsf 2 sdsdf ..... 7563 ... Now, I want to redirect the STDOUT and STDERR of the running background process to some files , say r1.txt or r2.txt without stopping or affecting the process. Inshort, the streams should be redirected at runtime. Please help me out... any trick or utility program or anything that I can do for it is welcome. Thanx in advance.
