Dynamically redirect output to duplicate files ???

Hi

There are many posts in this forum regarding reditecting output, but mine is a different problem, please have a look.

My shell script is redirecting output to a log file dynamically. That is it is using -
exec > log1.txt 2>&1
Hence all the traces are appearing in the log1.txt.

I want to redirect the same output to another file log2.txt which will contain the same thing that log1.txt is holding. I have tried in many different ways but nothing is working. "tee" isn't working here like -
exec > log1.txt 2>&1 | tee -a log2.txt

Can you please help me regarding this, I am totally clueless.

Thanks
Nirmalya Sinha

NAME
x2sys_merge - Merge an updated COEs tables SYNOPSIS
x2sys_merge -Amain_COElist.d -Mnew_COElist.d DESCRIPTION
x2sys_merge will read two crossovers data base and output the contents of the main one updated with the COEs in the second one. The second file should only contain updated COEs relatively to the first one. That is, it MUST NOT contain any new two tracks intersections (This point is NOT checked in the code). This program is useful when, for any good reason like file editing NAV correction or whatever, one had to recompute only the COEs between the edited files and the rest of the database. -A Specify the file main_COElist.d with the main crossover error data base. -M Specify the file new_COElist.d with the newly computed crossover error data base. OPTIONS
No space between the option flag and the associated arguments. EXAMPLES To update the main COE_data.txt with the new COEs estimations saved in the smaller COE_fresh.txt, try x2sys_merge -ACOE_data.txt -MCOE_fresh.txt > COE_updated.txt SEE ALSO
x2sys_binlist(1), x2sys_cross(1), x2sys_datalist(1), x2sys_get(1), x2sys_init(1), x2sys_list(1), x2sys_put(1), x2sys_report(1) GMT 4.5.7 15 Jul 2011 X2SYS_MERGE(1gmt)
