How to redirect stderr to a file as well
Hello everyone,

I'm a nooby in Linux, and I need some help.

I have a shell script like this:

Code:
echo "Start of script" > ../My_Log_Dir/Script_Name.log
 
..
 
cp ../My_DataIn/File.txt ../My_DataOut/ 2>> ../My_Log_Dir/Script_Name.log
 
rc=$?
 
..
 
echo "End of Script" >> ../My_Log_Dir/Script_Name.log
 
exit rc

And I execute the Shell like this:
Code:
../My_Shell_Dir/./My_Shell 2>../My_Log_Dir/Temp.log

Later I'll need to read Temp.log so I want it with all the error display's. But as I'm not getting the error display from de cp command. A tryed with the tee command and it worked, but I lost the return code from de cp command.

My idea here is to put the error display in a log file (used in other processes) and still keep it in the stderr. In this way I could use it when I invoque the shell script.

Hope someone can help!

Thank's!
