Bash on RHEL 6.2

We have multiple shell scripts executed by cron jobs. Each Shell script has its own log files currently. Most of them have logs generated using spool command from Oracle RDBMS's sqlplus commmand.

Sample:

Code:

    #!/bin/bash

    sqlplus -s scott/tiger << EOF

    spool /home/oracle/scripts/logs/script1.log

    Some SQL goes here;

    spool off

    quit
    EOF

Now, our log monitoring team wants to have just one log file where all the shell scripts will scripts write to. We'll call it the 'CentralLogFile.log' for this discussion.

They say it is easy for their log mining tools to search for keywords in one log file rather than multiple log files. They will rotate this CentrallogFile file on a monthly basis.

But, I do not want to stop the current way of shell scripts generating separate log files for each execution. I want the shell scripts to write to both the CentralLogFile and the dedicated log file.

I found a simple & Elegant solution by Corona in the following link

Enable logging from within the shell script

Code:

exec >logfile
exec 2>&1

So, is it OK if use the following commands in red lines in all of my scripts so that it will write to the central log as well ?
Do you see any drawbacks, issues with this approach ?

Code:

#!/bin/bash

exec >/home/oracle/logmaster/CentralLogFile.log 
exec 2>&1

sqlplus -s scott/tiger << EOF

spool /home/oracle/scripts/logs/script1.log

Some SQL goes here;

spool off

quit
EOF
