Executing commands with xargs
I have a SQL script that requires values from the environment in order to execute. I found a way to get the desired results but my process is a little choppy. Any suggestions on how to clean this up would be greatly appreciated.
SQL Script
-------------
select a, b, c
from d
where a = '$VAR'
/
quit
The following command builds a temporary file that will be executed to create the new SQL script for execution
----------------------------------------------------------------------------
more bmo.sql|xargs -i echo "echo \"{}\"" >> bmo.tmp.ux
Permissions are then changed
--------------------------------------
chmod 700 bmo.tmp.ux
File is then executed directing output to new file.
--------------------------------------------------------------
bmo.tmp.ux > bmo.tmp.sql
The new file can then be used and the *.tmp.* file can be removed after a successful execution.
------------------------------------------------------------------------
rm bmo.tmp.ux bmo.tmp.sql
I was hoping someone knew a trick so I could create my *.tmp.sql file using the xargs command. I have attempted to do so but xargs does not seem to replace the environment variable with it's contents when called from the echo.
Any suggestions would be apprecitated. Thanks.
