Dynamic file name in variable

Shell Programming and Scripting
1

Hi guys.

i have a requirment as below.

I have a scripts which perform for loop

for i in /backup/logs -- it will give all the logs file
SC_RIO_RWVM_20120413064217303.LOG
SC_RIO_RWXM_20120413064225493.LOG
SC_RIO_RXXM_20120413064233273.LOG
...

do
open script.sh ---- in this file i have a variable which well be set as the above file name .

eg. when SC_RIO_RXXM_20120413064233273.LOG is getting process

then
in the called scripts the variable values should be set as
v_file name = SC_RIO_RXXM_20120413064233273.LOG.

when loop go into another file
SC_RIO_RXXM_20120413064233273.LOG

then
in the called scripts the variable values should be set as
v_file name = SC_RIO_RXXM_20120413064233273.LOG.

this means that the variable will accept the file name dynamically upon called scripts in the for loop.

Any help will save my work a lot, i am stuck with this logic.

Thanks

pass log file name to your script and assign that name to you script:

open script.sh $i

in your script assign variable as

v_file name=$1

Ok Fine,

Actually the file which will be called "scripts.sh" contains sql loader control file structure.
i don't know if i can add into it anything which additional to control file information.

Can you please reply if you know this

Hi can we modify the file contain while processing and close befor next lines get execute.

my control file has below text

load data
        BADFILE /backup/temp/rajesh/BadFiles/rio.bad
        append into TEMP_rio_RESP_TIME_LND
        (
        INSTALLATION_ID          CHAR
        TERMINATED BY "," ENCLOSED BY '"',
        TRANSACTION_ID           CHAR
        TERMINATED BY "," ENCLOSED BY '"',
         file_name)

----this file name should be set every time new file is getting processed.

so the code should be

for i in /backup/logs -- it will give all the logs file
SC_RIO_RWVM_20120413064217303.LOG
SC_RIO_RWXM_20120413064225493.LOG
SC_RIO_RXXM_20120413064233273.LOG

do

open ctl file and set the file name.
open scripts.sh --- which has referenced to ctl file just set above.

Thanks for understanding

so basically you need to alter your control file.

try this

sed -i s:file_name:${i}:g controlfile
open script.sh
