How to redirect a log file when using a shell script

alepage — Wed, 24 May 2023 16:04:48 GMT

Hello,

I am using the following shell script to trigger a sas program and I wish to redirect to log file. It does seems to work because I am getting two files.

/.../dapuipa.genjcl.log
/.../dapuipa.genjcl.2023-05-24.log (this one is empty)

I would like to have just one file, i.e. /.../dapuipa.genjcl.2023-05-24.log with information in it.

What's about this file: /.../dapuipa.genjcl.lst . Should I redirect and rename this file to avoid an error 11.

Please provide corrected script

orderdate=$1
ordertime=$2
surveyname=$3
env=$4

#-----------------------------------------------------------
# Cron entries do not execute login scripts.
# Let's run it in the context of our current process
#-----------------------------------------------------------

. /etc/profile

#---------------------------------------------------------------------------------
# Read the parameters and excute the SAS function dapuipa.genjcl.sas
#---------------------------------------------------------------------------------

echo "$orderdate|$ordertime|$name|$env"

sas  -sysparm  "$orderdate|$ordertime|$name|$env" /.../dapuipa.genjcl.sas >> "dapuipa.genjcl.$(date +'%Y-%m-%d').log"

#--------------------
# Exit procedure
#--------------------

exit $?

I suggest that you use the -LOG option on the sas command instead of the >> redirect in the shell script.

Use the -log option to specify the name of the LOG file. Use the -print option to specify the name of the print file (what SAS now calls the "listing" destination).

You might want to use the Unix output re-direction to a third error file to capture any error messages caused by disk outages or whatever.

So perhaps something like this:

cd /.../logfolder/ 

echo "$orderdate|$ordertime|$name|$env" >> dapuipa.genjcl.$(date +'%Y-%m-%d').cronlog

sas  -sysparm  "$orderdate|$ordertime|$name|$env" \
     -log dapuipa.genjcl.$(date +'%Y-%m-%d').log \
     -print dapuipa.genjcl.$(date +'%Y-%m-%d').log \
     /.../dapuipa.genjcl.sas \
     2>&1 >> dapuipa.genjcl.$(date +'%Y-%m-%d').cronlog

You should also look at the -set option as it will give you much more flexibility to pass in multiple parameters than the single string the old -sysparm option supports.

sas -set orderdate "$orderdate" -set ordertime "$ordertime" -set name "$name" -set env "$env" ....

Then in the SAS code you can use SYMGET() or %SYMGET() to retrieve the individual environment variable values instead of trying to parse it out of SYSPARM.

%let orderdate=%symget(orderdate);
%let ordertime=%symget(ordertime);
%let name=%symget(name);
%let env=%symget(env);

does the print option should end with .lst

ex:

-print dapuipa.genjcl.$(date +'%Y-%m-%d').lst \
