sasunixskeleton

Unless you are an experienced Unix script writer or you have gone through all the Unix tips and tutorials in the first section of this page then I would guess that at this stage of your Unix knowledge, you can see how useful it would be if you could run SAS inside a script and get it to talk to other Unix utilities but there is also no way you could write a script yourself. That is why I wrote sasunixskeleton. It writes a script for you and all you have to bother about is your SAS code and a few very simple things. First of all, here it is. You will need to paste it into your script library that you should have set up by now. Don't even bother to try to understand what is in it. When you get onto the Unix tips proper and go through all the examples I have there and do the practical exercises then I assure you that you will be able to understand it. But don't waste time now.

# Script     : sasunixskeleton
# Version    : 1.0
# Author     : Roland Rashleigh-Berry
# Date       : 30 July 2003
# Contact    : rolandberry@hotmail.com
# Purpose    : To create a skeleton script that runs SAS
# SubScripts : none
# Notes      : This utility generates a script to run SAS. It handles the Unix
#              side so you can concentrate on your SAS code. When the script is
#              generated you only need amend it where the word EDIT appears. You
#              should search for it. It will appear at the top where a usage
#              message it put out of the user does not suppl enough parameters
#              (if no parameters are allowed then you can delete this section).
# Usage      : sasunixskeleton
#              sasunixskeleton myscript

Put your code here. Use \$1 to resolve the first entered parameter.
Use \$2 to resolve the second entered parameter.

\$'s get treated like the &'s in front of macro variables by scripts.
It will try to resolve a Unix variable if you use one in a format.
To get round it you have to use a slash in front of the dollar like
this "\\$" .

Your final output should be written to _outfile. Do not change its
name. You can either reroute print output to it using a proc printto
like this:

proc printto print=_outfile;
run;

or you could use a data _null_ step like the following to put the
contents of a dataset out to the file like this:

data _null_;
  file _outfile notitle noprint;
  set xxxxx;
  put @1 xxxx;
run;
END


# Run the SAS code
sas -log "\$HOME" -sysin "\$HOME/${progname}.sas"


# Delete the temporary SAS code and optionally the log
rm -f \$HOME/${progname}.sas # \$HOME/${progname}.log 


# If output file exists then cat it and delete it
if [ -f $outfile ]
then
  cat $outfile
  rm -f $outfile
