Windows批处理脚本中的通配符*

Question

I would like to use the * wildcard to list all the sas program files in my Windows directory. Thus I issue the command dir *.sas But when I do this the command will also list all sas datasets as well as catalogs because they have extensions .sas7bdat and .sas7bcat respectively. How do I restrict the dir command to only list the sas program files? Thanks.

There is a similar quesiton here. https://superuser.com/questions/825615/windows-wildcards-with-files-having-more-than-3-characters-extensions

The answer from that thread is that you cannot change the behavior. There were two proposed solutions:

• Switch to using powershell instead of cmd.exe
• add a step to filter the results of the dir command.

If you are doing it in SAS then you might use a program like this:

data want ;
   infile 'dir /b *.sas' pipe truncover ;
   input filename $200. ;
   if lowcase(scan(filename,-1,'.'))='sas' ;
run;
