I guess another option would be to implement something like a STATUS option for filename pipe. This is an example of the SAS System's ability to capitalize on operating environment capabilities. I am using the following SAS code to find all files and their sizes under the directory &directory.. filename tmp pipe "find &directory. Apparent invocation of macro not resolved in sas filename pipe. Other system functions that manipulate external files and directories require that the files be identified by fileref rather than by physical filename. Use the FILENAME ZIP with GZIP to get the tarball (.tar file). But how does one submit multiple commands in the same filename (or file) statement? To get around this, you need to let SAS know that there are no column headings provided in the input text file. FILENAME fileref PIPE 'operating-system-command' option-list; Here is additional information about the syntax above: fileref: Can be any valid fileref, as described in Referencing External Files. The name that is associated with the file or device is called a fileref (file reference name). When the fileref is used for writing, the output from the SAS System is read in by the specified UNIX command, which then executes. When you are disassociating a currently-assigned fileref or when you are listing file attributes with the FILENAME statement, specify a fileref that was previously assigned with a FILENAME statement or a host-level command.

The PIPE device-type keyword in the FILENAME statement allows SAS to execute a command outside of SAS and redirect its results to SAS. Then (and I haven't tried this) you might be able to use FILENAME ZIP (not GZIP) to get to the individual tarball members. FILENAME returns 0 if the operation was successful, 0 if it was not successful. The output from an operating system command can be read into SAS as if it were an ordinary external file. filename pipe “”; 其中command是DOS命令,pipe将command里面的信息导入虚拟文件fileref里面,再在data步里面调用。例如我们需要读取电脑里面一个文件夹(D:\TEMP)下面所有的txt文件: filename temp pipe "D:\TEMP\*.txt /b"; 可以进一步将文件名导入宏变量进行进一步操作 SAS | The Power to Know; Customer Support; SAS Documentation; SAS® 9.4 and SAS® Viya® 3.4 Programming Documentation SAS 9.4 / Viya 3.4.
