how to use a call execute to pass a unix command

[alepage]

Hello,

I have a dataset name filelisting.  One of its variable is unixcommand and the first observation look like below

sed -i 's/"prod@test.net"//g' /.../sasmacro/email.sas

if I execute the above unix command directrly on the terminal via winscp, its works very well and it erase the sting "prod@test.net" from email.sas

How do we passed this unix command using 

data _null_; 

set filelisting;

call execute('something');

run;

CALL EXECUTE() is for submitting SAS code.

To run an operating system command (so if your SAS session is running on UNIX then it could be a UNXI command) you can use a PIPE.

To use an existing variable as the source of the filename (the string that will the command run in the pipe) use the FILEVAR= option of the INFILE statement.  To see if the command tries to send back any messages just read the lines it writes.

So if variable UNIXCOMMAND in the dataset FILELISTING has the commands to run then you want something like this:

data _null_; 
  set filelisting;
  infile unix pipe filevar=unixcommand end=eof;
  do while (not eof);
    input;
    put _infile_;
  end;
run;

Thank you very much

Left off the DO of the DO WHILE statement.  I will correct in the original post.
