To create folders in SAS, there are a variety of system options, functions, and commands that you can use. This article will demonstrate some of the options and functions you can use to create a folder using SAS. These functions can be automated to perform repetitive routine tasks and which avoid manual work and save a great deal of time.
DLCREATEDIR System option
DLCREATEDIR is a system option and when used with the libname statement can create folders.
options dlcreatedir;
libname newdir "/home/9to5sas/my_content/new";
Once you run the above statement, check the SAS log to see if the library assignment was successful or not.
SAS Log:
NOTE: Library NEWDIR was created.NOTE: Libref NEWDIR was successfully assigned as follows: Engine: V9 Physical Name: /home/9to5sas/my_content/new
To create subfolders, you can use multiple specifications in the LIBNAME statement.
options dlcreatedir;
libname newdir ("/home/9to5sas","/home/9to5sas/statistics");
The <span style="font-family: 'Courier Prime';">NODLCREATEDIR</span> specifies not to create a directory for a SAS library that is named in a LIBNAME statement.
DCREATE
DCREATE is a function that lets you create directories in your operating environment.
Syntax:
NewDirectory=DCREATE('Directory-name', 'parent-directory');
- Directory-name – It is the name of the directory to create. Do not include the path name here.
- Parent-directory – It is the complete pathname of the directory in which to create the new directory.
To create a new directory in the UNIX operating environment, with the directory name of ‘test’, follow this syntax:
NewDirectory=dcreate('test', '/home/test/abc/');
To create a new directory in the Windows operating environment, with the directory name of ‘test’, follow this syntax.
NewDirectory=dcreate('test', 'c:testdir');
X md (an X Statement)
With the help of X statements, you can give UNIX operating system commands directly from SAS.
md is a command in the Unix Operating system to make directories.
data _null_;
x 'md /home/9to5sas/test';
run;
Deleting a Directory
This example uses FDELETE to delete an empty directory to which you have write access. If the directory is not empty, the optional SYSMSG function returns an error message stating that SAS is unable to delete the file.
filename testdir 'physical-filename';
data _null_;rc=fdelete('testdir');
put rc=;
msg=sysmsg();
put msg=;
run;
