Find the path of a filename

[chithra]

Dear All,

I need to find the pathname of a filename in sas. The input should be only the filename.

Is it possible in SAS? or anybody knows how this can be done in UNIX?

Thanks,

Chithra

Try this.....

data WANT;
filename="c:\windows\text.txt";
path=substr(filename,1,find(filename,reverse(scan(reverse(filename),1,"\")))-1);
run;

Hope this helps.

Thanks.

But i have only the file name text.txt with me.

Don't know the path.

To find a file on a Unix server, type this at a Unix command line: find / -name text.txt

I wouldn't recommend doing this from SAS, assuming that you only want to do it once 

[chithra]

yes..exactly.

Thanks. I use this command with pipe and it works fine.

Oh now i understand.

Now try this.

options noxwait;
FILENAME pathloc 'e:\test.txt';

data MYPATH;
  x "dir e:\sample.txt /s /p > e:\test.txt";
infile pathloc;
input locator $100.;
if indexw(locator,'Directory of');
run;

#1 assign a fileref (just like a libname statement) 

#2 Use x command and specify a directory and the file that will be searched, file is saved (same as fileref).

#3. Read the saved file.

#4 Look and retian the keywords "Directory of"

Hope this helps.

I tried this also. This helps.

Here's a step by step approach

data test;
  value='C:\Windows\Test.txt';
  file=scan(value,-1,"\");
  endpos=find(value,strip(file));
path=substr(value,1,endpos-1);
run;

To find the path to a filename use: 

%let myFilePath=%sysfunc(pathname(myFileName));

or for a library, use:

%let myLibraryPath=%sysfunc(pathname(myLibName));
