How to use Filename indata pipe to get the file names in a directory from Unix environment.

[karthic2612]

Hi,

Could someone help me to get the file names in a directory from Unix environment

Below code is for Windows, 

filename indata pipe 'dir "/home/euqyi/shared_folder/user_data/Vishal/pah/Inflated/Data Month March 2019/pah_dx_??????.txt" /b';

Will it work for Unix environment ? 

I am using the below piece of code 

filename indata pipe 'dir "/home/eupoq/shared_folder/user_data/Richard/pah/Inflated/Data Month March 2019/pah_dx_??????.txt" /b';

data file_list;
length fname $50;
infile indata truncover; /* infile statement for file names */
input fname $50.; /* read the file names from the directory */
call symput ('num_files',_n_); /* store the record number in a macro variable */
run;

And getting below error in Output data

fname

1 dir: cannot access /home/euqyi/shared_folder/user_

2 dir: cannot access /b: No such file or directory

Please help me on this.

Thanks,

Vishal

@karthic2612 I think for Unix the dir counterpart is ls. May be you can try.

What is the purpose of /b in Windows?

[karthic2612]

we can use the DOS command "dir" with the /B option to list only the file names.

Then just replacing dir with ls and not using /b is my suggestion. May be this will work.

Thanks...

It worked for me. By replacing ls with dir and /b option.

A simple

ls

is the UNIX equivalent of dir with the /b option.
