Hi, I am trying sas code with unix commands to read all directories /sub directories(in unix - IPswitch) but few folders don't have permission to read so I am getting cannot access in the log those report folders need to be captured in a dataset along with folder level owner/group information. Could you please help with that to crack?  Code used:    Data all_files; length  folder $600. file_name $256  owner $50 size 8 mod_date $12 mod_time $5  main_path$600. permissions $10 links 8  group $50 ; main_path=compress(cats(folder||'/'||file_name)); if file_name ^=' '; run; %macro read_folders(base_dir);   filename dirlist pipe "find &base_dir -type d";     data directories; infile dirlist truncover; input  folder_path $600.; if folder_path ne ''; run;   %if %sysfunc(exist(directories)) %then %do; data _null_; set directories nobs=num_dirs; call symput('num_dirs', num_dirs); run;   %if &num_dirs >0 %then %do;       data _null_; set directories ; call symputx('current_folder'||left(_n_), strip(folder_path)); run;  %do i=1 %to &num_dirs;   filename filelist pipe "ls -lt --time-style=long-iso &&current_folder&i";   Data files_&i ; infile filelist truncover; length line $1024; input line $1024.; if substr(line,1,1)  in ('t','') then delete; length permissions $10 links 8 owner $50 group $50 size 8 mod_date $12 mod_time $5 file_name $256 folder $600 datemodified 8; permissions =scan(line,1,' '); links=input(scan(line,2,' '),8.); owner=scan(line,3,' '); group=scan(line,4,' '); size=input(scan(line,5,' '),8.); mod_date=scan(line,6,' '); mod_time=scan(line,7, ' '); /*file_name=scan(line, -1, ' ');*/ length prefix $1024; prefix=catx(' ',permissions,links,owner,group,size,scan(line,6, ' '),scan(line,7, ' ')); start_pos=lengthn(prefix) +2; file_name=strip(substr(line,start_pos)); file_name=prxchange('s/^\d+\s*//', -1,file_name); datemodified=input(catx(' ',mod_date,mod_time),anydtdtm20.); format datemodified dateteime19.; folder="&&current_folder&i"; main_path=cats(folder,'/',file_name); if file_name^= ' '; run;   proc append base=all_files data=files_&i force; run;   %end;   Proc print data=all_files; title "All Files with details"; run; %end; %else %do;   %put ERROR: No directories found in &base_dir.; %end;   %end; %else %do; %put ERROR: Unable to create directories dataset.
