I am trying a simple code of reading dir content and printing it on cmd prompt. But its not working. What can be problem in here ?
opendir (dir, "C:\Users\Admin\Desktop\Staples files");
@dir_content = readdir(dir);
closedir(dir);
for $d(@dir_content){
print "$d ";
}
This code does not give any error nor does it print output
I have tried it in different ways as follows
opendir dir, "C:\Users\Admin\Desktop\Staples files\";
my @files = readdir(dir);
closedir(dir);
foreach $file(@files){
print "$file \n";
}
print $#files ;
I am getting following errors when I run this code
C:\Users\Admin>perl C:\Users\Admin\Desktop\perl_programs\printDir.pl
Scalar found where operator expected at C:\Users\Admin\Desktop\perl_programs\pri
ntDir.pl line 6, near "print "$file"
(Might be a runaway multi-line "" string starting on line 1)
(Do you need to predeclare print?)
Backslash found where operator expected at C:\Users\Admin\Desktop\perl_programs\
printDir.pl line 6, near "$file \"
(Missing operator before \?)
String found where operator expected at C:\Users\Admin\Desktop\perl_programs\pri
ntDir.pl line 6, at end of line
(Missing semicolon on previous line?)
syntax error at C:\Users\Admin\Desktop\perl_programs\printDir.pl line 6, near "p
rint "$file "
Can't find string terminator '"' anywhere before EOF at C:\Users\Admin\Desktop\p
erl_programs\printDir.pl line 6.
open file, "< C:\Users\Admin\Desktop\staples\readfile.txt";
@file_content = <file>;
for $f (@file_content){
print "$f \n";
}
This code does not give anu errors. but does not print content of files either.
