Re^2: Reading DIR content and printing it

Thanks, And why would I not get output, when there is no "\" ?

open file, "< readfile.txt";

@filecontent = <file>;
for $f (@filecontent){
print "$f \n" ;
}
close file;

In addition to checking for errors, `$f` has a newline at its end. Again, if you had used warnings, Perl would have told you so: `Unsuccessful open on filename containing newline at -e line 1.` [download] Also, when printing out values, always put delimiters around them so you see whitespace: `print "[$f]\n";` [download]	[reply] [d/l] [select]
