How to see if a directory exists or not in Perl?

Question

To see if a file exists before using it, we can use:

if (-e "filename.cgi") {  #proceed with your code }  

But how to indentify a directory exists or not?

Answer 1

Use -d (full list of file tests)

if (-d "cgi-bin") {     # directory called cgi-bin exists } elsif (-e "cgi-bin") {     # cgi-bin exists but is not a directory } else {     # nothing called cgi-bin exists } 

As a note, -e doesn't distinguish between files and directories. To check if something exists and is a plain file, use -f.
