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