Shell scripts and perl

Sara has asked for the wisdom of the Perl Monks concerning the following question:

Hello monks , I know you can do the follwing using shell scripting :

if [ ! -d $BA/bs/eerel/esGH060 ]; then
        mkdir $BA/bs/eerel/esGH060
[download]

how would I do the same thing in perl?

Consider using -e instead, if a file of the same name exists the mkdir command will fail. -- Brother Frankus. ¤	[reply]

using perl's mkdir: `if (! -d "$BA/bs/eerel/esGH060") { mkdir("$BA/bs/eerel/esGH060"); }` [download] almost the same as shell scripting Thanks. Hotshot	[reply] [d/l]

As already mentioned, mkdir is what you want, but if one of those intermediate directories doesn't exist, and you'd like to create the whole path in one go, you can use File::Path.	[reply]
