Re: move remote files with different extension to a folder and create it if not exist.
I've understand theoption batch continueif the directory already exist, and the mkdir, but I don't understand the last two commandsoption batch abortandstat foldername.
With
option batch continue the mkdir would succeed, even if it failed to create a (non-existent) directory. stat foldername (in abort mode) fails, if the folder/file does not exist. So it's a way to abort the script, if it failed to create the folder.
