in reply to SFTP ls command
Gah! Missed the 'S'. None of this applies, as it was for Net::FTP.
I had the same problem a few (8?) years back. The problem I encountered was that the 'ls' format for FTP isn't standardized. Many FTP programs will use something very unix-like, but you'll sometimes find (IBM MVS, etc.) systems where the format is different enough that the standard parser wasn't up to the task of splitting out the filenames. I'm digging through my archives to see if I can find the code, and if I do, I'll update this node. But if I recall correctly, what I wound up doing was calling the "long form" version that just returned the text of the directory listing, and then wrote my own parser to split out the filenames.
When your only tool is a hammer, all problems look like your thumb.
