git-ftp delete folder at target

I have working Jenkinsfile and want to add delete of my target before it copies and uses git-ftp and is on my OS /usr/local/bin and works with the 2nd command here. THIS FAILS sh ('#!/bin/sh -e\n' + 'git ftp rm --user ${FTP_USER} --passwd ${FTP_PASS} ftp://[login to view URL]*') THIS WORKS! sh ('#!/bin/sh -e\n' + 'git ftp push --user ${FTP_USER} --passwd ${FTP_PASS} ftp://[login to view URL]') Here is a link that has some information; rather than an delete/rm it does an init [login to view URL] Eitherway; it will be great if you bid a reasonable amount? Need this completed by 6pm EST NYC time.
