Escape characters in batch scripts

Question

I have the following script to automate uploading a file to a remote server. The problem is that the password I have been given is full of special characters which are killi

Answer 1

In your case you could simply type your file to reveal the password, just before you delete the file.

But it's better to use the delayed expansion, because then the special characters lose their "special" behaviour, even carets and percent signs.

@echo off
setlocal EnableDelayedExpansion
set /p passwd=Enter pwd
echo user myloginname> ftpcmd.dat
echo mypassword>> ftpcmd.dat
echo bin>> ftpcmd.dat
echo put !passwd! >> ftpcmd.dat
echo quit>> ftpcmd.dat
type ftpcmd.dat
ftp -n -s:ftpcmd.dat myserver

The second problem is the ftp command, where the characters also need escaping. Perhaps (like Vicky wrote) the backslash could work. You can place it before each single character, by using a for-loop
