I suspect the difference arises from the remote ftp code's rename command being implemented two different ways on the remote servers:

system 1
call the equivalent of C:
system ("mv oldfilename newfilename")

This would mean invoking the /bin/sh shell on the remote machine, which in turn would see a '#' character as a comment, which requires your escape "\" fix.

system 2
call the mv syscall or the C standard library's rename library call - this never invokes /bin/sh so no shell is called.

Note: /bin/sh can be a completely different object on different machines - it is NOT necessarily the shell that you use to run the ftp script locally.

ftp-upload - batch transfer local files to an FTP server SYNOPSIS
ftp-upload [any-switch]... {[repeatable-switch]... file...}... DESCRIPTION
ftp-upload is used to send local files to an FTP server. It isn't interactive, it's meant to be used from scripts. It is disciplined about its exit value and it doesn't output informational messages by default. There are two kinds of switches. Initial switches have to appear before any filenames, they affect the session as a whole. Repeatable switches can appear interspersed with the file names, they affect the transfer of the files which appear after them on the command line. OPTIONS
Initial switches These have to be used before any file names listed on the command line. --debug Turn debugging on. --help Show the usage message and die. --ignore-quit-failure Don't complain or set a failure exit code just because the QUIT command fails. This can be necessary because some servers, in blatant disregard of RFC 959, close the command channel when you send them an ABOR command. -v, --verbose Print informational messages to stdout. --version Show the version number and exit. Initial switches which specify connection information These also have to be used before any file names listed on the command line. They specify the information used to set up the FTP connec- tion. --account account This specifies the account to be used when logging into the remote system. This is distinct from the user name used to log in. Few systems need this. There is no default. -h, --host host Specify the host to which to connect. There is no default, you have to specify this switch. --passive Force the use of passive (PASV) transfers. Passive transfers are required with some firewall configurations, but if you have such you'd do better to configure Net::FTP so that it knows when to use them (see Net::Config). If you need to use passive transfers with certain (broken) servers, however, this switch is your best bet. Alternatively, you can set $FTP_PASSIVE to 1 in the environment (see Net::FTP). --password pw This gives the password which will be used to login. The default is your email address. Note that you should not specify a real (secret) password this way, as on most systems anybody on the machine can see the arguments you pass to your commands. Use one of other password-setting switches instead. -s, --password-stdin This tells ftp-upload to read the password from standard input. No prompt will be printed, and a single line will be read. Most peo- ple will use this switch to specify the password. Eg, echo 3x9sjJJh | ftp-upload -sh $host -u $user $file Using echo this way is safe where the --password switch isn't if the echo command is built in to the shell. --password-fd fd This is like --password-stdin except that it reads the password from the file descriptor numbered fd. ftp-upload -h $host -u $user --password-fd=3 3<$pw_file $file -u, --user user Specify the user name to use when logging in. The default is "anonymous". Repeatable switches These switches can be used anywhere on the command line (except after the last file name). They affect the transfer of files listed after them. --as remote-name Normally a file is transferred using the same name it has locally. If you use this switch the next file transferred will be called remote-name on the other host instead. ftp-upload --host $host --as index.htm index.html -a, --ascii Perform transfers in ASCII mode. -b, --binary Perform transfers in binary mode. This is the default. -d, --dir dir Change directory to dir on the FTP server before continuing. You can use this multiple times between files, ftp-upload will chdir once for each time you specify it. Using ".." as the dir will cause an FTP "CDUP" to be done rather than a "CWD". --full-path Normally uploaded files go into the current directory on the remote host, even when the local file name given contains slashes. Eg, if you say ftp-upload -h $host /etc/motd ftp-upload will upload the file as motd, not /etc/motd. This differs from how the standard ftp program works, and it also differs with how ftp-upload worked before version 1.3. If you specify --full-path, you'll get the other behavior. A request to upload dir/file will tell the server to store dir/file rather than file. When you use --as the --full-path setting doesn't matter. --full-path only tells the program what name to use when it's choosing the name. --no-full-path Disable --full-path. This is the default. -l, --ls Try to get a remote directory listing of files after transferring them. I say "try" because there's no guaranteed way to do this with the FTP protocol. The command I run is "LIST file". This will generally work if file doesn't contain any special characters. -L, --no-ls Disable the --ls behavior. --tmp-none Transfer files directly, don't do anything special to try to ensure that they don't appear under their real names on the remote machine until the transfer is finished. Each file is transferred with a single simple "STOR". This is the default. --tmp-samedir Transfer files to the remote machine using a temporary name, then rename them when the transfer finishes. This won't work if the remote server doesn't give a recognizable response to the "STOU" command. If the server's response to "STOU" isn't recognized by Net::FTP but is reasonable, Graham Barr might be willing to change Net::FTP to recognize it. If you like you can send the "--debug" output to me and I'll coordinate such requests. --tmp-dir dir Transfer files to dir on the remote host, then rename them when the transfer is complete. This is safer than --tmp-samedir because it doesn't use "STOU" and so it works with more servers. ftp-upload -h $host --tmp-dir incoming $file --tmp-format fmt Transfer files to "sprintf(fmt, file base name)", then rename them when the transfer is complete. Like --tmp-dir, this is safer than --tmp-samedir because it doesn't use "STOU" and so it works with more servers. ftp-upload -h $host --tmp-format tmp.%s $file AUTHOR
