How to send several files contained in a directory using expect? - expect

Question

Hello I am writing the following script to automatically send several files using the ftp protocol, I decided to use expect to achieve this, I tried, the following:
#!/usr/bin/expect
Defining variables:
set user myUser
set gate myGate
set password myPassword
Defining a token that changes every 3 minutes:
set token [lindex $argv 0]
Here is the second parameter that is the name of the file to send:
set file [lindex $argv 1]
set server myServer
set password2 myPassword2
spawn ftp ${gate}
expect "some lines of response:"
send "${user}\r"
expect "password:"
send "${password}${token}\r"
expect "ftp>"
send "user myServer\r"
expect "Password:"
send "myPassword2"
Changing me to the appropriate directory:
send "pwd\r"
send "cd myFolder\r"
expect "successfully changed."
here is where the problem appears:
send "put ${file}\r"
interact
I run it as follows:
expect.exe ftpScript myToken filesToSend/
Everything is ok until the part where it tries to send the directory with the files:
ftp> myFolder/
250 Directory successfully changed.
ftp> put filesToSend/
filesToSend/: not a plain file.
ftp>
My folder is located at the same level where is stored my script:
ls:
filesToSend ftpScript
If I do an ls to the directory called filesToSend it looks as follows:
$ ls
file1 file10 file11 file12 file2 file3 file4 file5 file6 file7 file8 file9
Thus I would like to appreciate any idea to achieve this and how to improve my code since recently I started to learn expect, thanks in advance for the help.
After an answer I copied the script into the same folder where are located the files to send and I tried:
send "mput ${file}\r"
but after to run it:
expect.exe ftpScript token file10 file11 file12
with that three files for testing, I only was able to send file10 succesfully, after a confirmation:
mput file10? y
200 PORT command successful [translated to PASV by DeleGate].
150 Ok to send data.
226 File receive OK.
I believe that is only sending one file since the way that I am using to get the parameters I only have this line to get the parameters:
set file [lindex $argv 1]
I am not very sure if I need to use here a list and this is the reason that causes that only one file sent, just is considering argv1 this script, Thanks for the support, I would like to receive suggestions to fix it.

Answer 1

I believe you could solve your problem by using the command mput with a wildcard instead of put.
Edit your expect script to change the put line by the following :
send "mput ${file}\r"
Then invoke with :
expect ftpScript myToken filesToSend/*

Answer 2

I solved the issue as follows:
If we perform:
cd filesToSend
and then we modify the script as follows:
spawn ftp -i ${gate}
-i flag turns off the interactive mode which prompts for confirmation for every files.
Then we use:
send "mput *\r"
Finally we are able to send all the files without error to the destiny, running just:
expect.exe /myPath/ftpScript myToken
we receive all the files in the correct destiny:
file1 file10 file11 file12 file2 file3 file4 file5 file6 file7 file8 file9
Thanks for all the useful comments, after to research I decided to post my answer since maybe someone find this script useful to make their life easier, talking about to send multiple files using ftp,
