How to download multiple files with Corecmd.exe

drifter · Post by **drifter** » Mon Feb 10, 2014 11:23 am

I am able to download files OK using corecmd.exe, but I often have to script the download of multiple files. Is there a way to do this in one call to corecmd.exe rather than calling corecmd.exe for each file I need to download.

Currently I script something like this,

corecmd.exe -site MY_SITE -s -d /remotefile1 -p C:\ftp_download_dir

corecmd.exe -site MY_SITE -s -d /remotefile2 -p C:\ftp_download_dir

corecmd.exe -site MY_SITE -s -d /remotefile3 -p C:\ftp_download_dir

Can I script the download of the multiple files in one call to corecmd.exe? Rather than constantly opening and closing the connection to the remote server?

Note: I do not want to download all files in a remote folder, only specific selected files.

Thanks in advance.

use the -scal <scriptfile> option. See help topic "command line" for more info.

<scriptfile> would be a file containing something like this:

For FTP/SSL/FTPS:

CWD /remote_path/
RETR remotefile1
RETR remotefile2
RETR remotefile3

or for SFTP:
RETR /remote_path/remotefile1
RETR /remote_path/remotefile2

If the script hangs, add the QUIT command to the last line.

Thanks for your suggestion regarding using a script.

The script is working. However I have noticed an unusual behaviour in that the script seems to be executed twice. This is not a big problem as such, since it just downloads the files twice. But is this a bug?

For reference, I am connecting to a remote site on port 990, over SSL/TLS, and with SSL Session Reuse ticked.

My command,
corecmd.exe -site MY_SITE -s -scal myscriptfile.txt -log mylog.log

My script file,
CWD /<remotefolder>/
RETR <file1>
RETR <file2>

The resulting log,

add the -s parameter to the beginning of the cmd line, it could be a bug in the LE version.

Thanks. I have moved the -s parameter to the beginning of the command line but this does not make a difference.

corecmd.exe -s -site MY_SITE -scal myscriptfile.txt -log mylog.log

I was using build 1792. I have upgraded to build 1795 and can confirm that this behaviour still exists.

Fixes will be in build 1796 and greater.
