I am running a build script in which three executable files (100mb each) are uploaded to an FTP server.

The first upload can fail due to an FTP server space problem so our build process fails. This means I have to free some space from the server and run the build script again which is waste of time. I’d like to check the FTP size before uploading the exe to make sure space is there. If sufficient space is there then upload otherwise prompt user for input.

How can I check the FTP size in an ant script.

    As discussed in the comments, you can write a shell script (assuming the FTP server is a linux box) along the lines of:

    #!/bin/bash

FTPDIR="/path/to/ftp/dir"
echo `df -kl / | tail | awk '{print $4}'` > ${FTPDIR}/free_space.txt

    Make sure you replace path/to/ftp/dir with the actual path to the directory you will be downloading from.

    Add that script to the server’s crontab (crontab -e) and let it run every hour (0 * * * *) or so. You can download the free_space.txt file which contains the hourly updated free space of the FTP server.
