Crontab + Auto-fetch FTP file
Hey everyone, I've come to stumbling block in a bash script I've written. The bash script auto-fetches a file from an FTP server and does some processing on it. Heres the issue I'm having:
- I've added the script as a cron job
0 7 * * * /execute/my/script
- When the cron job is run, I get an email from root with a body that says "Unknown command".
Looking through the contents of the output when running the script, it seems the problem is this line:
500 Unknown command
The 500 Unknown command is sent from the FTP server to the FTP client. The weird thing is when you manually log into the FTP server using the ftp command, it will always give a 500 Unknown command for the first command you issue, then it will not display it again. For example:
# ftp XX.XX.XX.XX -i -n
Connected to XX.XX.XX.XX.

It does not effect the file transfer, but as I stated earlier it is tripping up cron. Anyone have any ideas on this? Thanks for your help
