Catching errors in LFTP Bash Script

Question

So I am trying to catch specific errors whilst transferring files using LFTP, but the problem is, I am unable to catch them due to calling the <<EOF to allow interfacing with the interactive shell.

The code I am using is as follows:

#Start backup procedure
lftp<<EOF
open ftps://$HOST || bye && #SEND MAIL CANNOT CONNECT TO SERVER (ERROR)
login $USER $PASSWORD || #SEND MAIL AUTH FAILURE (ERROR)
#Remove existing backups on FTP server
glob -a rm -r ./* || bye && #SEND MAIL FAILED (WARNING) TO REMOVE PREVIOUS BACKUPS
#Upload new backup to FTP server
lcd /var/opt/gitlab/backups
mput *.tar || bye && #SEND EMAIL (ERROR) FAILED TO UPLOAD FILES
bye
EOF

Obviously when bye is called the interactive session is closed, but nothing gets executed after the &&.

Anyone have any idea on how to do specific error catching like this?

have you tried using traps instead of the `||` and `&&` operators ? — Aserre, Oct 09 '17 at 11:20
I suspect you are going to need to turn to `Tcl/expect` to get that level of checking. — Mark Setchell, Oct 09 '17 at 12:59

You can use command grouping using parentheses:

open... || (shell send-mail; exit 1)
