I have a script which connects to a remote server via SFTP and get some file from there. My script goes like this:

/usr/bin/sftp [email protected] <<EOF
lcd /dir1/dir2/dir3
cd /rsdir1/rsdir2/rsdir3
get file_pattern`date -d "last month" +%m%Y`.csv
EOF
rc=$?
        if [[ $rc != 0 ]]
           then
        echo "Error occured getting file and the script abended with error code $rc" `date "+%Y-%m-%d-%H.%M.%S"`
            exit 1
    else
    echo "Successfully transferred the file" `date "+%Y-%m-%d-%H.%M.%S"`
        fi

However, even if the script doesn't find the file with the pattern it goes to the else part of the script and gives me the output on the screen as

Connecting to remote.server.com...
sftp> lcd /dir1/dir2/dir3
sftp> cd /rsdir1/rsdir2/rsdir3
sftp> get file_pattern032014.csv
Couldn't stat remote file: No such file or directory
File "/rsdir1/rsdir2/rsdir3/file_pattern032014.csv" not found.
Successfully transferred the file YYYY-MM-DD-24HH.MI.SS

Any advices on what I might be doing wrong here?

You might want to take a look at lftp too instead of trying to script with sftp. It's not really meant to be used in that fashion. I show an example doing something like this using lftp here: unix.stackexchange.com/questions/88710/… –  slm yesterday

You got the right return code, sftp session executed correctly so the return code is 0.
You should use scp instead, it does not returns 0 if it fails to copy.

You could do something like : 

[email protected]:/rsdir1/rsdir2/rsdir3/file_pattern`date -d "last month" +%m%Y`.csv
local=/rsdir1/rsdir2/rsdir3

if scp -q $remote $local
then
    echo "Successfully transferred the file" `date "+%Y-%m-%d-%H.%M.%S"`
else
    echo "Error occured getting file and the script abended with error code $?" `date "+%Y-%m-%d-%H.%M.%S"`
    exit 1
fi
