Supplying dynamic pattern (YYYYMMDD) as ftp mget pattern

Question

I am writing a script that supposed fetch today's files (about a dozen) from an FTP site using mget like so

ftp -n XX.XX.XX.XX <<END_SCRIPT
mget *20190703*
quit
END_SCRIPT

Ideally I'd do something like mget 'date +%Y%m%d' (apostrophe used in lieu of a literal backtick) but that's not possible. I'd appreciate any pointers

Answer 1

Below code segment should work: Kindly check.

event_date=`date +%Y%m%d`
ftp -n -i XX.XX.XX.XX <<END_SCRIPT
mget *${event_date}*
quit
END_SCRIPT

or you may look in below script: we use this script in production

event_date=`date +%Y%m%d`
lftp -p [port number] -u user_name,'password' sftp://ip <<HERE_DOC
cd file_directory
mget *${event_date}*
bye
