ubuntu - how to zip the output of the mysqldump command? -


i have cron with

#!/bin/sh  #string representation current day day=$(date +%y%m%d)  #archive db content /usr/bin/mysqldump --opt --host=db_host --user=db_user --password=db_pass db_name | /bin/gzip -c -9 > ${day}_db_name.gz

which runs fine. however, create zip file instead using zip compression.

i tried with

/usr/bin/mysqldump --opt --host=db_host --user=db_user --password=db_pass db_name | zip -q -9 > ${day}_db_name.zip

and result archive file named "-" inside. question how can change name previous command generated, 20130725_db_name?

it says here zip , input , pipeing , "streaming input , output" but, unfortunately, that's me understand
