Question

I have the databases name in following format

username_databasename

Now I want to put separate database backups in username directory like

/backups/username/backup

How can I get the usernamae from that string

I also want that if string does not contain underscore (_) then the backup should go to

/backups/others/backup

You can do:

username=others
if echo $name | grep '_'; then
 username=$(echo $name | cut -d'_' -f 1)
