How can I list database names within a mysqldump file?

I have a large mysqldump and I need to create the databases before importing them one-by-one. How can I search and list only the database names using the linux or mysql terminal?

PROPOSED SOLUTION

DUMPFILE=mydump.sql
grep "^USE " ${DUMPFILE} | sed 's/;//' | sed 's/`//g' | awk '{print $2}'

EXAMPLE

# grep "^USE " dump.sql | sed 's/;//' | sed 's/`//g' | awk '{print $2}'

You could collect them in a variable (Note: You must escape the backquote)

# DBLIST=`grep "^USE " dump.sql | sed 's/;//' | sed 's/\`//g' | awk '{print $2}'`
# echo ${DBLIST}
