Quickly re-execute a recent command in bash

! will expand to the last time you ran , options and all. It's a nicer alternative to ^R for simple cases, and it's quite helpful for those long commands you run every now and then and haven't made aliases or functions for. It's similar to command 3966, in some sense.
Sample Output
$ mysql --sigint-ignore --host <host> --user <user> --password --database <db> -e 'select * from contacts' > contacts.tab
# several lines later, database has been updated, need to re-download the table
$ !mysql
mysql --sigint-ignore --host <host> --user <user> --password --database <db> -e 'select * from contacts' > contacts.tab

What Others Think

It's supposed to say "last time you ran [command]". I have no idea why angle brackets aren't escaped.

This is handy. I also dig being able to reuse a value from a previous command. maybe something like nslookup www.commandlinefu.com curl !!:1
