Say, for some reason, you need to restore the entire contents of a single table from a HUGE mysqldump generated backup containing several tables. For example:
create table `baz`;
GIGS OF SQL YOU DON'T WANT;
create table `foo`;
A COUPLE THOUSAND LINES YOU DO WANT;
create table `bar`;
MORE SQL YOU DON'T WANT;
With a little dash 'o ruby, you can extract just the part you want:
$ ruby -ne '@found=true if $_ =~ /^CREATE TABLE `foo`/i; next unless @found; exit if $_ =~ /^CREATE TABLE (?!`foo`)/i; puts $_;' giant_sql_dump.sql > foo.sql
$ cat foo.sql
create table `foo`;
A COUPLE THOUSAND LINES YOU DO WANT;
You can then easily restore that entire table:
$ mysql mydatabase -e 'drop table foo'
$ mysql mydatabase foo.sql
