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:
With a little dash 'o ruby, you can extract just the part you want:
You can then easily restore that entire table:
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
