Question

我有一个很大的mysql通用查询日志，如下所示：

110301  2:19:29  268341 Query       SELECT option_value FROM wp_options WHERE option_name = 'sidebars_widgets' LIMIT 1
             268341 Query       SELECT autoload FROM wp_options WHERE option_name = 'rewrite_rules'
             268341 Query       DELETE FROM wp_options WHERE option_name = 'rewrite_rules'
             268341 Query       SELECT option_value FROM wp_options WHERE option_name = 'rewrite_rules' LIMIT 1
             268341 Query       SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id WHERE tt.taxonomy IN ('category')  ORDER BY t.name ASC
             268341 Query       SELECT ID, post_name, post_parent FROM wp_posts WHERE post_type = 'page'
             268341 Query       SELECT * FROM wp_posts WHERE ID = 9191 LIMIT 1
             268341 Query       SELECT ID, post_name, post_parent FROM wp_posts WHERE post_type = 'attachment' AND post_parent = 9191
             268341 Query       SELECT * FROM wp_posts WHERE ID = 8805 LIMIT 1

我想使用AWK查找所有INSERT INTO语句？

Answer 1

gawk "/INSERT INTO/" query.log

我估计你会做额外的处理，否则如前所述，你真的不需要awk。

Answer 2

为什么选择awk？ grep更适合。

grep -i "INSERT INTO" filename.log

Answer 3

我会使用带-o选项的grep：

$ #with your input in /tmp/file
$ grep -O 'SELECT .*' /tmp/file
SELECT option_value FROM wp_options WHERE option_name = 'sidebars_widgets' LIMIT 1
SELECT autoload FROM wp_options WHERE option_name = 'rewrite_rules'
SELECT option_value FROM wp_options WHERE option_name = 'rewrite_rules' LIMIT 1
SELECT t.*, tt.* FROM wp_terms AS t INNER JOIN wp_term_taxonomy AS tt ON t.term_id = tt.term_id WHERE tt.taxonomy IN ('category')  ORDER BY t.name ASC
SELECT ID, post_name, post_parent FROM wp_posts WHERE post_type = 'page'
SELECT * FROM wp_posts WHERE ID = 9191 LIMIT 1
SELECT ID, post_name, post_parent FROM wp_posts WHERE post_type = 'attachment' AND post_parent = 9191
SELECT * FROM wp_posts WHERE ID = 8805 LIMIT 1

INSK INTO的awk general-query.log
