How can I pipe output of bzip to mysql to restore data directly from bzipped file into a database
提问by Sasha
For making a dump of a database directly in bz2 format, I tried zipping the dump file directly using pipes, as follows:
为了直接以 bz2 格式转储数据库,我尝试使用管道直接压缩转储文件,如下所示:
mysqldump -u userName -p myDataBase | bzip2 -c > myDump.sql.bz2
I want to do a similar thing for restore. I can do this using 2 commands as follows: command 1:
我想为恢复做类似的事情。我可以使用 2 个命令执行此操作,如下所示:命令 1:
bzip2 -d myDump.sql.bz2
command 2:
命令 2:
mysql -u userName -p myDataBase < myDump.sql
Wanted:
Now I want to use the pipes to restore myDump.sql.bz2
to the database myDataBase

通缉:现在我想使用管道恢复myDump.sql.bz2
到数据库myDataBase

bzip2 -dc myDump.sql.bz2 | mysql -u userName -p myDatabase
- the -c option to bzip2 makes it send output to stdout, which you're already using when you created the dump.
bzip2 -dc myDump.sql.bz2 | mysql -u userName -p myDatabase
- bzip2 的 -c 选项使其将输出发送到 stdout,您在创建转储时已在使用该输出。
