Shell脚本创建新的SQL转储

Question

I am currently using MAMP pro and i want to create a simple terminal script (or a .bat file like on the PC) which allows me to create a sql dump (where i go in and preconfigure the database name) and it automatically creates me the .sql file.

This is what i know so far:

1: The script should first visit cd /applications/MAMP/library/bin

2: When it in that directory, it should run the following

./mysqldump -u root -p databaseName > /Applications/MAMP/htdocs/website/db.sql

Finally, in that directory, when i click the script, it should not replace the older file, but create a new one, maybe just add the date or a integer after it.

Is that possible?

Apologies, i have no idea the best way of doing this.

Thanks in advance.

Answer 1

You can have this:

#!/bin/sh
TS=$(exec date '+%s')
cd /applications/MAMP/library/bin && \
    ./mysqldump -u root -p databaseName > "/Applications/MAMP/htdocs/website/db.$TS.sql"

It would create files in the form of db.(timestamp).sql .

If you want to have other forms, just changhe the date command. '+%s' specifies the format to produce which is the timestamp. You can see other formats with date --help or man date .

Answer 2

Just a variation on the other answer (vote for it!). You don't have to change directory to execute mysqldump :

#!/bin/bash
TS=$(exec date '+%s')
/applications/MAMP/library/bin/mysqldump -u root -p databaseName \
                  > "/Applications/MAMP/htdocs/website/db.$TS.sql"

Please beware that you have both /Application and /application directories. Depending your FS case sensitivity this might be an error.

Answer 3

Are you using the OSx?

#!/bin/bash
cd /applications/MAMP/library/bin && mysqldump -u root -p databaseName >   /Applications/MAMP/htdocs/website/db.sql

After this, you'll need set the permission to your script:

chmod +x your_script_file

Now, you can call...

./your_script_file

or

sh yout_script_file

If you want to replace the old file, this command will do this, because the new file name is the same the older file name
