Yesterday I was debugging a C project that stores a lot of data in the filesystem and in a MySQL database. And I found myself repeating the same commands everything I fixed something and restarted the application. Those commands where:
$ rm -rf debug_* $ rm -rf data && mkdir data $ mysql -u root -proot mysql> USE db_name; mysql> DELETE FROM table_name WHERE id > 0; mysql> quit
And believe me, after a while you get really fast at this… but it’s still unnecessary!!
So I decided to create a shell script called
clean.sh to automate this process. And, while the first commands are really straightforward, running MySQL commands, in a shell script, it’s a little bit more complex if you are not used to do it through the command line!
So, if you ever need to do something like this, here is my script:
#!/bin/bash # Clean data script rm -rf data \ && mkdir data \ && mysql -u root -proot -Bse "USE db_name;DELETE FROM table_name WHERE id > 0;" \ && rm -rf debug_* \ && echo "Cleaned!"
After saving your file with this content on it, you just need to give execution permissions and run it!
$ chmod 755 clean.sh $ ./clean.sh Cleaned!
And you are good to go…
PS: Your keyboard will thank you for that!
