Audacity Copy
I was getting an error when launching Audacity.
The error was:
“The system has detected that another copy of Audacity is running.”
However, Audacity wasn’t running at all. Not one process. It turned out to be just a locked file located in /var/tmp/audacity-[your-username].
All you have to do is delete the entire directory and rerun Audacity.
rm -rf /var/tmp/audacity=[your-username]/ |
Once deleted, Audacity starts right up with no issues.
Bash Variables
Here’s how to read Bash variables from another file.
Contents of config.sh
#!/bin/bash var1='thisisvariableone' var2='thisisvariabletwo' |
Call config.sh from another script.
#!/bin/bash source config.sh echo var1 echo var2 |
This is extremely helpful if you have multiple scripts using a common variable. You just to update one file instead of multiple files. All the other scripts will read and pick up the same variables from a config file. You can use this to setup your global variables.
MySQL Restore to another DB
In order to restore a MySQL database to another database, use routines and triggers.
mysqldump -p user -p --routines --triggers db1 > db1.sql |
To restore to another database, just use the normal command.
mysql -u user -p db2 < db1.sql |
