How to use temporary directory /tmp¶
Every UNIX machine has a /tmp directory used for temporary files. It is very important not to put important files in this directory because the operating system can erase them when they are not used for a while. It also not subject to snapshots or backups.
This disk space is not part of your personal quota.
We strongly recommend that you create temporary files used in your calculation in this directory and use the data output in your account.
