Mount/unmount your truecrypted file containers
This should automatically mount it to /media/truecrypt1. Further mounts will go to /media/truecrypt2, and so on. You shouldn't need sudo/su if your permissions are right. I alias tru='truecrypt' since tr and true are commands. To explicitly create a mount point do: tru volume.tc /media/foo To make sure an GUI explorer window (nautilus, et al) opens on the mounted volume, add: --explorer To see what you currently have mounted do: tru -l To dismount a volume do: tru -d volume.tc. To dismount all mounted volumes at once do: tru -d Tested with Truecrypt v6.3a / Ubuntu 9.10
