File systems

 

Each of the workstations, and the Convex (a low-end workstation) have a number (usually 2 or 3) of disks available for data storage purposes. The file systems are called /DATA/HOST_N where `HOST' is the computer name and N is the disk number. Some of these workstations and their disks are bookable by users. Others are all-user scratch disks which are wiped regularly, others are all-user longer term storage areas. For example, the data file system on the bookable disk on PUPPIS is /DATA/PUPPIS_3. For the Convex the first of the two all-user disks is /DATA/ATELES_1.

To find out what the status of all the available disks is, enter the command   

aipsdisks

at the Unix prompt level and you will be enlightened.

Under these top level file systems on each disk, are several more directories. These are `AIPS', `aips++', `miriad', and `other'. AIPS files go into the `AIPS' directory (AIPS will put them there for you when it creates them). The other directories are used appropriately.

For temporary storage of large data files on disk, you should use the `other' directory (except for files apropriate to the other standard named directories; do not clutter the `AIPS' directory with RPFITS files). Change to this directory with a command such as

cd /DATA/PUPPIS_3/other

You should then create a directory for your own use with a command such as

mkdir ehubble

(if you are less famous try something more appropriate) and then enter that directory with

cd ehubble

You can then use this area for your workspace.
