You may need to copy (using the cp command) to use the examples listed in these directories.

What happened to CRSP and COMPUSTAT!?
Visit the WRDS utility online instead (it's much easier to use, and a much fuller collection than we've had in the past (ex. Census data, Historical, not just recent (financial) datasets)
https://wrds.wharton.upenn.edu/
A license to use the web interface is required, and approval locally through the School of Management, but the process for new accounts is well-automated.
Editors
vi
emacs
pico (now upgraded to the better 'nano') - type pico at the command line or pico filename
and start editting. Don't forget to (Ctrl-W) Writeout to save your changes to th file you edit.
Running SAS
- Create progname.sas using your choice of Unix editors (see Common Unix commands)
- Type:
sas progname
or
sas progname.sas
To examine the results open up progname.lst using your choice of editors
for example
pico progname.lst
To examine whether there are errors that occured when sas was interpreting your sas statements, examine the LOG file
pico progname.log
(to be added soon --Rhansen 19:36, 8 February 2007 (EST))
SAS Narrative document (an example of running a few simple SAS program examples on Unix)
Other SAS on Unix wiki pages
Common SAS with X option configurations
Running Matlab
To startup (without X) type
matlab -nodisplay
at the command prompt
To leave matlab type
quit
If X is enabled on your local machine Simply typing
matlab
at the command prompt is the usual way to start matlab. Otherwise, type
matlab -h
to see other options for startup.
Further information about the product can also be found at the vendor's site
Running ANSYS
Ansys is currently not installed on Cruncher though there are plans to do so.
Programming (compilers, libraries)
Fortran
/opt/SUNWspro/bin/f90 fortranprogname.f
will produce an a.out file (To then run the program, you may need to set the a.out file as executable)
chmod u+x a.out
Then you may type
./a.out
or
./a.out arg1 arg2
if the program require command line arguments as input, or type
./a.out <infilenm
(if the program requires/processes an input data file on standard input
c++
gcc
PERL perl ?
Misc Utilities
Passwords
Changing my password passwd
Samba password sambapasswd (? - --Rhansen 19:51, 8 February 2007 (EST) )
or
smbpasswd
Miscellaneous commands
move2data filename - moves a copy of filename to a support repository (so that those staff on the support team can see your file directly without requiring root user intervention.

Space, resource constraints, large jobs
Policies
- for disk space allocation - guiding principle: 'equitable and efficient' methods for quota setting
User area quota guidelines
| User | Initial | at request | upper limit |
| Undergraduates | 5Gb | up to 10Gb with justification | up to 20Gb with faculty endorsement |
| Graduate students | 5Gb | up to 20Gb with justification | up to 100Gb with faculty endorsement |
| Faculty | 20Gb | up to 50Gb with justification | beyond 100Gb, discussed with Jim Wolf, possibly others |
Requests should be considered at 5, 10 and 20Gb increments (not micromanaged).
A committee of active Cruncher users plans to meet each year, December during finals week to assess policy unless remaining space in user space (totl available = 500Gb) is critically low. The committee will consider purchasing more space (currently costing ~$5 per Gb) or reassessing quota policy if needed.
- for archiving and backup commitments
Backups for the entire user space done daily (incremental versus full as needed based on activity). Archiving once at the end of every semester (Spring, Summer, and Fall).
Procedures
(for new accounts, account closure, quota increase, heavy computation time-slot reservation) - (to be determined, though web forms, or formalized procedures are planned as charges may be incurred for very large space requirements (necessary additions to the current configuration of the machine))
Web hosting and Email
Not available on Cruncher. (And currently there are no plans to make such functionality available. --Rhansen 19:41, 8 February 2007 (EST))
