PSRCHIVE Administration Guide

Version Control

To use the current stable version of the PSRCHIVE system installation, simply run 
source $PSRCHIVE_SYSTEM/stable/share/psrchive_version
This script will modify your PATH environment variable and setup an alias command for version selection.

Continuing the example above, you might add the following to your .cshrc file: 

setenv PSRCHIVE_SYSTEM /nfs/pulsar/linux/psrchive
if (-f $PSRCHIVE_SYSTEM/stable/share/psrchive_version) then
  source $PSRCHIVE_SYSTEM/stable/share/psrchive_version
endif

After sourcing the psrchive_version script, a new alias of the same name will be available. With this command, it is possible to query the system version; e.g. 

psrchive_version
PSRCHIVE System: /nfs/pulsar/linux/psrchive Version: stable
and set the system version; e.g 
psrchive_version 6.1
After setting the system version, the PATH environment variable will be set accordingly.
