CMS unix environment

Upon logon to one of the above mentioned platforms, group login scripts are executed and several CMS customized environmental variables are set:

 
  		 $CMS_PATH     		 - root directory of the public area

  		 $CMS_LEVEL    		 - level old, pro, new or dev

  		 $CMS_VER      		 - version , , or

  		 $SRC           		 - CMS sources public checkeout directory

  		 $CMS_DB       		 - data base directory

  		 $CMS_LIBS     		 - directory for compiled libraries

  		 $CMS_LIBPATH  		 - library path used in linking

  		 $SCRATCH       		 - the user scratch directory

  		 $CMZ           		 - CMS CMZ source files directory (up to cms103)

The definition of some of these environmental variables depends on the CMS version old/pro/new/dev being active. The user can activate a given version via the following four commands:
cmsold
cmspro
cmsnew
cmsdev
The source code and the corresponding compiled libraries are kept in the directories owned by the pubzh account.
