psiclean

psiclean(1)															       psiclean(1)

NAME

       psiclean - delete files in the PSI temporary directories

DESCRIPTION

       The psiclean command finds a job name by scanning the input file for a keyword assignment of the form

	  DEFAULT:FILES:DEFAULT:NAME = string

       It  then  goes through all of the machine's temporary directories and deletes all files of the form string.*.  In previous versions of psi-
       clean , temporary directories were assumed to be of the form

	  /tmp[0-9]/$user

       In this version of psiclean , we get the names of the temporary directories from the user input file by looking for  volume  paths  of  the
       form

	  DEFAULT:FILES:DEFAULT:VOLUMEi = string

       It is essential that users see to the removal of their scratch files as soon as their job completes, because temporary directories are usu-
       ally a shared resource and there is not necessarily an automatic way for files to be deleted from these areas.  Thus, the last command  run
       after a job has finished should be the psiclean command.

       The user must take care to follow certain conventions when choosing filenames.  Any files which are to be kept after a job completes should
       not be kept in the default temporary directories.  The FILES input must be used to specify other locations for the specific files which are
       to  be kept.  psiclean will ignore files which are specifically listed by number (e.g., PSIF_CHKPT ) in the FILES section.  Files which are
       not needed after the run should use the default path given in the input file.  Otherwise, these files will remain on the  system  and  will
       impede other jobs.

EXAMPLE

       Suppose the PSI temporary directories contained the following subdirectories and files:

       /tmp1/cpuhog:
       -rw-r--r--  1 cpuhog	 14492 Jun 11 16:48 dicubane.30
       -rw-r--r--  1 cpuhog	187320 Jun  8 17:20 diketene.34
       -rw-r--r--  1 cpuhog	 16384 Jun  7 19:17 o4big.30
       -rw-r--r--  1 cpuhog	 16384 Jun  7 19:17 o4.30
       -rw-r--r--  1 cpuhog	974848 Jun  7 18:41 o4.34

       /tmp2/cpuhog:
       -rw-r--r--  1 cpuhog	 14492 Jun 11 16:48 dicubane.30
       -rw-r--r--  1 cpuhog	187320 Jun  8 17:20 diketene.34
       -rw-r--r--  1 cpuhog	 10904 Jun  7 18:50 o4big.30
       -rw-r--r--  1 cpuhog	 10904 Jun  7 18:50 o4.30
       -rw-r--r--  1 cpuhog	973752 Jun  7 18:41 o4.34

       /tmp3/cpuhog:
       -rw-r--r--  1 cpuhog	 14492 Jun 11 16:48 dicubane.30
       -rw-r--r--  1 cpuhog	187320 Jun  8 17:20 diketene.34
       -rw-r--r--  1 cpuhog	  8192 Jun  7 19:17 o4big.30
       -rw-r--r--  1 cpuhog	  8192 Jun  7 19:17 o4.30
       -rw-r--r--  1 cpuhog	966656 Jun  7 18:41 o4.34

       Let's also say that the user cpuhog is in a directory which contains an input file which has the following line in it:

       DEFAULT:FILES:DEFAULT:NAME = "o4"

       If  the user cpuhog now executes the psiclean command, then the o4 files in the temporary directories would be deleted, leaving the follow-
       ing files:

       /tmp1/cpuhog:
       -rw-r--r--  1 cpuhog	 14492 Jun 11 16:48 dicubane.30
       -rw-r--r--  1 cpuhog	187320 Jun  8 17:20 diketene.34
       -rw-r--r--  1 cpuhog	 16384 Jun  7 19:17 o4big.30

       /tmp2/cpuhog:
       -rw-r--r--  1 cpuhog	 14492 Jun 11 16:48 dicubane.30
       -rw-r--r--  1 cpuhog	187320 Jun  8 17:20 diketene.34
       -rw-r--r--  1 cpuhog	 10904 Jun  7 18:50 o4big.30

       /tmp3/cpuhog:
       -rw-r--r--  1 cpuhog	 14492 Jun 11 16:48 dicubane.30
       -rw-r--r--  1 cpuhog	187320 Jun  8 17:20 diketene.34
       -rw-r--r--  1 cpuhog	  8192 Jun  7 19:17 o4big.30
