Hi....Thanks for the reply
Hi,
sorry to say that I cant mention actual process names since it is confidential. Hope you will understand.
I am running some process XXXX, this process internally invokes some other process YYYY which is on demand process.
Now this on-demand process is creating temporary files in /tmp directory.The temp file name is like .<usrName><pidofOndemandProcess> (example: .root12456).
By using rm I am able to delete this temp file.
My doubt is do we have to remove these temp files with some cron entry only OR thie ondemand process which is creating these temp file only resposible to delete these files?? Generally in unix like platforms what would be the general way...? At least I couldn't find any clue from the code of this on demand process.
any help will be appreciated.
Thank you.
Regards,
Viswath

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
