Triggering a Script Recursively With Different Parameter and in Different Process
Hi Every One
I have a Compilation Script name scomp which takes the Program name as the command line argument
I have around 10000 Programs to compile while each program takes around 10 mins to compile
i have written a Mass Compile script Scripts which takes the list of programs as input file and trigger the scomp for each Program in a for loop
Now the Problem is until compilation for one program is not finished it does not start the compilation for the next Program in my Mass Compilation Script
so to finish of all the 10000 Programs it take hell lot of time
so Is there any way that i can Trigger the scomp simultaneusly for many Programs at a time so the the overall compilation time reduces like creating one more process??
my Mass Compile Script is some thing like this
echo 'Enter file with list of programs :
'read INPUT
for I in $(cat $INPUT)
do
echo ${I}
/home/aixuser/scomp ${I}
done
I want to do this simultanesly for Programs given in Input file...

Hi,
I'm seeing the error vmunix: file: table is full in syslog.log.
Although changing the value of the kernel parameter nfile would make this error go away, how would I identify which process/application in the server is triggering this error? The server is a HP-UX B.11.11.
Thanks in advance! (1 Reply)

atfsit
atfsit(1) ShapeTools atfsit(1)
NAME
atfsit - A program to prepare files for version control
SYNOPSIS
atfsit [ -cFhfsmM ] [ -qad ] [ -Iflags ] [ -Rflags ] [ -tdirectory ] file1 ...
DESCRIPTION
Atfsit is a semi-intelligent program to prepare files for ShapeTools version control. This involves putting the correct type of headings
at the top of the file so that retrv will update a header and log changes in the file.
By default, atfsit will use default headers ``hard-wired'' into itself for each different file type that it ``knows'' about. (See below
for list of known file types).
If the -tdirectory option is specified, then atfsit will use ``.template.suffix'' files (where ``suffix'' is a suffix that atfsit ``knows''
about) found in directory. If a directory name is not specified on the command line, then the environment variable TEMPLATES is used. If
$TEMPLATES is not set, then the environment variable, HOME is tried.
The following template files are recognized:
Template NameFile Type
---------------------------------------
.template.c Standard C
.template.h C Include
.template.f Fortran
.template.shShell Script
.template.makeMakefile
.template.manManual
Atfsit is ``semi-intelligent'' in that it can guess the type of headers to put in the file by the type of file (C program, C include, make-
file, shell script, or manual). It determines the file type by looking at the name of the file. If the name of the file is ``Makefile''
or ``makefile'', then the file type is taken to be for make(1). The suffix after the last ``.'' in the file name is then used. The fol-
lowing table shows the suffixes that atfsit knows about:
Suffix File Type
---------------------------------------------
c C Program
F C Program (with compile flags)
h C Include
f Fortran
mk Make(1) file
sh Shell Script
csh Shell Script
[1-9] Manual (digits 1 - 9)
If the environment variable ``ATFSDIR'' is present, then atfsit will attempt to make a link from it to ``AtFS'' in the current directory if
the -I option is used and there is no directory called ``AtFS'' already, in the current directory. If the -I option is used and ``ATFS-
DIR'' is not specified in the environment, then a normal directory called ``AtFS'' will be created. This feature can be overrided with the
-d option.
OPTIONS
c Force file type to be ``Standard C''.
F Force file type to be ``Standard C''. Add a special header-line for recording of compile-time options in addition to the default
header. The inserted line has the form static char *ConfFlg = CFFLGS. CFFLGS must be a string value. As it is very inconve-
nient, to define the proper value of CFFLGS from the command-line, this feature is more intended to be used from within Make-
files.
h Force file type to be ``C Include''.
f Force file type to be ``Fortran''.
M Force file type to be ``Manual''. Note: If you also specify the ``Iflags'' option, atfsit will run vadm(1) to tell ShapeTools
what kind of comment string to use for the manual file.
s Force file type to be ``Shell Script''.
m Force file type to be ``Makefile''. Note that this does the same thing as the -s option does. It just prints a different mes-
sage.
t Do not use any Template files for the headers.
q Be quiet. Don't print out what is going on. Only error messages are printed.
d Do not attempt to make the directory ``AtFS''. See above for more info.
a Turn off auto guessing of file type.
Iflags Check In file. Run save(1) on the file with ``flags'' being passed onto save(1) as the command line arguments.
Rflags Run vadm(1) with ``flags'' as the command line arguments.
FILES
/tmp/atfsit* - temporary buffer
~/.template.* - template files to use as the header.

DIAGNOSTICS
Complains about the usual stuff. (i.e. - the specified file doesn't exist, or it can't read it...just things like that.)
