Full Discussion: fork multiple shells
Top Forums Programming fork multiple shells Post 302190675 by mariaro on Wednesday 30th of April 2008 07:59:25 AM

I'm rewriting my post... It seems it got lost somehow.

Check the line while(--count). The "While" loop will exit when count is 1, as --count is evaluated to 0, so the child from childpids[0] isn't killed.

You can simply replace the "while" line with:
for(count-=1; count >= 0; count--)

Best regards!

afile

AFILE(1)						      General Commands Manual							  AFILE(1)

NAME

       afile - display type and creator of Apple Macintosh files (netatalk format)

SYNOPSIS

       afile [ -a ] file ...

DESCRIPTION

       afile  displays	the  name  and Macintosh type and creator of the file arguments. Tests whether the file is an AppleDouble header, in which
       case it checks the corresponding data fork exists, or assumes it is a data fork in which case it looks for the corresponding AppleDouble to
       find the type/creator information.

       afile does not look at any of the extension mapping files such as AppleVolumes.system.

OPTIONS

       -a     Include directories and data files of unknown type (i.e. without corresponding AppleDouble) in output.

DIAGNOSTICS

       returns exit status 0 if all files have a corresponding valid  .AppleDouble header or data fork, or 99 for bad command line options. Other-
       wise it returns the following error code relating to the last invalid file.

       1  file doesn't exist
       2  file is unreadable
       3  file is directory
       4  file is AppleDouble without data fork
       5  file is AppleDouble with unreadable data fork
       6  file is data fork without AppleDouble
       7  file is data fork with unreadable AppleDouble
       8  file is data fork with short AppleDouble
       9  bad magic in AppleDouble
