Top Forums Shell Programming and Scripting Error in finding the PID by grep and assigning to a variable Post 302739441 by duddukuri on Tuesday 4th of December 2012 08:01:41 AM

Thank you jim mcnamara for reply.
$! is returning the parent PID only, which is not full filling my requirement.

Once the parent PID is completed, SUB PROCESS will start and it will have a new PID.

I should grep the sub process PID in while loop & till the completion of sub processes i need to wait and then i should break from the loop

secon [-hVurtscmPRfLp] [CONTEXT] [--file] FILE [--link] FILE [--pid] PID DESCRIPTION
See a part of a context. The context is taken from a file, pid, user input or the context in which secon is originally executed. -V, --version shows the current version of secon -h, --help shows the usage information for secon -P, --prompt outputs data in a format suitable for a prompt -u, --user show the user of the security context -r, --role show the role of the security context -t, --type show the type of the security context -s, --sensitivity show the sensitivity level of the security context -c, --clearance show the clearance level of the security context -m, --mls-range show the sensitivity level and clearance, as a range, of the security context -R, --raw outputs the sensitivity level and clearance in an untranslated format. -f, --file gets the context from the specified file FILE -L, --link gets the context from the specified file FILE (doesn't follow symlinks) -p, --pid gets the context from the specified process PID --pid-exec gets the exec context from the specified process PID --pid-fs gets the fscreate context from the specified process PID --current, --self gets the context from the current process --current-exec, --self-exec gets the exec context from the current process --current-fs, --self-fs gets the fscreate context from the current process --parent gets the context from the parent of the current process --parent-exec gets the exec context from the parent of the current process --parent-fs gets the fscreate context from the parent of the current process Additional argument CONTEXT may be provided and will be used if no options have been specified to make secon get it's context from another source. If that argument is - then the context will be read from stdin. If there is no arugment, secon will try reading a context from stdin, if that is not a tty, otherwise secon will act as though --self had been passed. If none of --user, --role, --type, --level or --mls-range is passed. Then all of them will be output. SEE ALSO
