Thanks for the reply, and the input. I used the method you suggested - running the "ps" inside the while loop - and it worked. What I don't understand is why this did not work in my original script as within the while loop, there is the call for the command substitution:
Prehaps this is highlighting gaping holes in my knowledge
I am having a problem with awk when I run it with a loop. It works perfectly when I echo a single line from the commandline. For example:
echo 'MFG009 9153852832' | awk '$2 ~ /^0-9]$/{print $2}'
The Awk command above will print field 2 if field 2 matches 10 digits, but when I run the loop... (5 Replies)

HTTPD(8) httpd HTTPD(8)NAME
httpd - Apache Hypertext Transfer Protocol Server
SYNOPSIS
httpd [ -d serverroot ] [ -f config ] [ -C directive ] [ -c directive ] [ -D parameter ] [ -e level ] [ -E file ] [ -k start|restart|grace-
ful|stop|graceful-stop ] [ -R directory ] [ -h ] [ -l ] [ -L ] [ -S ] [ -t ] [ -v ] [ -V ] [ -X ] [ -M ] [ -T ]
On Windows systems, the following additional arguments are available:
httpd [ -k install|config|uninstall ] [ -n name ] [ -w ]
SUMMARY
httpd is the Apache HyperText Transfer Protocol (HTTP) server program. It is designed to be run as a standalone daemon process. When used
like this it will create a pool of child processes or threads to handle requests.
In general, httpd should not be invoked directly, but rather should be invoked via apachectl on Unix-based systems or as a service on Win-
dows NT, 2000 and XP and as a console application on Windows 9x and ME.
OPTIONS -d serverroot
Set the initial value for the ServerRoot directive to serverroot. This can be overridden by the ServerRoot directive in the configu-
ration file. The default is /etc/httpd.
-f config
Uses the directives in the file config on startup. If config does not begin with a /, then it is taken to be a path relative to the
ServerRoot. The default is conf/httpd.conf.
-k start|restart|graceful|stop|graceful-stop
Signals httpd to start, restart, or stop. See Stopping Apache httpd for more information.
-C directive
Process the configuration directive before reading config files.
-c directive
Process the configuration directive after reading config files.
-D parameter
Sets a configuration parameter which can be used with <IfDefine> sections in the configuration files to conditionally skip or
process commands at server startup and restart. Also can be used to set certain less-common startup parameters including -DNO_DETACH
(prevent the parent from forking) and -DFOREGROUND (prevent the parent from calling setsid() et al).
-e level
Sets the LogLevel to level during server startup. This is useful for temporarily increasing the verbosity of the error messages to
find problems during startup.
-E file
Send error messages during server startup to file.
-h Output a short summary of available command line options.
-l Output a list of modules compiled into the server. This will not list dynamically loaded modules included using the LoadModule
directive.
-L Output a list of directives provided by static modules, together with expected arguments and places where the directive is valid.
Directives provided by shared modules are not listed.
-M Dump a list of loaded Static and Shared Modules.
-S Show the settings as parsed from the config file (currently only shows the virtualhost settings).
-T (Available in 2.3.8 and later)
Skip document root check at startup/restart.
-t Run syntax tests for configuration files only. The program immediately exits after these syntax parsing tests with either a return
code of 0 (Syntax OK) or return code not equal to 0 (Syntax Error). If -D DUMP_VHOSTS is also set, details of the virtual host con-
figuration will be printed. If -D DUMP_MODULES is set, all loaded modules will be printed.
-v Print the version of httpd, and then exit.
-V Print the version and build parameters of httpd, and then exit.
-X Run httpd in debug mode. Only one worker will be started and the server will not detach from the console.
The following arguments are available only on the Windows platform:
-k install|config|uninstall
Install Apache httpd as a Windows NT service; change startup options for the Apache httpd service; and uninstall the Apache httpd
service.
-n name
The name of the Apache httpd service to signal.
-w Keep the console window open on error so that the error message can be read.
