Assuming you are using ksh or bash, and if your config file contains just shell assignment statement like

Code:
working_directory=/usr2/stuff/images
output_type=".png"
geometry="640x480"
qual=80

then you can source (sometimes called dotting in) the file. For instance, if the above exists in the file xxx.cfg in your bin directory, then the script(s) that need it can source it like this:

Code:
. ~/xxx.cfg

Sourcing a file (in Kshell or bash) causes the shell to open the named file and parse the contents as though they were a part of the script that it is executing. It is possible to put more than just assignment statements in the file being source; any valid shell statement can be included, but that's moving beyond the topic of this thread.

If your configuration file has a different format, or you are not using ksh, bash or a shell that supports sourcing like this, then as CodeManiac indicated please post more information.

NAME

       surfraw-update-path - updates PATH in shell config files

SYNOPSIS

       surfraw-update-path [-add] [-remove] [-check] [-sys] [-all] [-help] [-shell=SHELL]

DESCRIPTION

       surfraw-update-path adds the surfraw elvi directory (/usr/lib/surfraw) to your PATH in your shell's config file.

       Currently it supports bash, sh, csh, tcsh, ash, dash, ksh, pdksh, zsh, rc, and es

       Don't forget to login again or source your login files for it to take effect.

OPTIONS

       -check
	   Checks to see if the surfraw config code is present.  This is the default.

       -add
	   Adds the surfraw config code.

       -remove
	   Removes the surfraw config code

       -sys
	   Updates the system-wide shell config instead of the user.  Must be done as root.

       -shell=SHELL
	   Selects the shell to configure. Defaults to the value of the $SHELL environment variable.

	   Currently supported shells are:

	   sh, ash, bash, dash, csh, tcsh, ksh, pdksh, zsh, rc, and es.

       -all
	   Attempts to configure the startup files for all known shells

       -help
	   Gives a usage message

RETURN VALUE

       -check returns 0 if the surfraw code is present in the file, 1 if it is not found, or 2 on error.

       All other options return 0 on success, or 2 on error.

ENVIRONMENT

       SHELL
	   Used to determine which shell to configure, if -shell is not given.

       HOME
	   Used to find users config files.

       ENV Used by posix-compliant shells to specify a startup rc file.

       ZDOTDIR
