extracting multiple variables from a filename.

hi all,

I'm trying to automate some tasks and while I've got the script itself working, I'm having difficulties with automatic file detection and associated variable setting...

for example, in a directory I've got several files... something along the lines of:

xis0_NAME_src.file
xis1_NAME_bkg.file
xis0_NAME_bkg.file
xis1_NAME_src.file

The NAME segment will change from use to use, but I'm looking to make the script automatically detect which file is xis0_*_src.file, which is xis0_*_src.file etc and attach it to each. So far I've tried using something along the lines of:

Code:
xis0_src=`find . -name "xis0*src*"`

but I end up with:

find: xis0_asd_src.pi: unknown option

Any pointers as to a more efficent way of setting this up? CHeers in advance!

UCF.CONF(5)						      Debian GNU/Linux manual						       UCF.CONF(5)

NAME
ucf.conf - site-wide configuration file for ucf SYNOPSIS
/etc/ucf.conf DESCRIPTION
The file /etc/ucf.conf is actually a Bourne Shell snippet included during the package build process, and hence you may put any shell direc- tive in that file (just make very sure you know what you are doing). All the variables have reasonable default values, and some may be overridden on a per run or a per individual basis by using environment variables, and all configurable variables can be overridden by options to the scripts themselves. The value of a variable can be set so: a) Defaults exist in the rules file. These are the values used if no customization is done. b) Some variables can be set in the config file /etc/ucf.conf. These values override the defaults. c) Some variables can also be set by setting a corresponding environment variable. These values override the config file and the defaults. d) Using script command line options. All configurable variables may be set by this method, and will override the other methods above. Configuration File options At the moment, the user modifiable variables supported are: DEBUG Debugging information: The default value is 0 (no debugging information is printed). To enable debugging output, set the value to 1. VERBOSE Verbosity: The default value is 0 (quiet). To change the default behavior, set the value to 1. conf_force_conffold Force the installed file to be retained. The default is to have this variable unset, which makes the script ask in case of doubt. This can be overridden by the environment variable UCF_FORCE_CONFFOLD conf_force_conffnew Force the installed file to be overridden. The default is to have this variable unset, which makes the script ask in case of doubt. This can be overridden by the environment variable UCF_FORCE_CONFFNEW conf_source_dir This is the directory where the historical md5sums for a file are looked for. Specifically, the historical md5sums are looked for in either the file ${filename}.md5sum, or the subdirectory ${filename}.md5sum.d/ conf_old_mdsum_file Force the historical md5sums to be read from this file, rather than defaulting to living in the source directory. Set- ting this option overrides settings in the environment variable UCF_OLD_MDSUM_FILE Files System-wide defaults are placed in /etc/ucf.conf, SEE ALSO
