parsing filename and grabbing specific string patterns
Hi guys...Wow I just composed a huge post and it got erased as I was logged out automatically
Anyways I hope someone can help me out here.
So the task I'm working on is like this
I have a bunch of files that I care about sitting in a directory say $HOME/files

Now my job is to go and loop over all these files and then grab parts of each filename and check if the parsed string exists in a parameter that is
passed to the script say $4

The filename parsing has the following rules

1: testfile_string1_string2_20100232to201130203.csv
parsed value should be "string1_string2"

2: testfile_string3_string4.csv
parsed value should be "string3_string4.csv"

3: testfile_string5_string6_string7_20113203to20110423.csv
parsed value should be "string5_string6_string7"

So the idea here is to grab the part of the filename after the first "_" upto a digit "20103232" eg 1 , eg3
Or the end of the string in case numeric values aren't there eg 2

I've been trying all day but I'm not able to find an answer for this
I'ld appreciate if one of you experts would help me out.

Thanks
Ruka

tixutils

Utils(n)						       Tix Built-In Commands							  Utils(n)

__________________________________________________________________________________________________________________________________________________

NAME

       tixUtils - Utility commands in Tix.

SYNOPSIS

       tixDescendants pathName
       tixDisableAll pathName
       tixEnableAll pathName
       tixPushGrab ?-global? window
       tixPopGrab
_________________________________________________________________

DESCRIPTION

       tixDescendants pathName
	      Returns a list of all the descendant widgets of pathName plus pathName itself.

       tixDisableAll pathName
	      Disables pathName and all its descendants.

       tixEnableAll pathName
	      Enables pathName and all its descendants.

       tixPushGrab ?-global? window
	      The  tixPushGrab	and  tixPopGrab commands allows you to perform "cascade-grabbing". tixPushGrab calls the grab(n) command on window
	      and saves window on a grabbing stack.

       tixPopGrab
	      tixPopGrab pops the top-most element from the grabbing stack and release its grab. If the grabbing stack is not empty, then  tixPop-
	      Grab will execute grab(n) on the current top-most element in the grabbing stack.

NOTES

       Some  Tix  widgets  (for  example,  tixComboBox and tixPanedWindow) grabs the screen on certain occasions using tixPushGrab and tixPopGrab.
       Therefore, if you need to grab the screen when these widgets are present, you should also call tixPushGrab and tixPopGrab in place  of  the
       Tk grab and grab release commands. Otherwise, the behavior of these widgets may be undefined.
