Hi Friends, I have a tuff time with regular expressionss. Please let me know how to make this happen as it consumed lots of my time but in vain. Here is the sample text file i need to match for. I need to search for pattern1 removed, if it matches then search for pattern types either SE\ or dcfm-derby-dataload.sql not both. Similarly i need to search for pattern2 added and if it matches then search for either dcm-postgres-schema.sql or migrate\. Here i need to print files(dcm-postgres-schema.sql) and directories(migrate\) separately if it matches for removed and if it matches for added separately. Please help me.
Output must be like, i should be able to print both the lines:
---------[ removed ]---------------|----------------------------------
SE\ 2008-11-01 vbhupati |-
---------[ removed ]---------------|----------------------------------
dcfm-derby-dataload.sql vo+|-
.
.
.
-----------------------------------|---------------[ added ]----------
-| dcm-inm-postgres-schema.sql T0+
-----------------------------------|---------------[ added ]-----------
-| dcm-postgres-dataload.sql 23T08:+
.
.
.
Please help me. Thanks, nmattam

Hi.
If you have access to command glark, you can do this from the command line. Here is a short example of glark on your data:
producing:
Briefly, this says that matches must occur within one line of each other. The -a means "and", the -o means "or". Line 5 is printed because it is within one line of matched line number 4.
The two cases are separated here to avoid (some) confusion, but I think a master pattern could be created to handle it all in one pass over the data file. It would, however, not be easy to read. The glark code is written in ruby.
I installed it from the Debian (5, "lenny") repository. More information can be found at glark and glark | freshmeat.net
I don't see this as complicated from the viewpoint of regular expressions, but it is complex from the viewpoint of structuring decisions.
If you don't have access to glark, then you will probably need to use perl or awk. There are many experts on both here, so someone may be along shortly to help with that ... cheers, drl

Dear drl,
I appreciate your help, but i do not have access to glark. I appreciate if any one can help me with another possible solution.
Thanks, nmattam
