A shell loop can ask for the pattern, capture matching lines in a temp file, count the lines at the same time, and if any lines, turn you over to vi, pg, less in the temp file to view and play in the subset. When you exit the viewer, it asks you if you want to view again, and if not, loops. You can make any copies you want from inside the viewer.

Now, only a select few actually prefer the csh. The bash and ksh93 are much nicer and there are more experts to help.

PS: I use the ksh/bash 'set -o vi' option to do command recall, so I do not type commands over and over. I never even leave my home dir except inside (...) so I return automatically. It makes the history more valuable. I also save the history file occasionally where my tools can find it, and set a huge HISTSIZE of 32767. I consider one of the best CUI's.

NAME

       mprof-heap-viewer - GUI viewer for the logging profiler heap snapshots

SYNOPSIS

       mprof-heap-viewer file

DESCRIPTION

       mprof-heap-viewer GUI viewer for the logging profiler heap snapshots

       WARNING: this application is unfinished and experimental.  Nevertheless it should work, and bug reports are encouraged.

       This program decodes the contents of a logging profiler output file and locates all the heap snapshots inside it.  The user can then select
       each individual snapshot and decide to load it in memory and explore its contents.

       The GUI is organized to work on "object sets" (listed in a tree view on the left).  All operations are performed with a popup menu  on  the
       choosen set.

       Initially  the  sets are the heap snapshots (of course a heap snapshot can be considered a set of objects!).  For each set the GUI shows on
       the right a list that breaks it down by class (one row for each class).

       The user can then refine each set using a "filter", to select a subset.	Examples of filters are "all objects of class X", or "all  objects
       that reference an object of class X".  This way the user explores the sets breaking them down to subsets (each subset in the GUI is a child
       of its owner set on the tree view).

       Moreover the user can issue a "compare" operation between two arbitrary sets A and B, which will compute two subsets: "A - B" (the  objects
       of  A  which  are  not  in  B,  a subsect of A) and "B - A" (the reverse).  This can help in understanding what changed on the heap between
       garbage collections.
