[gentoo-user] OT: need text viewer with delete and multiple files

[Daevid Vincent]

After doing an emerge world (for example), I have a gazillion
/var/log/portage-logs to wade through to see if I need to follow any further
instructions (*sigh*)

Is there any recommended text viewer/editor whereby I can easily step
through the files (previous/next file), read .gz files, jump to the end of a
file, and most importantly, delete the current file?

'less /var/log/portage-logs/*' has most of these features, but it is sadly
missing the delete mode (at least I don't know it).

:n = next file
:p = previous file
:d = delete the file from a list (but not the file system)
Shift+G = jump to end of file

This can be an X app or CLI, however, I think CLI might be better, as
sometimes an emerge breaks things so X/KDE/Gnome/Etc won't start.

for x in /var/log/portage-logs/*; do
    less $x
    rm -i $x
done

Perhaps less with the LESSOPEN and LESSCLOSE environmental variables
set? Try this:

put the following in /root/portlogclose.sh

contents of /root/portlogclose.sh
---------------------------------
#! /bin/sh
rm -i $2
---------------------------------

chmod that 700

and do the following:

 # LESSOPEN="echo %s" LESSCLOSE="/root/portlogclose.sh %s %s" less /var/log/portage/*

It should prompt you everytime you move between files whether you want
the current file deleted or not. Just type Y or N and enter. The keys
won't echo onto the screen.

vim.  There's probably other (better) ways, but:

:!rm $filename
:n!

The first line tells vim to execute the shell command rm, you have to give it 
the filename, but that's displayed in the buffer anyway (or you can get it 
with ^G).  The second line tells vim to move to the next file, but to ignore 
the fact that you have a buffer opened that hasn't been written yet. :p goes 
to the previous file, if you haven't deleted it.

Actually thinking about it, you can do the same thing with less - !rm 
$filename works too.

Try:

:!rm %

"%" in a shell escape gets replaced with the name of the current file.

I knew there'd be some way of getting that, but I couldn't find it, thanks.  
Works with both vim and less too.

This looks interesting. A couple issues I notice..

Many of the logs use ANSI escapes, and most doesn't seem to display that,
how can I turn it on?

Is there a way to have it delete the current file and advance to the next
one?
