[Techtalk] anyone know of a simple text viewer?

[Meryll Larkin]

Weird.  The first thing I thought was :

cat, head, tail.

for f in *.txt; do
   echo "${f}:"
   cat $f |grep -v "^$" | head -n15
   echo "-----------------"
   echo 
done

No tail in this one but it depends on what you are looking for.
For example, if you know you need to see the last few lines of a file.

Well, I'm a commandline girl so I usually just do something like
less *.txt
which shows each file in the current terminal window.
Admittedly, less has an annoying habit of exiting if you type q
to get out of the current file, so you have to use :n to jump to
the next file. It's a little friendlier to use the same shell loop
you quoted above:

for f in *.txt ; do less "$f" ; done

Less is so much faster than opening a GUI window for each file
(is part of why I like commandline tools).

If you want it in a separate window, so (as you mention) you can
close the window to quit viewing any more files, you could open it
in another terminal:

xterm -e 'for f in .??* ; do less "$f" ; done'

(or use your favorite terminal if not xterm).

But I guess I'm not entirely clear what your goals are. What
improvements were you looking for over the leafpad solution?
Faster? Better UI for scrolling through the file?
