I downloaded less_458 to my LupuPlus_5.2.8. As you mentioned, the existing /usr/bin/less was a link to busybox.

Less only flashed on the screen for a fraction of a second when I tried it.

Code: Select all

# less my-documents/growisofs.txt 
less: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

This is the important bit:

Code: Select all

cd /usr/lib
 ln -s libncurses.so.5 libtinfo.so.5
 ln -s libtinfo.so.5 libtinfo.so

New version works fine for me, complete with bi-lingual menu entries! This one is a keeper I think.

The lack of libtinfo.so is not so much a specific Ubuntu oddity, some other distributions don’t provide it either. The default behaviour when building NCurses is not to produce a separate libtinfo.so. It is only done when adding the –with-termlib switch to the NCurses configure script when building NCurses.

I do agree that linking libtinfo.so explicitly is broken behaviour, as it will not exist with a default shared library build of NCurses.

The same issue can arise with libtic.so, which can also be built as a separate library from libncurses.so by use of the –with-ticlib switch.

Hi, step.

Can't you? Have you tried? Sixty-four--bit machines are advertised as being able to
run 32-bit programs without a sweat, are they not ?

And thanks for the thanks, of course! My pleasure!

BFN.

Cool less tricks

New users of less sometimes find that less doesn't behave exactly the way they
expect. If this is the case, don't despair. Less has an enormous number of options
(perhaps too many) which let you change the way it behaves. Chances are, there is a
way to make less do what you want. A complete description of all these features is in
the less man page, but here's a summary of some of the more popular ones.

Quit at end-of-file
To make less automatically quit as soon as it reaches the end of the file (so you don't
have to hit "q"), set the -E option.

Verbose prompt
To see a more verbose prompt, set the -m or -M option. You can also design your own
prompt; see the man page for details.

Clear the whole screen
To make less clear and repaint the screen rather than scrolling when you move to a
new page of text, set the -C option.

Case-less searches
To treat upper-case and lower-case letters the same in searches, set the -I option.

Start at a specific place in the file
To start at a specific line number, say line 150, use "less +150 filename". To start
where a specific pattern first appears, use "less +/pattern filename". To start at the
end of the file, use "less +G filename".

Scan all instances of a pattern in a set of files
To search multiple files, use "/*pattern" instead of just "/pattern". To do this from the
command line, use "less '+/*pattern' ...". Note that you may need to quote the "+/
*pattern" argument to prevent your shell from interpreting the "*".

Watch a growing file
Use the F command to go to the end of the file and keep displaying more text as the
file grows. You can do this from the command line by using "less +F ...".

Change keys
The lesskey program lets you change the meaning of any key or sequence of keys. See
the lesskey man page for details.

Save your favorite options
If you want certain options to be in effect whenever you run less, without needing to
type them in every time, just set your "LESS" environment variable to the options you
want. (If you don't know how to set an environment variable, consult the
documentation for your system or your shell.) For example, if your LESS environment
variable is set to "-IE", every time you run less it will do case-less searches and quit at
end-of-file.
