thank you ibidem,

I was was leading to the idea that maybe we should add toybox to our 'standard puppy' like aborigonal and others have done to extend some commands without having to use the 'full' command due to lack of functionality with the current busybox's version of a command. It may even allow us to remove some of the full commands we use now.

Alternately, the busybox group maybe need to revisit it's command set and extend a number of them with what users actually now need to have.

My apologies technosaurus for taking your ropic off-topic.

regards to all

What are the BB-NOTUSED applets? Currently on Debian, and I also use a pure busybox system (ie busybox, no gnu coreutils, no fileutils, no utils-linux, no extra text editor, no gnu sed, no gawk, ...), so I can't check atm.

Am a fan of busybox modprobe , its missing the -D --show-depends option i think . I hate modprobe[-FULL] !

Some are scripts to adjust vars ie reboot, poweroff, df , calling busybox applets in them .

(bb=busybox)
bb modprobe (without "simplified modutils") has -D since at least 1.20.2.
...Does Barry disable "simplified modutils" ?

sh I can see the reason for.
man is replaced with a script + browser (not my own preference, but...)
lsmod I see no logic to: neither bb nor standard has any options.
similar with sleep;
for rmdir bb lacks "--verbose".
for head bb lacks long options and metric units.
...

As I understand it... Puppy`s BusyBox isn`t compiled for Puppy.
So Barry disables the BusyBox links and uses the exec. files instead.

BusyBox could be built with the full exec. files instead of the trimmed down ones.
And probably many other apps. could be included; file browser, media player, etc.

The biggest difference is to configure with :
Prefer applets
Standalone shell
Run nofork applets directly

There are several options to prefer speed over size, desktop options etc...

Its also useful to change some applets to nofork ... mknod as nofork can cut boot time in half.

Hi.

Me grouching again.

Another thing: the busybox cal function always begins the week on Mondays.
I believe half the world finds it less confusing when their week begins on a Sunday.

Maybe the code for busybox cal is a few lines of code shorter that way, but what's
the motive behind ignoring the Christian tradition of beginning the week on a Sunday?
Annoying people?

No one with even a small exposure to social sciences -- better still: nobody tactful --
would have done that.

Developers : please re-instate the full cal in the next Puppy or in your next derivative.

My 2 cents. BFN.

Here in Germany, the first day of the week -by law- is Monday. This was probably done to clear up a glaring inconsistency in modern Christianity -namely, if one is supposed to observe the 'Sabbath', why is Sunday the Holy Day? Having Monday as the first day of the week makes Sunday the last day of the week.

Maybe it depends on the locale parameters that you use?
Still, the real cal offers more choices...

Hello Smile!

Speaking of cal, I'm completely lost when I see one of those calendars beginning the week with Sunday. Therefore, I usually patch busybox cal to display Monday as the first day of the week (sorry, no choice of Sun or Mon - not a C-programmer Embarassed ), like:
Code:

I don't use cal , used it in /sbin/init to compute variables for scheduled file system check .

Really horror to use cal in scripts with that "Ooh the poor not paying anything user needs a pretty output" .

one month one line --option

like -m for machine readable

2013 06:June 01:watday 02:disday 03:dongsday ...

would be really helpful
