Linux does things different obviously.


I think I learned that under SunOS (erm...a couple decades ago)... Which also worked under Slackware, Debian, etc...

I remember now . I was installing netbsd unix
on an old mac computer and I started
reading about unix.

Here's the reference

Visual Quickstart Guide
Unix Third Edition

by Deborah S. Ray and Eric J. Ray

Code:
If you use && to combine commands,
the system will run both in sequence but
run the second only if the first succeeds.
For example, you could use

mv  todolist  todolist.done  &&  touch todolist

to move your to-do list to a different file and
create a new to-do list.  If the first command
fails  (for example, because you don't have
permission to create a new file),  the second
command won't run.


With Puppy linux there isn't many permissions issues,
so nobody uses the double ampersand.
Now I understand the confusion.

Aha! That's a valid reason to have such a command, in addition to ";" (which runs regardless)

I learned something new today! Thanks Don!

Well, most people don't even use the command line any more, so...

I guess that I was aware that "&&" also worked, but because "&" is a "special character", I avoided it. From the error standpoint, I find that ";" is more well behaved -- and when it doesn't work, it doesn't do exceptionally strange things -- like backgrounding jobs... Wink

BTW, it rather looked like part of the problem was that characters we being "quoted" rather than being operators...

There's that whole goofy list of special characters, such as: "&" versus "\&" and what's the really goofy one..."\\\" which quotes "\" as a character (I _think_)? ("\" being the special character used for quoting, is difficult to "quote", so you have to "quote" it again...or is it twice more?)

Urgh!!!...

Mostly I see "&&" used after after tests. If using ";" it's just a new line of code....quite different.

Code:

[ "$1" = "" ] && echo "no arguments here" && exit

Version 0.9-3
See main post

Changelog
- New parameters to manage Pschedule from external apps
--> -e : edit a already defined command
--> -s : run silent. Do not show main window.

This makes it possible to use the Pschedule editor in other apps. Will be used by Pmusic 1.6.0

There was a bad install of pschedule in wary quickset 503.

I've warned shinobar
http://www.murga-linux.com/puppy/viewtopic.php?p=502377#502377

To prevent this from happening again, it might be helpful to
change the .desktop file
Code:

[Desktop Entry]
Encoding=UTF-8
Name=Pschedule task on time
Icon=mini-clock.xpm
Comment=Pschedule task on time
Exec=/usr/local/pschedule/pschedule
Terminal=false
Type=Application
Categories=X-SystemSchedule
GenericName=Pschedule task on time


I would suggest changing the line
Exec=/usr/local/pschedule/pschedule

to

Code:

Exec=/usr/local/bin/pschedule



That will force users to install properly or it won't work at all.

Using lucid puppy 5.2.......


I couldn't get pschedule 1.0.1 to show in French
so I had to stick with pschedule 1.0

_______________________________

Also I recommend that you change the name of
'fr_ca:french' to 'fr:french'

This will make the application show in French
without the need to create a link.

Thanks for this, one small problem, if I can call it that, the link buttons in the about box didn't work for me.
I added BROWSER="defaultbrowser" to the top of the pschedule script and that fixed it.

Localization does not work. In /usr/local/pschedule/pschedule $APPDIR should be replaced with $PROGPATH.

Thank you. Don570 complained about this ages ago, and I have simply forgotten. Sorry.
