How to escape $?...

How to escape sequences like '$?', '?'  in command line?
I have a construct like this:

|Xdialog --yesno "really delete???\n%%f" 7 0;
sh -c "if [ $? == 0 ]; 
then kdesu 'rm -rf %f'; fi"

It works on the last Version of emelfm2, but not on the
newest.
1. There is no '???' in the Xdialog-message, tried
'\?': nothing
2. I had to replace '\n' to '\\n' for a line break,
this works
3. '$?' results in nothing

What can I do?
Thanks, Hans Durast

Someone proposed that escape chars be filtered from
commands. I guess that needs more thought.

> 3. '$?' results in nothing
0.1.6 will treat the ? as a wildcard, and so try to expand
$? into matching itemname(s), which in general would find
nothing.

apply the following, and rebuild

While we're at it, are there any other special-cases that

That won't help, for your test-case. emelFM2's command
processor is not a full-blown shell, it doesn't know about
things like $?.

To get access to shell parameters like $?, you need to run

 sh -c "Xdialog --yesno "the\\nresult" 7
0; echo $?" 

(which runs as expected after applying the patch from last
message).

BTW, if you want to prevent the "\" stripping
in 0.1.6, remove lines 960 to 978 from
.../src/command/e2_command.c

Hello,
I have a little Problem:
There is no menu-entry 'custom command' ('Eigener
Befehl', in my language),
in the drop-down-box of the configuration-menu.
Please help me on Version 0.1.7

thanks, Hans Durast

Hi!

'Custom command' means that you can type any command you
like in the
action row. You can also add your own command to any context
menu (i.e.
to actions or other) by clicking the action row and type
your own
command. 'Custom command' (Eigene Befehle) is only a
heading.

Is that the right answer? Maybe we should write is german
for better
understanding!?

Perhaps this is the better way, but one try in english: :-[
A picture says more than 1000 words?
Here is a screenshot,
http://fun-web.net/picture_library/1146928108Bi
ldschirmphoto1.png

You see, there is no menu entry 'Eigener Befehl' or
'custom command'
in the action row and this is the point.
Its not in the mainmenu and not in the submenu 'Befehl'.
It seems, that all other commands are complete.

thanks, Hans Durast

That's right because the custom commands are not internal
(of emelfm2) 
commands. If you want to add the same custom command like in
the context 
menu to the toolbar you have to define it again (twice).
Custom commands 
have no internal names (maybe custom_command.1) while i.e.
the refresh 
button is defined as the internal command
'Fenster.Aktualisieren'.

> It seems, that all other commands are complete.

All other internal commands! For example look at the context
menu 
'Aktionen - Kopieren'. It is defined as
'Datei.Kopieren'. And now look 
at the toolbar configuration. There is no command
'Aktionen.Kopieren' 
because the internal command is 'Datei.Kopieren' and this
item you will 
find.

Hope that will help you.

Regards
Ronny

The internal command (aka action) named <custom
command> is not needed any more.

It was necessary to allow user-defined commands to be
provided in the old form of action-list widget, where you
could only select, not enter anything custom, in the command
field.

Now you can enter a command, as well as select from the
actions menu. So just enter the command you want, and forget
<custom command> (though that should still work, if
you happen to have it lying around in a config file
somewhere, and that's why the name still exists in
translation files).

Tom

Oh yeah, great
Tom has understood my "Problem"
So as I understand your answer,
I had to put '<custom command>' (<Eigener
Befehl>) or nothing
into the action row and write my own sh-command right beside
it.
Both works, thank you.

Kind regards, Hans Durast

...on V0.1.8 + patch to copy files.
The button copy does it.

Very disappointing...

Hi all
But i have one:
it is not possible to change the access rights for more than
one file
marked in emelfm2 0.2.0.

Any solution?

Kind regards, Hans Durast

Why disappointing, it's actually a good rate 
but imho there are more bugs than ever in 0.2.0, this could
also be the
reason...

i haven't noticed your problem yet, but can confirm yet.
the 'apply to
all' button is broken, if you select multiple files and
click ok for
each, then it is ok.


regards, Uwe

Hmmm,  I didn't bang my head on that one.  It's good to
report these 
things, Tom is quick to fix them.

I have some enhancements I'd like to see:
  1): Add edit and edit_with to the context-menu of
executable scripts.
  2): Use the current selection for the 'mkdir'
suggestion, over-riding 
last creation.  In other words if branch-0.2.1 is selected,
suggest 
branch-0.2.1++, instead of last-creation++.
