[SOLVED] What are the 'variables' and what do they mean?

[Snowhog]

Cryptic, no?

Okay, this is what I mean. The 'default' command (GUI) in Kubuntu Jaunty to launch Kate is:

kate %U

What does the %U mean? And I know there are others. So where can one find out what they are and what they mean?

Re: What are the 'variables' and what do they mean?

From the KDE User's Manual:

26.1.3
The Exec option in .desktop files
Following the command, you can have several place holders which will be replaced with the actual values when the actual program is run:
%f A single file name; used when dropping file on icon, or with file associations.

%F A list of files; use for applications that can open several local files at once.

%u A single URL: if the app can handle e.g. FTP or HTTP URLs itself, otherwise KDE.

%U A list of URLs; will download the file first and pass a local file to the app (!!)

%d The folder of the file to open; useful if app needs to have file in current working directory.

%D A list of folders, not very practical.

%i The icon; --icon option; KDE app will use icon from Icon= line in taskbar.

%m The mini-icon; legacy.

%c The caption; --caption option; KDE app will use name from Name= line in taskbar.

Examples: Exec line: ksirc %i, Command executed: ksirc --icon ksirc

Exec line: cd %d; kedit $(basename %f), Command executed: cd /tmp; kedit file.txt

Re: What are the 'variables' and what do they mean?

Thank you. However, while the %c 'looked' promising, it doesn't do what I want. Here is what I have in
K Menu > Applications > Utilities:

Name: Kate - ROOT
Description: Advanced Text Editor [ROOT]
Comment:
Command: kdesu kate

In this way, Kate launches 'as root' after providing my password, with an 'untitled' blank document (the default behavior). The Title Bar of the running application shows: Untitled - Kate

Editing the entry to add the %c to the command - kdesu kate %c - results in Kate launching 'as root' after providing my password, with a *named* blank document called Kate - ROOT. The Title Bar of the running application shows: Kate - Root - Kate

What I want, is to have Kate launch with an Untitled blank document, but have the Title Bar show Kate - ROOT

kdesudo 'kate --caption "Kate - ROOT"'

Should do that

Re: What are the 'variables' and what do they mean?

YES! That did it. Thank you SO much!!

That was included in the reply from GreyGeek:

%c The caption; --caption option; KDE app will use name from Name= line in taskbar.

But I only tried the %c.

Thank you again. One more 'minor' issue solved.

Re: What are the 'variables' and what do they mean?

I was also wondering what those meant. The other day I took a look at Google Chrome BETA command and I saw that "%U" at the end. Well, now I know xD
