Change konsole tab title from command line and make it persistent?

Question

How can I change the konsole tab title? By default, it\'s set to %u : %n, so it always changes automatically.

I can set it with:

qdbus org.

You may need to use this variant:

`echo -ne "\033]30;test change title\007"`


    $ konsole -v
    Qt: 4.8.6
    KDE Development Platform: 4.13.3
    Konsole: 2.13.2

I was never happy with setting the title for konsole windows, then I saw Tim's comment. This was a big improvement for me. Thank you, Tim!!

But that did not quite get me where I wanted to be.

I wanted to go beyond typing in the given command line example because I have a terrible memory and 3 weeks from now, I will not remember the character sequence of the variant.

I wanted to be able to create an alias that would allow me to do the following:

define an alias 'T' for my shell (tcsh in my case) so that I can enter:

    T titleName

and another alias 'DT' so that I can enter:

    DT titleName

The 'T' alias changes the window title to 'titleName' and the alias 'DT' changes the window title to '%d titleName' where %d is the directory name.

It took some experimenting. It is worth mentioning that I took a bad first step by trying to edit my .cshrc first. I could not quite get the backslash escaping to work correctly, not being sure when the escaping was taking place: when reading the .cshrc file or when running the alias. After a few minutes of frustration, I tried defining the alias first, character by character, in a cycle:

a) add a new character to the alias
b) echo the current alias by enter 'alias T' to verify the csh interpretation
c) add backslashes as needed
d) verify again.

This worked and I got my alias to work in a minute or two. Once the aliases were working, I just copied and pasted them into my .cshrc file and the aliases both worked. My working aliases are:

alias T echo -ne \"\033]30\;\$Z\007\"

and

alias DT echo -ne \"\033]30\;\%d\ \$Z\007\"

Note that I had to use the environment variable 'Z' to make the aliases 'variable'. Not too elegant, but it largely satisfies me. So after changing my .cshrc and sourcing the .cshrc file in the window shell, I do this

    set Z=Example
    T

or

    set Z=Example2
    DT

and I get my title set. When I change to a different task, I change Z to a new name and run my alias 'T' or 'DT' again.
