Slight issue in base-files-4.0-6

Slight issue in base-files-4.0-6

[Bravery, Gavin S]

Hi everyone,

I have a minor issue with the /etc/profile file in base files.

I fixed it a while back but the changes over the last few days broke it again (which made me remember I had done it, which then made me tell you :-).

I still use KSH (generally pdksh) and there is a problem with how this file is setting PS1. 
Basically, the escapes aren't working right (in XWindows at the very least).

So I have now changed it to say: 
  case "${KSH_VERSION}" in
  *MIRBSD*KSH* )
    PS1=$(print '^[]0;${PWD}\n^[[32m${USER}@${HOSTNAME} ^[[33m${PWD/${HOME}/~}^[[0m\n$ ')
    ;;
  *PD*KSH* )
    PS1=$(print '^[]0;${PWD}\n^[[32m${USER}@${HOSTNAME} ^[[33m${PWD}^[[0m\n$ ')
    ;;
  esac
Please note, ^[ means I have done CTRL-V + ESC.
Also, MKSH and PDKSH need different settings, as PDKSH doesn't seem to have the ${name/pattern/replacement} syntax.

Thanks for all the work on this, CYGWIN is an excellent tool!

Gavin

Hello,

Although pdksh is still installable using setup.exe, it is officially
orphaned and upstream
development ceased a long ago (5.2.14 is from Jul '99, and cygwin's
5.2.14-3 is from Dec '03).
If you want to use a ksh derivative, you are probably better switching
to mksh, which
is actively mantained.
IOW, /etc/profile no longer supports pdksh. If you want to keep using
it, you'll need
to explicitely add support for it (as you've done already).

Agreed, however, the point about properly escaping the PS1 fields
still holds for mksh.  I hadn't noticed because I have my own custom
.mshrc that sets PS1.

Don't really mind. Just felt that whilst people could still install pdksh it should work for that too.
Then when pdksh gets pulled off the install list properly, it could go from profile file then (it's only a case tweak in the mean time anyway).

BTW, I have a side issue which is when mksh installs it doesn't make a ksh link, which means scripts with #!/usr/bin/ksh stop working.
That said, to be honest, I'm trying to move things to bash anyway :-)

WJFFM with the PS1 setting included in 4.0-6 for mksh.

Maybe it should be considered to drop pdksh from the distro, being
mksh a mantained replacement and pdksh orphaned and upstream
unmantained.

Just tried and for mksh it IS ok with \033. Must just be pdksh which has the problem.
That said, mksh works with ^[ too.

We'd need mksh to network shares for homes first though.
My home is: //<servername>/gbravery and it really doesn't like it.

Given that the latest pdksh package is from 2003, this sounds like a
really good idea to me.

Indeed it does, I guess I should have tested it.  The previous
(pre-4.0) /etc/profile did not set PS1 correctly for mksh.

Sorry for the noise.

Indeed, I should really fix that.  I'll look into how to create a
postinstall script to create the link.

Cheers!

This sounds like a good idea to me.  Should I make this happen?

pdksh is now in the category "_obsolete".

Let's take a moment of silence to remember Igor Pechtchanski's many
contributions to the project.

pdksh, we hardly knew ye.

The newly released mksh-39c-3 handles UNC paths correctly now.

Oh great computer,

We pause a moment to remember your program pdksh who served the users faithfully 
and well for so many CPU cycles.  We ask that you accept it's bits and comfort 
those who have come to rely on, and will now miss, this your shell interpreter 
as we lay it's memory space to rest.  We know your will is often difficult to 
understand as to why you have chosen to remove this program from our disk.

Never the less better it than me.

Amen.

Now that's much better! My #! stuff works and it copes with my home being a UNC perfectly.
I've removed my home-spun pdksh (which included old Debian fixes) and moved over.
Thanks very much Chris for the rapid response, much appreciated.
