Could Strawberry Perl be messing up bindkey settings on tcsh?

Just in has asked for the wisdom of the Perl Monks concerning the following question:

Rather off topic, and rather insinuating, but googling has run off at tangents so I do beg your pardon. However someone may have some insight . . .

I've downloaded and installed Strawberry Perl 5.8.8.4 on two Vista boxes both to C:\strawberry, both have tcsh courtesy of cygwin in C:\bin, and both have AS 5.10 in C:\Perl which I manage by editing %Path% as and when I please.

It seems that after the Strawberry install the up key no longer shows the last command in tcsh, instead the cursor goes up a line. In fact all the keybindings are being ignored, and all I'm getting is "^[[A: Command not found."

source /etc/profile.d/bindkey.tcsh

has no effect, and neither does uninstalling Strawberry.

I was able to use Windows restore to get tcsh to behave so it's not as dire as all that, but was wondering if any of you have any ideas/pointers that I could try?

cygwin version follows:

$ uname -a
CYGWIN_NT-6.0 mimi-PC 1.7.7(0.230/5/3) 2010-08-31 09:58 i686 Cygwin
[download]

Something else changed. Strawberry Perl does not really adjust anything. Maybe you can try reinstalling Strawberry Perl now to see if the problem is directly connected to it?	[reply]

It's quite definite - I've done a system restore, got the up key to work in tcsh as expected. Just to make sure it's not a 5.8 thing, I downloaded 5.12.0.1.msi and installed it to C:\strawberry Fresh after the install, no reboot needed, I launched tcsh and after pressing the up key I get the dreaded '^[[A: Command not found." Unlikely as it seems, what could be the cause? I'll repeat the process tomorrow and do text registry snapshots before, but I doubt anything will be evident from the diff. Just in	[reply]

If you've moved `tcsh` from `C:\cygwin\bin` to `C:\bin`, then that may be where your problem lies. Under Cygwin, `C:\bin` is actually `/cygdrive/c/bin` which is different from `/bin` (where `tcsh` lives). Further, you say you've edited `%Path%` (which is fine for the MSWindows environment) but do you also need to edit `$PATH` (for the Cygwin environment). Two other gotchas (related to Cygwin symlinks): What you see under Cygwin as `tcsh`, is actually `tcsh.exe` `C:\cygwin\usr\bin` probably looks empty; however `which tcsh` from Cygwin, probably shows `/usr/bin/tcsh` Additional Info: I have the same Strawberry Perl as you indicate installing (5.12.0.1 MSI) but I'm using XP not Vista. Neither MSWindows nor Strawberry Perl know anything about `tcsh`: Microsoft Windows XP [Version 5.1.2600] (C) Copyright 1985-2001 Microsoft Corp.

Here I launch `tcsh` (from the `bash` shell), run `which tcsh` then hit up-arrow to get the last command: `ken@Miranda ~ $ tcsh [ken@Miranda ~]$ which tcsh /usr/bin/tcsh [ken@Miranda ~]$ which tcsh` [download] And just for completeness, the `bash` shell finds `tcsh` in the same place: `ken@Miranda ~/c/_/tmp $ which tcsh /usr/bin/tcsh` [download] -- Ken	[reply] [d/l] [select]

Strawberry Perl installer will set the environment variable TERM to dumb I have amended my cygwin.bat launcher thing to have: `set TERM=cygwin` [download]	[reply] [d/l]

My MSWindows TERM remains dumb; my Cygwin TERM is xterm: `C:\_\tmp>echo %TERM% dumb C:\_\tmp> ken@Miranda ~ $ echo $TERM xterm ken@Miranda ~` [download] -- Ken	[reply] [d/l]
