From: Jordan Wilson <jordan.t.wilson <at> gmx.com> To: bug-gnu-emacs <at> gnu.org Subject: 29.1; Eshell on MS-Windows using plink: 'plink' is not recognized as an internal or external command... Date: Sat, 26 Aug 2023 15:11:53 +0100
Hi all,
I've found a bug in Eshell on MS-Windows on 29.1. This is a regression
from 28.2. When connected to a remote machine using putty's "plink",
using any commands on the remote machine (e.g. not built-in to eshell)
prints this error in the eshell buffer (details replaced):
plink -l username -ssh -t example.com " env 'TERM=dumb'
'PROMPT_COMMAND=' 'PS1=#$ ' /bin/sh -i " ** exit || exit
'plink' is not recognised as an internal or external command, operable
program or batch file.
and the following in the minibuffer:
Tramp failed to connect. If this happens repeatedly, try
"M-x tramp-cleanup-this-connection"
An keyboard input after this causes the eshell buffer to be killed, and the
"Tramp failed to connect..." message to also be inserted into the next buffer.
Recipe, starting from "emacs -Q":
1) open eshell
2) connect to a remote host using plink
- cd /plink:username <at> example.com:/home/username/
3) ./test.sh (executable script)
or...
3) *ls
or...
3) (any remote command not built-in into Emacs)
Below is the backtrace produced from this (using
`toggle-debug-on-error') again with details replaced.
Thanks,
Jordan.
