ConEmu build: 161206 x64
OS version: Windows 10 latest Developer Mode Enabled
Used shell version : git-bash, cmd, powershell
Trie to build a automated task step base on the existing Bash Script task was not successful
I did
%ConEmuDrive%\Git\git-cmd.exe --no-cd --command=usr/bin/bash.exe -l -i
cmd.exe -new_console:d:"cd C:\www && npm start"
two tabs, with one bash and another really just regular windows command line
open one bash tab and running the command cd C:\www && npm start in it!

*Also curious, what exactly are the tasks been written in ConEmu? Are they actually multiple different languages?
The -new_console:d: doesn't support cd or any other commands.
I don't understand the question about languages.
@Maximus5 the script, or the command that wrote in task, clearly they are not shell script no? I mean that, I dont really type all that in the command line to get into a directory, like in console I only need to do cd C:\www and in this "task" script I have to write all that command, what language is it?
Did you really read the links I posted?
@Maximus5 I did and in additional, I read https://superuser.com/questions/1104567/how-can-i-find-out-the-command-line-options-for-git-bash-exe and https://stackoverflow.com/questions/19916670/how-to-launch-a-git-bash-window-with-particular-working-directory-using-a-script and they are different than what in the ConEmu instruction. Super confused, I am still not too familiar with different kind of command line languages.
Would you able to instruct me on at minmum, how to define a task that opens a default bash command and execute one more command after it? like cd c:\www && npm start?
Just tried -c, but still not working
%ConEmuDrive%\Git\git-cmd.exe --command=usr/bin/bash.exe -l -i -c " cd C:\www"
cd c:\www && npm start into -new_console:d:"...". ConEmu is not a bash.c:\www is illegal there! You must use /c/www instead.%ProgramFiles%\Git\git-cmd.exe --command=usr/bin/bash.exe -c "cd /c/www; pwd; npm start"
One more link
@adamchenwei do something like this:
> -cur_console:d:C:\code\terminus "%ConEmuDir%\..\Git\git-cmd.exe" --no-cd --command=usr/bin/bash.exe -l -i -c "ls && $SHELL"
-cur_console:s50H:d:C:\code\terminus "%ConEmuDir%\..\Git\git-cmd.exe" --no-cd --command=usr/bin/bash.exe -l -i -c "git status && $SHELL"
Screenshot:

@kdelmonte this final "...&& $SHELL " , was what I was missing.
because git pull would complete , bash.exe would exit and I always got a notification from ConEmu that the command finished in less than 10 seconds and I would never get a command prompt.
Makes sense to add this specific task invokation in GitForWindows as a new subsection "start git for windows, run a command in bash and provide a prompt afterwards"
