Oleg/other forum members:
Is there any way to use spawn_jtask_ to "talk to" Cygwin's bash shell? I
thought that
shell_script =: noun define
some shell commands
like, for example, ls
or cat
)
require 'task'
output =: shell_script spawn 'C:\cygwin\bin\bash.exe'
would work, but it does not. The bash commands are being interpreted as if
they're running under cmd.exe.
For example, I have two versions of wget: one compiled for Windows, one for
Cygwin. The Windows one is slightly older and doesn't support the
"--save-cookies" option. So, in cmd.exe, this happens:
wget --save-cookies URL
wget: unrecognized option `--save-cookies'
but the same command executes fine under bash.exe.
My problem is when I try to spawn a bash from J, I get the cmd.exe behavior,
not the bash.exe behavior:
require 'task'
('wget --save-cookies URL',LF) spawn 'C:\cygwin\bin\bash.exe'
wget: unrecognized option `--save-cookies'
For various complicated reasons, I cannot write my shell script to a file, the
entire thing has to be a J noun passed as stdin to bash.exe. Am I out of luck?

PS: I recommend that spawn be modified to optionally take a "working
directory" for the process. I have made this modification in my local copy.
