Run bash script in cmd with cygwin

Run bash script in cmd with cygwin

[Ulrich Pogson]

Hello

I would like to run this script `for file in `find . -name "*.po"` ;
do msgfmt -o ${file/.po/.mo} $file ; done` in windows cmd. The script
need to run in a different folder. I have been able to run it though
cygwin but want to integrate it with another system where it will be
run through cmd.

C:\cygwin\bin
D:\path\to\dir

How can I do this?

Thanks.

Try adding this to your script:

cd /cygdrive/d/path/to/dir;`for file..

Thanks Matt, after try everything I could not get it to work. Could
you give me the whole code that I could enter in cmd that would run
cygwin and then run the script?

If my other post to this thread doesn't help, post the errors you get. 
You're making us guess what is wrong with "everything", and we don't 
know what's wrong with "everything". :)

What exactly do you mean by "in windows cmd"?

If you're trying to translate this script into cmd.exe's "batch" 
language, it's not going to be an easy translation because batch is 
about as impoverished as programming languages get, and you're using 
some pretty advanced Bash features here.  Pattern substitution in 
variable interpolation and command output substitution don't even exist 
in cmd.exe's batch language.  You'd have to fake it with temporary files 
or some other hack like that.

If you're just trying to get this bit of Bash code to run from cmd.exe 
but you can still have Bash installed, the solution is fairly simple:

     d:\path\to\dir> bash -c "for file in..."

The trickiest part is handling all the quoting, so it gets to bash.exe 
correctly.  It might be simpler to put this into a script file so you 
can say "bash -c /path/to/my/script.sh" instead of depending on cmd.exe 
to get quoting right.

You also have to handle the PATH issues.

The simplest option is to make sure the Cygwin bin directory is at the 
start of the PATH while in cmd.exe.

If you can't do that, then you end up with something fairly ugly:

    c:\> c:\cygwin\bin\bash -c "for file in `/bin/find..."

Note that you have to give explicit path names in both DOS and POSIX 
forms here for the different parts.  You have a special trap here 
because Windows provides a find.exe, and it isn't at all the same thing 
as Cygwin's find.exe.

I think you mean "command line" and not a "script".
This is not realistically possible. Windows CMD do not have as straightforward
quoting and escaping rules, as you might wish for it to have.
Your only safe bet is to actually write a script and execute it from cmd, when
need.

The association:

FTYPE unixshell.script="%CygwinDir%\bin\env.exe" "%1" %*
ASSOC .sh=unixshell.script

then your find-poo.sh

#! /bin/sh
for file in $(find . -name "*.po")
  do msgfmt -o ${file/.po/.mo} $file
done

Thanks for your help

I got it to work with this line.
I: & cd I:\Work\GitHub\responsive\languages & c:\cygwin64\bin\bash -c
\cygdrive\i\Work\GitHub\responsive\languages\potomo.sh
and this file.

Hi Andrey,

I am sorry I don't fully understand. I am a beginner try to get
something to work. What I am doing is that after pulling the .po I
need to create a .mo file.

   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Cygwin prefers POSIX paths and separators.  You should prefer / over \
for this final path.
