How to write a batch file for windows that starts cygwin tool and runs unix scripts


I need to write a batch file for windows that automatically starts the cygwin tool in windows and executes the unix scripts.Previously we had these scripts in unix server.Now we need to migrate them to Windows server.For this reason we are using cygwin tool that allows the scripts to be executed on Windows server.We had written a batch file that starts the cygwin tool,but we were not able to execute the unix scripts.How can we write a batch file such that it executes all the unix scripts in cygwin.

IMHO, that won't work. cygwin operates almost like a virtual machine inside windows. DOS or CMD interprets command line interface in Windows, and interprets batch files the same way.

I'm no cygwin buff, but maybe if you setup a script to bootstrap your other scripts after cygwin starts? Look at this link for more information, right down the bottom of the page is something like this:

Edit the main startup script, /Cygwin.bat, (which is c:\cygwin\Cygwin.bat). If you use nano from within the cygwin shell, type: (etc etc....)
Can you call your scripts from within Cygwin.bat? Be careful here, i'm not sure of the consequences. A reminder from another member here:

Before you do anything I tell you to, I presume you have a working verifiable backup!

We were able to call the other scripts from within the cygwin tool just by manually running each script.(./
However we need this to be done automatically(at scheduled times)
For Ex : if we need to run a script called on every Monday morning at 4.30AM we need to schedule this script in such a way that every Monday morning 4.30AM cygwin tool should be started and the script should be executed from within the cygwin tool automatically.Can we do this ?
Thanks in advance.

On this thread:

I answered your question a few years ago.

The essential detail is that you can execute a cygwin script within a DOS batch file like this:

start c:\cygwin\bin\bash.exe -l myscript

I tried to perform this

C:\cygwin\bin>c:\cygwin\bin\bash.exe -l <script>

But I get this response:

Your group name is currently "mkgroup_l_d". This indicat
all domain users and groups are listed in the /etc/passw
/etc/group files.
See the man pages for mkpasswd and mkgroup then, for exa
mkpasswd -l -d > /etc/passwd
mkgroup -l -d > /etc/group

This message is only displayed once (unless you recreate
and can be safely ignored.
cp: `Settings/<user_account>/group.mkgroup_l_d': specified
Try `cp --help' for more information.
cat: XXXXXXlog: No such file or directory

in the scritps (1st line) it needs to perfrom a cat of a log file (which resides in the same folder (C:\cygwin\bin)

When i just run the bash file and try to run a cat from there it shows me this:

bash-2.05b$ <script>
bash: available_tapes: command not found

Someone any idea ? I just want to run a Windows scheduled task that launches a unix script with Cygwin.
