i installed a Cygwin ( https://www.cygwin.com/ ) in my windows server and now I can execute bash script in windows. I want to write script that implement bash script in my powershell script.
When I start this command in powershell

I see that it's a few command that are not recognize from powershell - rm et.c. When i start the script in cygwin terminal, i can execute without problem. I send too the bash script:

!/bin/bash  
# define general stuff  
host=.  
certdir=/cygdrive/l/$host.  
certdir_local=L:/$host..  
outcert_cygwin=/cygdrive/c/certbot  
storepass=.  
  # rm old pfx file  
  rm $outcert_cygwin/letsencrypt.pfx  
  # convert the cert to some tomcat shizzle  
  openssl.exe pkcs12 -export -out $outcert_cygwin/letsencrypt.pfx -inkey $certdir/privkey.pem -in $certdir/cert.pem -certfile $certdir/chain.pem -password pass:$storepass  
  # change permission of the cert  
  chmod 644 $outcert_cygwin/letsencrypt.pfx  
  # additional info, for server.xml  
  echo "Make sure the contents of c:\certbot\tomcat_server_config.txt are"  
  echo "added to the tomcats server.xml"  
  echo "Exiting."  
  exit 0  
# else  
#   echo "Exiting."  
#   exit 0  
# exit 0  
Can anybody help me how this command would be recognized from powershell? For example the command rm is available. See you screenshot:

Try this:  
Open Window's File Explorer. Find a file that uses the ".sh" extension. Right-click it and select "Open with". Select "sh.exe" and "Always use...".   
Assuming that your PATH variable points to when you have Cygwin installed you should be able to run your shell scripts without running bash.
