Cygwin: Command works on the console, not in a .bat

Question

This command works in the Cygwin console:

me@WDX5CG625Q ~
$ cd "/cygdrive/c/Program Files/apache Software Foundation/Tomcat 8.5"

mw@WDX5CG62Q /cygdrive/c/Program Files/apache Software Foundation/Tomcat 8.5
$

But not in a .bat file:

tom.bat:

cd "/cygdrive/c/Program Files/Apache Software Foundation/Tomcat 8.5"

output:

me@WDX5CG625Q ~
$ ./tom.bat

C:\cygwin64\home\me>cd "/cygdrive/c/Program Files/Apache Software Foundation/Tomcat 8.5"
The system cannot find the path specified.

me@WDX5CG625Q ~
$

Also tried:

• With a #!/bin/bash
• Without quotes
• Without quotes and spaces escaped
• With quotes and spaces escaped

Always get the “cannot find” message.

Answer 1

When you run a .BAT file from Cygwin, it runs as a batch file, using the Windows command interpreter (CMD.EXE, a.k.a. “Command Prompt”).  So

• If you want to run a batch file, using primarily Windows CLI commands, use the Windows version of the pathname: C:\Program Files\apache Software Foundation\Tomcat 8.5.  It’s probably OK if you use / instead of \, just as it is in an ordinary Windows Command Prompt.  Don’t worry about case.
• If you want to run a Unix shell script, don’t use the .BAT extension.
