Gotcha. I can hack something up from this.

It would, but it will take me a while to track down all of the places that
the scripts are broken. I'm looking for something quick and dirty to get
going.

Ok, this version works. It's faster than my script, but my version shortens
the entire full file name.

RE: Obtaining short DOS file names?

[Barry Buchbinder]

The output of dir is different in command.com and cmd.exe.  In a version I
have of cmd.exe compiled for win9x, the following works for me.

function sfn() {
  win95cmd /c dir /x "$1" | \
    sed -e '/^ /d' \
      -e 's/^......................................//' \
      -e 's/^ *//' -e 's/ .*//'
  }

You might have to play with the options to dir and with the sed processing
to get it to work for Win2k.

This doesn't work under Win2k. First, it doesn't like "command.com". After
changing that to "cmd", it just prints the date when the first was
modified...

RE: Obtaining short DOS file names?

[Barry Buchbinder]

This works on Win98.

Try putting this function in .bashrc

function sfn() {
	command.com /c dir "$1" | sed -e '/^ /d' -e 's/^............/&^G/'
-e 's/^G.*$//' -e 's/ *$//' -e 's/  */\./'
	}

(Note: "^G" is a control-G/bell, which I don't expect to find in a DOS
filename.)

Then if you just want a list, you can do the following
	$ sfn dos_file_spec
If you want to feed the list to a program, do
	$ prog `sfn dos_file_spec`
Remember to quote or escape anything that bash might expand.

Command.com must have the ".com" typed.  I'm not sure that it will work or
can be easily adapted for cmd.exe.  sfn takes a single argument.

It's ugly and slow, but it works for me.  Excuse me if my sed programming
was less than elegant.

There is no cygwin-specific way of getting the short file name.  The concept
has no meaning on UNIX.  There are Windows programs available which do this.
'dir' is one of them, for instance.

Is there some reason why quoting the filename doesn't work?

Obtaining short DOS file names?

[Paul Stodghill]

I'm working with some shell scripts under Cygwin that do not handle spaces
in file names very well. "No problem," I think, "I'll just use the short
versions of the file names".

Is there anyway to obtain the short version of a file name from the long
version within a shell script?

E.g.,

		c:\Program Files\Microsoft Visual Studio\ ->
			c:\PROGRA~1\MICROS~4\
	or
		/cygdrive/c/Program Files/Microsoft Visual Studio/ ->
			/cygdrive/c/PROGRA~1/MICROS~4/

Thanks.
