RE: Obtaining short DOS file names?

[Barry Buchbinder <BBUCHBINDER at niaid dot nih dot gov>]

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.

I've attached a Perl script that converts long file names to short file
names. Hope that some else finds this useful.

milhouse% perl shorten.pl  '/cygdrive/c/Program Files/Microsoft Visual \
Studio/VIntDev98/ScriptLibrary/RECORDSET.HTM'
