Re: using aliases for cygwin commands on win2k

[Jean-Marc Eurin <jmeurin at yahoo dot com>]

Hello,

Here are a couple of bash functions that I use to open
files from cygwin. The first function is what I found
on the web a while back, the second one is my
customization.

You can then do things like:
of foo.doc ../bar.xls 

Jean-Marc 

#-*-shell-script-*-
# open any file in the correct program: an associated
file-type (see assoc
# and ftype at Windows NT/2000) will be opened with
the associated program.
# Not associated filetypes and files which extension
is contained in
# $PATHEXT will be opened in the texteditor (here
Emacs). Files with
# extension .exe and .com will not be opened!

function open-file-with-w32 ()
{
	for i in $*; do
		if [ -f "$i" ]; then
			# get the extension only
			erg=`echo $i | sed -e 's|.*.||g;'`
			# check if we try to open a program
            if [ "$erg" != "exe" ] &&
               [ "$erg" != "EXE" ] &&
               [ "$erg" != "com" ] &&
               [ "$erg" != "COM" ]; then
                # check if we try to open a file with
a extension from $PATHEXT
                is_path_ext=`echo "$PATHEXT"; | grep
-i ".$erg;"`
                if [ "$is_path_ext" == "" ]; then
                    # check if this extension is
associated with a w32-program
                    erg=`cmd /x /c assoc ".$erg"
2>/dev/null`
                    if [ "$erg" != "" ]; then
                        # an association exists
therefore this call should
                        # theoretically not produce an
error.
                        cmd /x /c start /b `cygpath -w
"$i"` 2>/dev/null
                    else
                        # we must open the file with a
text editor because
                        # it is not associated.
                        gnuclient -q `cygpath -w "$i"`
                    fi
                else
                    # files with a extension contained
in $PATHEXT will be
                    # opened with the text editor.
                    gnuclient -q `cygpath -w "$i"`    
       
                fi
            else
                echo "$i is a program!"
            fi
        fi
    done
    unset erg is_path_ext;
}
