Re: Direct/efficient way to chop off trailing \n
You're welcome, Paul. But I see some streamlining that could be done
since I wrote that xx() alias long ago. I do like Barry's "cygpath
-aw foo/bar | putclip -d" as it likely runs faster.

Thanks, Keith. I think it will be educational for me just to figure

Which I find odd. If you like bash, then that's going to be your
explorer, and I am *never* able to work exclusively in cygwin.
I suppose you can always use cygstart to launch app files
or executables, but Windows can be very inconsistent at times. I
never know when cygstart will launch a new instance of an
already-running app. Also, I often encounter the need to specify a
file location but not emulate a double-click on that file.

Yeah, I suppose that was a circular truth. I should have said that
outside of cygwin, few people need to operate in both the POSIX and
Windows world at the same time. I guess those cases would be the ones
in which cygpath is used, and those are also the cases in which it
would be handy to have \n chopping capability built in to cygpath.

I don't care about the computational speed, I probably won't notice

I will give you code idiom a try. Thanks.

Gary, I was hoping for a magic bullet code idiom so that I don't have
to haul around a growing .alias.bash file. But I think your solution
might be the only one that significantly cuts down on the typing.
Jim, I think you're right. cygpath could benefit a lot from a -n
switch to suppress the new line. From google, however, it's actually
just li'l olde me that would benefit as no one else seems to have the
want for it. So I can see why such a switch has never been developed.
It's probably only needed for cygwin users, as it is the *unixy crowd
that uses both Windows & *nix at the same time.
Eliot, your solution takes 2 characters less than mine. If I want to
live without spaces aroud the "$(" and the ")". Which I suppose I
could do, for 2 characters. I'm a bit enamoured of the linear
simplicity of my original pipeline, though. Appreciate the other
perspective, though.
Thank you all.

The trouble with that is that the "problem" is common to (almost?) all Unix commands, not just cygpath. That is, they all send their output to stdout as lines of text, each line terminated by a newline, as it should be. You can send the output of any command to /dev/clipboard and it will be terminated by a newline. If that's not desired, then one needs to take extra steps in the pipeline, which is what tr is for. Another solution would be to wrap the redirection to /dev/clipboard in a function or script that takes your "-n" option and pipe the output of cygpath or whatever command to that wrapper.

Re: Direct/efficient way to chop off trailing \n
Looks like the cygpath line was broken in two, and the closing brace
isn't visibile when reading in Gmail.
Readers take note of that.

Re: Direct/efficient way to chop off trailing \n
This function echoes the present directory to the clipboard, so that I
don't have to enter the path manually.
I use this function in a script that sources when a bash shell is
started. Also echoes the path to the terminal for verification.
Handy for pasting directly into windows file dialogs.
function xx() {
DESCRIPTION="Copy the Windows drive/path/filename to the clipboard"
cygpath -w "`pwd`"|tr -d "\012"|sed -e

Define a function in your ~/.bashrc.
winclip()
{
cygpath -aw "$@" | tr -d '\n' > /dev/clipboard
}
Then just execute
winclip TheFile
