Hi,

Often, I run commands like

and the list of files looks like

hey1
hey2

If you know in advance that you're going to want to do this, invoke
fc *first*, then run the "find" or whatever from inside your editor to
capture the output, and edit it into commands as you will.

You can even do this afterwards if you're willing to wait for the "find"
to run again.

Or you can do this:

    FINDOUT=/usr/tmp/find.$$
    find() {
	command find $* | tee $FINDOUT
    }

Then every time you run "find" the output gets captured for you, and you
can "vi $FINDOUT" or whatever to edit it into commands.

If you don't anticipate running finds that generate megabytes of output,
you can use:

    find() {
	FIND="$(command find $*)"
	echo "$FIND"
    }

Then "vared FIND" works, etc.

Probably the neatest way (it doesn't require any editors) is

print -z "$(find . -name 'hey' -print)"

(double quotes necessary) which sticks the output straight into the
multi-line buffer, so you can edit the list and the whole lot will be
executed when you hit return.

If you need an external editor, it doesn't look like fc will help from
reading the manual page --- it doesn't seem to interact directly
either with the line editor or even with standard input: something
like you're original thought is probably necessary.

how to get standard output used in command line editor?

[Jose Unpingco]

Hi,

Often, I run commands like

find . -name 'hey' -print

and I get a list of files I'd like to apply various commands to.

Is there a way to use fc to edit the list generated by the find command
and then use the newly edited list as a command?

the only other way I can figure it is to send the find output to a file
and then source it after editing.

thanks.
