Automatically capture output of last command into a variable using Bash?

Question

I'd like to be able to use the result of the last executed command in a subsequent command. For example,

$ find . -name foo.txt ./home/user/some/directory/foo.txt 

Now let's say I want to be able to open the file in an editor, or delete it, or do something else with it, e.g.

mv <some-variable-that-contains-the-result> /some/new/location 

How can I do it? Maybe using some bash variable?

Update:

To clarify, I don't want to assign things manually. What I'm after is something like built-in bash variables, e.g.

ls /tmp cd $_ 

$_ holds the last argument of the previous command. I want something similar, but with the output of the last command.

Final update:

Seth's answer has worked quite well. Couple of things to bear in mind:

• don't forget to touch /tmp/x when trying the solution for the very first time
• the result will only be stored if last command's exit code was successful

Answer 1

I don't know of any variable that does this automatically. To do something aside from just copy-pasting the result, you can re-run whatever you just did, eg

vim $(!!) 

Where !! is history expansion meaning 'the previous command'.

If you expect there to be a single filename with spaces or other characters in it that might prevent proper argument parsing, quote the result (vim "$(!!)"). Leaving it unquoted will allow multiple files to be opened at once as long as they don't include spaces or other shell parsing tokens.
