Hi,
I ran into some trouble when I wanted to construct a command based on
the contents of a file. For the sake of the argument, let us say I have
> cat >file
junk
cmd: echo -e foo\nbar
trash
and I want to run the part after ‘cmd:’ as a command. How do you do
this in fish?
To elaborate, in bash I could do something like this
$ $(grep file -e cmd: | cut -d: -f2)
foo
bar
but fish does not let me use ‘(…)’ as a command:
> (grep file -e cmd: | cut -d: -f2)
fish: Illegal command name “(grep file -e cmd: | cut -d: -f2)”
I also tried putting the command in by hand, and only getting the
arguments from the external command, but that does not work either:
> echo (grep file -e cmd: | cut -d' ' -f3-)
-e foo\nbar
apparently because ‘(…)’ is interpreted as a single word.
I am using fish 2.0.0.
