Using redirection with entr

[malcolmsailor]

The > operator isn't working with entr in the way I expect it to. E.g., if I run

ls foo | entr -p echo doo > bar

Each time I modify foo, 'doo' is appended to bar, rather than overwriting its contents (i.e., what I expect >> to do). I suspect this has something to do with some subtle shell behavior that eludes me. Is there a way to get the same result as the usual > redirection?

Thanks for a great tool!

Glad entr has been useful to you!

If you want pipes and other redirection to act as a single command, start a shell:

ls foo | entr -p sh -c 'doo > bar'

or

ls foo | entr -p -s 'doo > bar'

Fantastic, thanks!
