I don't understand it :(.
-r, --no-run-if-empty if there are no arguments, then do not run COMMAND;
if this option is not given, COMMAND will be
run at least once
Can you give some examples?
Sure, thanks for the quick response.
I have this command: $(docker ps -aq --no-trunc --filter name=^/"
I pipe it to xargs -r docker container rm
and use it inside a CI/CD pipeline, so it can delete the specified containers.
With GNU xargs -r, if the specified container doesn't exist, then it does nothing and exits with an error code of 0, which is what I want.
But I can't seem to find the equivalent in rush, I don't even know if this feature exist, so I wanted to know.
Another example could be: docker images -f dangling=true -q | xargs -r docker rmi
Not supported, but there's a workaround solution.
docker images -f dangling=true -q | rush 'docker rmi || true'
Oh well, never mind then.
Another question... Do you think this feature is out-of-scope for rush? If it can be added, I would be very glad to contribute to rush and make a PR if you like!
I'm not sure if this feature is widely used, but since it depends on a GNU extension, if it's implemented in this project simply and elegantly, it could be a step forward for rush to be used by users who rely on GNU xargs like me.
Sure PR is welcome. To be honest, this project gets complex for me. Some low-level (process and signal) operations contributed by @bburgin are hard to understand for me :( So I might I may not be able to help.
Personally, I rarely use that feature.
Alright, the idea would be to implement the feature as simple as possible, and if its not feasible that way, then I would just leave it as it is.
Hi! Pretty much the title. As the repository doesn't have a Discussions page, I'm asking here.
As I want to replace my utils with Go equivalents, I want to replace xargs with rush but I can't seem to find the equivalent option. -c for continue doesn't seem like it, besides the fact that it creates a file, which is something I don't want.
Thanks in advance!
