I have a working command which I would like to make an alias for, but can't seem to figure out how to do. The working command is
docker-compose logs -f | less -S -R +F
This works fine, essentially removing word wrap from the logs.
The caveat is that when using this I also want to be able to optionally add arguments to the middle, to specify the particular service(s) to tail. Making something that end up looking like this
docker-compose logs -f service1 service2 etc... | less -S -R +F
To be able to do this I was thinking I could use xargs -I to pass in a variable number of arguments and inject them into the middle of the command. But my skill with bash is very limited, and so no matter how much I fiddle with it I can't seem to get it to work, and am sure there is something/some concept I'm missing.
The last iteration of the alias I tried before posting this is
alias logsx="xargs -I{} bash -c 'docker-compose logs -f \"{}\" | less -S -R +F'"
which when you run it seems to start less but without the docker logs being piped there.
Any help would be greatly appreciated. Thanks!
All you need is a function instead.
logsx() {
docker-compose logs -f "$@" | less -S -R +F
}
"$@" will expand the arguments given. So you write logsx service1 service2.
