ResolveCommand results in FATAL error

[edi-design]

Hey,

I tried this now for almost two hours and I am sorry, but I can't find any solution for this.
I have a lot of hosts under one domain and i'd like to not type the full hostname everytime i would like to connect.

I tried to solve this by using the ResolveCommand.

My config:

hosts:

  "*.fresh":
    ResolveCommand: /bin/sh -c "echo $(echo %h | sed s/.fresh//).freshest.me"
    Inherits:
    - private-template


templates:
  # Templates are similar to Hosts, you can inherits from them
  # but you cannot ssh to a template
  work-template:
    User: worker
  private-template:
    User: andre

defaults:
  # Defaults are applied to each hosts
  ControlMaster: auto
  ControlPath: ~/tmp/.ssh/cm/%h-%p-%r.sock
  ControlPersist: yes
  Port: 22
  User: andre
  TCPKeepAlive: yes
  ServerAliveInterval: 10
  ForwardAgent: yes
  IdentityFile: ~/.ssh/id_rsa

includes:
- ~/.ssh/hosts/*.yml

The following error:

Hopefully someone could help me.

Thank you very much.

Best regards,

Hi @edi-design, thank you for reporting,

Your configuration looks good, there is probably a bug when executing commands with double-quotes, I need to give a deeper look

[moul]

It looks like the issue come from the dollar character

ResolveCommand: /bin/sh -c "echo $(echo %h | sed s/.fresh//).freshest.me"
# fatal error

ResolveCommand: /bin/sh -c "echo `echo %h | sed s/.fresh//`.freshest.me"
# resolving

I suggest you to switch to this syntax while I find a better solution

[moul]

I just fixed the issue in #118, if you upgrade to the latest version (brew upgrade assh --HEAD for instance), you will be able to use your favorite syntax :)

[moul]

do not hesitate to reopen the issue if the problem persists

[edi-design]

Thank you very much.
It works now perfectly.

Again, thank you for your very fast fix and help.
