I am totally reliant on my bash aliases and readline configuration. When working
on a new server, the first thing I do is copy over my local Bash (~/.bashrc)
and Readline (~/.inputrc) configuration files.
One mildly annoying issue is when you update a config file, it’s a pain to copy
it onto all your remote hosts. To scratch this itch, I wrote a simple node.js
executable for copying a file to all the defined hosts in your ~/.ssh/config
file
Usage is trivial:
$ multi-scp ~/.bashrc
Starting sync of '~/.bashrc' to all hosts in /home/david/.ssh/config
-> Copying to mars
-> Copying to venus
-> Copying to jupiter
<- Successful copy to mars
<- Successful copy to venus
<- Successful copy to jupiter
Using node.js seems an odd choice as this could trivially be done in another scripting language. However, I wanted to use node as:
- it allows the copy operation to run asynchronously in a child process with a callback to handle completion and error;
- it’s fashionable.
The code is on Github as usual.
