Writing script for mac (scp alias with default params)

Question

I have got to write this lines often:

# from project1 dir
scp app/models/user.rb root@mydomain.com:/var/www/project1/app/models
# from project2 dir
scp app/views/posts/index.html.erb root@mydomain.com:/var/www/project2/app/views/posts
scp -r app/mailers root@mydomain.com:/var/www/project2/app/

so I want to wrap it as a script

scpd project1 app/models/user.rb
scpd project2 app/views/posts/index.html.erb
scpd project2 -r app/mailers

so scpd will pass all options to scp and take first argument as a dirname on server's /var/www/ path.

So the question is: what is a common way for writing terminal scripts on macos? And some links to read about it. Bash? And maybe I can write it on Ruby? :)

Answer 1

Any of these work. Bash, ruby, python, perl, they all come with the system. Do it any way you know how.

Answer 2

Here's a bash function for you:

scpd () {
    # the first argument is the project
    # the last argument is the file/dir to send
    # any arguments in the middle are scp options

    args=( "$@" )

    proj="${args[0]}"
    file="${args[@]: -1}"
    scp_args=( "${args[@]): 1: $(( ${#args[@]} - 2 ))}" )
    remote_dir="${file%/*}"

    scp "${scp_args[@]}" "$file" "root@mydomain.com:/var/www/$proj/$remote_dir"
}

You can paste it into your ~/.bashrc
