许多参数传递给Rails中的脚本

Question

I successfully passed one parameter to bash script in Rails:

par = @repository.repo_name
@result = %x[script/delete_repo.sh #{par}]

Now i need to pass 2 parameters into different script. This solution doesn't work:

par1 = params[:repository][:repo_name1]
par2 = params[:repository][:repo_name2]
@result = %x[script/rename_repo.sh #{par1} #{par2}]

The script i want to use is:

#!/bin/sh
mv repositories/$1 repositories/$2

How to send more parameters to stored bash scripts in Rails ?

Answer 1

par1 = params[:repository][:repo_name1]
par2 = params[:repository][:repo_name2]
@result = %x[script/rename_repo.sh #{par1} #{par2}]

If par1 or par2 can have embedded blanks you should embed them inside double or single quotes:

@result = %x[script/rename_repo.sh "#{par1}" "#{par2}"]

or:

@result = %x[script/rename_repo.sh '#{par1}' '#{par2}']

But, instead of creating a subshell, which happens when you use %x or backticks, use FileUtils built-in ability to mv files:

require 'fileutils'
@result = FileUtils.mv(par1, par2)

Answer 2

I don't know about %x. but

`sh script/delete_repo.sh #{par1} #{par2}`

should work.
