Ruby Simple Read/Write File (Copy File) -

-

i practicing ruby, , trying copy contents file "from" file "to". can tell me did wrong?

thanks !

from = "1.txt" = "2.txt" data = open(from).read out = open(to, 'w') out.write(data) out.close data.close

maybe missing point, think writing more 'ruby'

from = "1.txt" = "2.txt" contents = file.open(from, 'r').read file.open(to, 'w').write(contents)

personally, however, use operating systems terminal file operations so. here example on linux.

from = "1.txt" = "2.txt" system("cp #{from} #{to}")

and windows believe use..

from = "1.txt" = "2.txt" system("copy #{from} #{to}")

finally, if needing output of command sort of logging or other reason, use backticks.

#a nice 1 liner `cp 1.txt 2.txt`

here system , backtick methods documentation. http://ruby-doc.org/core-1.9.3/kernel.html
