shell - How do I merge all the cases into One -


how can merge following 2 case scripts?

script 1

#!/bin/bash ver=0 n="192.168.1.20:/backup/b1" o1="192.168.1.20:/backup/b2"     user="1234" echo "n latrest version"     echo "o1 previous version n-1" echo "o2 previous version n-2" echo -n "which version want backup [n or p]? " read ver     case "$ver" in     (n|o1|o2) scp $user@${!n} . ;;     (*) echo "unknown user"     esac

above script not working error

cannot stat `1234@': no such file or directory

script 2

user=0     av="34567"     ma="4568"     im="5678"     mi="12345"     pr="23456"     echo "please select av ma ji im pr"     echo -n "first 2 initial of name eg: [av ma ji im pr]? "     read user     case "$user" in     (av|ma|pr|mi|im) scp ${!user}@$n . ;;     (*) echo "unknown user"     esac

bit of mix between variables $n , $ver, , value of $o2 not specified.

#!/bin/bash echo "want download [yes no]? " read response [ "$response" = "yes" ] || exit  n="192.168.1.20:/backup/b1" o1="192.168.1.20:/backup/b2" o2="192.168.1.20:/backup/b3" echo "n latest version" echo "o1 previous version n-1" echo "o2 previous version n-2" echo -n "which version want backup [n o1 o2]? " read opt case "$opt" in     n|o1|o2)         server="${!opt}"         ;;     *)         echo "invalid option" >&2         exit 1         ;; esac  av="34567" ma="4568" im="5678" mi="12345" pr="23456" echo -n "enter initials [av ma im mi pr]: " read opt case "$opt" in     av|ma|im|mi|pr)         user="${!opt}"         ;;     *)         echo "unknown user" >&2         exit 1         ;; esac  scp "${user}@${server}" .

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
