Clojure-Control 0.3.0 is out

    Clojure-control is a clojure DSL for system admin and deployment with many remote machines via ssh. 
    
    I am pleased to annoucment that clojure-control 0.3.0 is out.It adds some  powerful features in this release ,includes:

• ssh and scp both have a new option :sudo  to be executed as root on remote machines,for example:
  

  (ssh "/etc/init.d/ssh restart" :sudo true)

• scp has a new  option :mode to change file modes copied from local: 
  

  (scp "start.sh" "/etc/init.d/start.sh" :sudo true :mode 755)

• A  new function "exists?" to test if a file exists on remote machines:  
  

  (if (not (exists? (str "/home/deploy/.ssh"))) (ssh (sudo (str "mkdir -p /home/deploy/.ssh"))))

• Call other task in deftask with "call" function:

  (deftask :ps "A task to grep process" [process] (ssh (str "ps aux | grep " process))) (deftask :start_ha [] (ssh "/etc/init.d/haproxy start") (call :ps "haproxy"))

• A new function "append" to append a line to a file on remote machines:
  

  (ssh (append "/etc/hosts" "192.168.1.100 web" :sudo true))

• A new function "sed" to replace lines in a file on remote machines,and comm/uncomm to comment/uncomment a line in a file:
  

   (sed <file> <before> <after> :flags <flags> :limit <limit> :backup <backup>) 

  Equivalent to

   sed -i<backup> -r -e "<limit> s/<before>/<after>/<flags>g <filename>"

• Limits max output line to 10000.
