Changes permission bits on the named files (in list) to the bit pattern represented by mode.

mode is the symbolic and absolute mode can be used.

Absolute mode is

FileUtils.chmod 0755, 'somecommand'
FileUtils.chmod 0644, %w(my.rb your.rb his.rb her.rb)
FileUtils.chmod 0755, '/usr/bin/ruby', :verbose => true

Symbolic mode is

FileUtils.chmod "u=wrx,go=rx", 'somecommand'
FileUtils.chmod "u=wr,go=rr", %w(my.rb your.rb his.rb her.rb)
FileUtils.chmod "u=wrx,go=rx", '/usr/bin/ruby', :verbose => true
