Try this:
Code:
while read LINE; do
 echo $LINE | sed 's/ /%/g'
done < file > file2

When you echo a variable that contains multiple spaces, but you don't enclose the variable in double quotes, the multiple spaces are reduced down to one space. Then you can replace each single space with a percent sign. The resulting lines are placed in file2.

app::clusterssh::host

App::ClusterSSH::Host(3pm)				User Contributed Perl Documentation				App::ClusterSSH::Host(3pm)

NAME

       ClusterSSH::Host - Object representing a host.

SYNOPSIS

	   use ClusterSSH::Host;

	   my $host = ClusterSSH::Host->new({
	       hostname => 'hostname',
	   });
	   my $host = ClusterSSH::Host->parse_host_string('username@hostname:1234');

DESCRIPTION

       Object representing a host.  Include details to contact the host such as hostname/ipaddress, username and port.

METHODS

       $host=ClusterSSH::Host->new ({ hostname => 'hostname' })
	   Create a new host object.  'hostname' is a required arg, 'username' and 'port' are optional.  Raises exception if an error occurs.

       $host->get_hostname
       $host->get_username
       $host->get_port
       $host->get_master
	   Return specific details about the host

       $host->set_username
       $host->set_port
       $host->set_master
	   Set specific details about the host after its been created.

       get_realname
	   If the server name provided is not an IP address (either IPv4 or IPv6) attempt to resolve it and retun the discovered names.

       get_givenname
	   Alias to get_hostname, for use when " get_realname " might return something different

       parse_host_string
	   Given a host string, returns a host object.	Parses hosts such as

       check_ssh_hostname
	   Check the objects hostname to see whether or not it may be configured within the users  $HOME/.ssh/config  configuration file

	   host
	   192.168.0.1
	   user@host
	   user@192.168.0.1
	   host:port
	   [1234:1234:1234::4567]:port
	   1234:1234:1234::4567

	   and so on.  Cope with IPv4 and IPv6 addresses - raises a warning if the IPv6 address is ambiguous (i.e. in the last example, is the
	   4567 part of the IPv6 address or a port definition?) and assumes it is part of address.  Use brackets to avoid seeing warning.
