uuencode

This is useful to install a binary from an script like an executable file, a zip or even an rpm. First be sure to have the needed tools installed

 yum -y install sharutils
 

Encode - Binary to text

Suppose we want to encode the `~/.Xauthority` file, the execute in command line

 /usr/bin/uuencode ~/.Xauthority -
 

Note the dash at the end of the command

Decode - Text to binary

Then copy the result string from stdin to your script as follows

 /usr/bin/uudecode > ~/.Xauthority << 'EOF'
 begin 644 -
 M````!'\```$``3``$DU)5"U-04=)0RU#3T]+244M,0`0(581,6(<1J&_0`OE
 M_:%-L@$``!5L;V-A;&AO<W0N;&]C86QD;VUA:6X``3``$DU)5"U-04=)0RU#
 93T]+244M,0`0(581,6(<1J&_0`OE_:%-L@``
 `
 end
 EOF
 

Since this commands yields the result to stdin you should redirect it to a file, specially with decoding process that will generate a binary file.
