uuencode
This is technique is useful to embed a binary file on a script. First ensure to have the proper package installed
yum -y install sharutils
How to encode binary files to text
Execute the following command
/usr/bin/uuencode /path/to/binary/file -
Note the hyphen at the end of the command
How to decode text files to binary
To restore a binary file from text copy the result string from stdin to your script as follows
/usr/bin/uudecode > /path/to/binary/file << '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
The output of the above command always must be redirected to a file.
