Installing YAML Perl module

YAML, which is a recursive acronym for ""YAML Ain't Markup Language", is a human-readable data serialization format that incorporates concepts from programming languages such as C, Perl, and Python. To install the YAML Perl module type perl -e shell -MCPAN at a shell prompt and then at the cpan prompt, type install YAML.
# perl -e shell -MCPAN
Terminal does not support AddHistory.

cpan shell -- CPAN exploration and modules installation (v1.9800)
Enter 'h' for help.

cpan[1]> install YAML

Once it is installed you can view documentation on it by issuing the command perldoc YAML. If you just want to see if it is installed, you can issue that command. If it is, you will see the documentation. If it isn't installed, you will see a message "No documentation found" followed by the module name.

You can also use the -l argument to perldoc, which will report the location of the Plain Old documentation, abbreviated pod, file for the module, if one is present or also report "No documentation found", if the module can't be found. Be sure to capitalize "YAML" or you will see the "No documentation found" message.

# perldoc -l yaml
No documentation found for "yaml".
# perldoc -l YAML
/usr/local/share/perl5/YAML.pod
