Is there a link which will give me the list of RPM packages available for Red hat Linux?
O comando yum list fornecerá uma lista de todos os pacotes disponíveis e yum search permitirá a pesquisa de pacotes. yum list installed mostrará todos os pacotes atualmente instalados no seu sistema.
Por exemplo:
yum search font
and how do I pick up which RPM package for what purpose?
O comando yum info pode fornecer informações sobre um pacote. Por exemplo:
$ yum info openssh
Name : openssh
Arch : x86_64
Version : 6.6.1p1
Release : 33.el7_3
Size : 438 k

I need some BARCODE fonts to be installed on Linux server (Code 128, Code 39 fonts). I need these fonts to be picked by the application reports which will print the barcode for me on the report.
Eu não acredito que existam fontes de código de barras no Red Hat Linux. No entanto, você pode simplesmente baixar fontes apropriadas de outro lugar e instalá-las você mesmo. Existem instruções para instalar fontes aqui .
