[SOLVED] Finding which compilers are installed on CentOS

OtagoHarbour · 09-20-2014, 11:29 AM

I am using CentOS 6.5 and would like a shell command to see which compilers are installed. On Debian, I obtained such a list using

Code:

sudo dpkg --list | grep compiler

However, on CentOS, this resulted in

Code:

sudo: dpkg: command not found

Code:

sudo yum install dpkg

resulted in

Code:

No package dpkg available.

Next to distro-agnostic local commands like whatis, whereis, which, locate, 'man -k' or apropos the main source of information should be https://www.centos.org/docs/ and wiki.centos.org/Documentation. Reading it (try it!) explains CentOS package management is RPM. Most package management tasks can be done using the 'rpm' command and its Yum front-end. RPM categorizes "sets of packages" into groups. You can find the list in /usr/share/doc/rpm*/GROUPS. (Note the RPM definition of groups does not necessarily equal the Yum one.) One of them is called "Development". 'man rpm' (try it!) explains querying in rpm requires "-q" and to select by group you use "-g". The result should be something like

Code:

rpm -q -g "Development/Languages"

or maybe

Code:

rpm -q -g "Development/Languages" --qf="%{name}\n"|sort|nl

Thank you for your reply. The latter call worked (didn't need the |nl). It showed some application that were not installed. I checked whether they were with whereis.

Thanks,
