Qt apt-get installation script for multiple Linux Distributions

[anshah]

I'm trying to build a Qt install script for multiple Linux distributions. I know that Ubuntu uses "apt-get" repository and RHEL and CentOS use "yum" repository. What's the best way to detect the distribution in my script.

I was thinking something like the following just wanted to know the best way to detect the distro.

if (Ubuntu)
    sudo apt-get install -y [qt package]
else-if (RHEL or CentOS)
    sudo yum -y install [qt package]
endif

I found lsb_release on Ubuntu but not on CentOS. So is there a way to detect whether "yum" or "apt-get" is used?

Hi,

Hope it helps

As you found, lsb_release is not always there. In any case, that approach will require you to pre-enumerate which distros you know about use which, too much work to maintain.

Stick to testing whether apt_get or yum is present, it's much easier, and your script requires it to run anyway. So like:

if [ -f /usr/bin/apt-get ]
then
    sudo apt-get install -y [qt package]
elif [ -f /usr/bin/yum ]
then
    sudo yum -y install [qt package]
fi
