<1>: How do you know if you have a software installed under Linux?
My system is Red Hat.
I used the command rpm to check if a software was installed (for example: Matlab and fluent) and got the following results:
I use RPM-QA (| grep) MATLAB, no display after carriage return
I used Rpm-qa fluent, and the carriage return did not show any
I used Rpm-qa vasp, and no display after carriage return
But in fact it must have been matlab and fluent, and I use [[email protected]/]# Rpm-q fluent
It shows the package fluent is not installed
MATLAB is the same
In addition, the command [[email protected]/]# man rpm
Returned is No manual entry for rpm
What is this for?

Rpm-qa|grep Package
++++++++++++++++++++++++++++++++++++++++++
Try Yum search with yum command

If you use RPM-IVH matlab to install,
With Rpm-qa | grep matlab is sure to be able to find.
If you are using
Make && make install installed. Then it's better to go straight to the execution.
Find/-name matlab
If loaded, it will tell you which directory the execution program was released to.

Rpm-qa is to see if the software is installed, grep and find are viewing file locations
