Compare two file (please help me it's deadly urgent)
I have many files with info about soft, installed on remote machines.
I need to compare this file with template (soft than must be installed) and output file must content info about software that's not installed.
Code:
template.txt
software_name1
software_name2
software_name3.1

Code:
workstation1_info.txt
software_name3.2
Lantronix
..any other software
software_name1

output must be software_name2, becouse it is not installed, but software_name3.2 is good enough becouse version is more than we need.
So, the task is to show lines that is in template and not in source, using simple regular expressions

I use grep
Code:
grep -vxf template source >out

or
Code:
grep -Fvf template source >out

But it shows me only lines that is in source and not in template etc...

I need so fast to solve this problem, becouse it is deadly urgent case.
Please help me.

Hi.
there's two much different version and packages of software...
So I don't know what the name of it will be in source file.
I know that version of some soft must be >5.x.x.

In output I need lines from template that do not match any lines from inventory
