can TC be installed in a linux environment

Hi,

 

No it cannot as it was already said by others, but it is possible to execute commands on the linux machine from TestComplete test code and obtain results. E.g.: https://community.smartbear.com/t5/TestComplete-Functional-Web/Executing-UNIX-commands-through-SSH-in-TestComplete/m-p/61001#M2316

(The more you describe the actual task/plan/need, the more useful answer you might receive...)
