I have to versions of a software (Tecplot). When I write "tec360" in the terminal it brings me the old version. How can I change the program call directory so that it will bring me the new version?
Move the new version you have installed to your /opt directory and replace the old one with the new one. Then have a system restart.
something like
sudo mv ~/tecplot /opt/
If you are not root , then do as follows in your terminal
gedit .bashrc
write a line at the end of the opened text file as
alias tec360="~/tp/bin/tec360"
Then save and close the text file.
Then in the terminal write as
source ~/.bashrc
now try again by calling your program.
