This question already has an answer here:
I am beginning to learn and love ubuntu. Is there any way to open files like .pdf, .jpeg, .odt, .docx etc. using command line?
For instance, I have a pdf named:
9949107741MathFormulas.pdf in the following directory:
when I go to above directory type
9949107741MathFormulas.pdf to open it, I get the message:
9949107741MathFormulas.pdf: command not found
Please advise, how can this task be accomplished?
