Why won't ngrok linux start?

Question

linux

I downloaded ngrok for linux in .tgz format and unpacked it with the "tar -xvzf file.tgz" command. After that, when I try to enter "ngrok authtoken ****** ", I get the message that the "ngrok" command was not found. Did you mean:

Although I am in the same directory with the ngrok file

Sorry if this is a dumb question but I already searched the internet as best I could

Answer 1

Although I am with the ngrok file in the same directory

add a ./ without a space before the command. Those. ./ngrok ...etc.
