How to open txt file in console Terminal or Portainer Docker
I have a project using Asp.Net Core and I deploy it into the Docker container Ubuntu 18.04. I also using NLog to log the error into a txt file.
Now I'm using Portainer to help manage Docker. I want to see all errors have inside of txt file but I don't know how to open it. Please see the image below:
You can see, I have a file with name
ErrorLog.txt. I tried to open it with command
vi ErrorLog.txt but I got an error vi command not found.
Thanks for any suggestions.
To open the file in the terminal or your Portainer.Io you can use
headcommand to do:
head -n -0 ErrorLog.txt
-0 : Allow open all content of that file.
If your file is too long and you only want to get the first 30 lines you can try the command below:
head -n 30 filename.txt
I hope it works for you.Nguyen Truong Giang Feb 27 2021
