GitHub has changed the default branch from master to main, but repositories created before the change may still be master. You can git switch them by creating the following alias and running the gitswdb. alias gitswdb="git switch $(git symbolic-ref refs/remotes/origin/HEAD | cut -f4 -d'/')" If you are using git checkout, rewriting switch to checkout should work.

This article is an introduction to searching for a string in a file using ag or pt and specify the matching line to open in JetBrains IDE. The way to open a file from the command line in the JetBrains IDE is the same for all of them, so will use Goland as an example.
