Git⚑

• New: Pre-commit.

  pre-commit/pre-commit is a framework for managing and maintaining multi-language pre-commit hooks.

  You can skip specific hooks with:

  SKIP=no-commit-to-branch pre-commit run --all-files
  

  Which is useful if a CI runs for the main branch so that it doesn't complain about running in it.

netcat⚑

• New: Test TCP connections.

  nc -v -z -w 3 [host] [port]
  

  Options: * -v: verbose * -z: just check if the port is open and exit (without sending any data) * -w 3: 3 seconds timeout

  If it exists with return code 0, it means that the connection succeeded.

wget⚑

• New: Redirect output to stdout.

  wget -qO- [url]
