  • sudo macchanger -r en0

3 Brew

  • Help

    • brew --version Display the version of Homebrew.

    • brew help Print Help Information

    • brew help <sub-command> Print Help Info for a brew command

    • brew doctor Check system for potential problems.

  • Update

    • brew update Fetch latest version of homebrew and formula

    • brew outdated Show formulae with an updated version available

    • brew upgrade Upgrade all outdated and UN pinned brews

    • brew upgrade <formula> Upgrade only the specified brew

    • brew pin <formula> Prevent the specified formulae from being upgraded

    • brew unpin <formula> Allow the specified formulae to be upgraded.

  • Repositories

    • brew tap List all the current tapped repositories (taps)

    • brew tap <user/repo> Tap a formula repository from Github using https for tap https://github.com/user/homebrew-repo

    • brew tap <user/repo> <URL> Tap a formula repository from the specified URL

    • brew untap <user/repo> Remove the given tap from the repository

  • Cask

    • brew tap homebrew/cask Tap the Cask repository from Github.

    • brew search <text> Search all known casks based on the substring text.

  • Cleanup

    • brew cleanup Remove older versions of installed formulae.

    • brew cleanup <formula> Remove older versions of specified formula.

    • brew cleanup -n Display all formula that will be removed (dry run)

  • Shell Environment Variables

    • Add the following in the shell init file, ~/.bash_profile

export MANPATH="/usr/local/share/man:$MANPATH"
export INFOPATH="/usr/local/share/info:$INFOPATH"

And then make sure that the emacs package exec-path-from-shell is available and the emacs variable exec-path-from-shell-variables contains both of “PATH” and “MANPATH”. We need this to ensure that Emacs man directs to the man pages of applications installed by Brew. For example, macos native bash is very old but we can get newer version of bash (that will be located under /usr/local) through brew. This causes a conflict between older and newer versions of man pages. By setting MANPATH="/usr/local/share/man:$MANPATH" I could make sure that the man page for newer bash is accessed by man bash. If we do MANPATH="$MANPATH:/usr/local/share/man", then the newer bash might get lower priority.

Python has been installed as
  /usr/local/bin/python3

Unversioned symlinks `python`, `python-config`, `pip` etc. pointing to
`python3`, `python3-config`, `pip3` etc., respectively, have been installed into
  /usr/local/opt/python/libexec/bin

You can install Python packages with
  pip3 install <package>
They will install into the site-package directory
  /usr/local/lib/python3.7/site-packages

gnu-getopt is keg-only, which means it was not symlinked into /usr/local,
because macOS already provides this software and installing another version in
parallel can cause all kinds of trouble.

If you need to have gnu-getopt first in your PATH run:
  echo 'export PATH="/usr/local/opt/gnu-getopt/bin:$PATH"' >> /Users/hbshim/.bash_profile

SIGSTOP

Stop the process

  • SIGSTOP makes the operating system pause a process’s execution. The process cannot ignore the signal.

  • SIGKILL forces the process to stop executing immediately. The process cannot ignore this signal. This process does not get to clean-up either.

  • SIGTERM requests a process to stop running. This signal can be ignored. The process is given time to gracefully shutdown so that it can save its progress and release resources.

  • SIGINT is very similar to SIGTERM and equivalent to pressing Control-C key on the terminal.
