Mac Use Note

This post notes points since Mac 10.12.2

  • problem like Permission denied - /usr/local/lib/perl5 and with not symlinked into /usr/local.

As we can not use sudo brew, /usr/local is only readable for normal use. Thus we can not build soft link. First we need:

    sudo chown -R $USER:admin /usr/local

to change the write permission, and then build the link

    brew link --overwrite git
  • Add Color to the Terminal

In ‘~/.bashrc’ (in my mac, I’ve soft linked ~/.bashrc to ~/.bash_profile), add the following scripts

    export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$ "
    export CLICOLOR=1
    export LSCOLORS=GxFxCxDxBxegedabagaced
    alias ls='ls -GFh'

for Dark terminal themes, and the following alalternative for Light terminal theme,

    export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\]\$ "
    export CLICOLOR=1
    export LSCOLORS=ExFxBxDxCxegedabagacad
    alias ls='ls -GFh'

And add color for grep command:

    export GREP_OPTIONS='--color=auto'
    alias grep='grep -n'        #print line number of matched lines
