mac使用初级

imac使用的是login shell，所有开启一个terminal的时候，不会运行.bashrc文件，而是运行.bash_profile文件，因此只需要中home目录新建一个.bash_profile文件，然后在.bash_profile里source .bashrc即可。

imac的terminal中默认没有使用彩色来显示output，可以在.bashrc里输入：

export CLICOLOR=1
export LSCOLORS=ExFxCxDxBxegedabagacad

＃you can use this if you are using a black background:
export LSCOLORS=gxBxhxDxfxhxhxhxhxcxcx

 

截至2015-02-09日，我的.bashrc配置文件如下：

#! /bin/sh

#alias ls='ls -G'
alias grep='grep --color=auto'

export CLICOLOR=1
export LSCOLORS=gxBxhxDxfxhxhxhxhxcxcx

# Terminal colours (after installing GNU coreutils)
NM="\[\033[0;38m\]" #means no background and white lines
HI="\[\033[0;36m\]" #change this for letter colors
HII="\[\033[0;32m\]" #change this for letter colors
SI="\[\033[1;33m\]" #this is for the current directory
IN="\[\033[0m\]"#export PS1="$NM[ $HI\u $HII\h $SI\w$NM ] $IN"
export PS1="$HI\u@$HII\h: $SI\w $NM\$ "

 

OS X Terminal to move the cursor word by word

Out of the box you can use the quite bizarre Esc+F to move to the beginning of the next word and Esc+B to move to the beginning of the current word.

control-w works just fine for me for deleting a word backwards.

还可以在终端的配置中设置 map option key as meta key.

 

mac os运行sshd:

运行 /usr/sbin/sshd ，系统报错：

Could not load host key: /etc/ssh_host_rsa_key

Could not load host key: /etc/ssh_host_dsa_key

生成所需的密钥

/usr/bin/ssh-keygen -t rsa -f /etc/ssh_host_rsa_key

/usr/bin/ssh-keygen -t dsa -f /etc/ssh_host_dsa_key

然后就可以启动 sshd 服务了：

/usr/sbin/sshd
