The Silver Searcher
The Silver Searcher is a tool for searching code. It started off as a clone of Ack, but their feature sets have since diverged slightly. In typical usage, Ag is 5-10x faster than Ack. See the GitHub page for more info.

就是类似Ack(Ruby实现)，但是用c实现的，所以更快。

安装 ag(the silver searcher)

brew install the_silver_searcher


卸载ag

brew uninstall the_silver_searcher


如果出现权限问题， 如 cannot write之类 可以：

sudo chown -R David /usr/local


我在安装ag时，出现了 error “/usr/local/bin is not writable”

sudo chown -R David /usr/local/bin
sudo chown -R David /usr/local/share


当 brew install the_silver_searcher Warning: the_silver_searcher-0.31.0 already installed, it’s just not linked

可以：

brew link the_silver_searcher


更新于2016.04.08

我的mac使用的bash是zsh，

当用ag时，报错：

zsh:command not found:ag

解决办法：

cd ~
ls -a
vim .zshrc


.zshrc是zsh shell的配置文件。

我这边是在line58的 PATH加入了我的homebrew/bin的路径

/usr/local/homebrew/bin

重启terminal就ok了。
