[FreeBSD]_[Shell编程]

虽然说bsd比较安全严谨,但是linux的可定制性更高,所以还是比较喜欢linux.

1.Vi

vi的删除字符和MacOS不一样了，是进入normal模式然后用x来删.

2.修改默认csh Shell为Bash Shell

1. 安装 bash
代码:
# cd /usr/ports/shells/bash
# make install clean

2. 将 shell 改成 bash 代码:
# chsh <== 这个指令就是 change shell 的意思

代码:
#Changing user database information for root.
