shell script
shell script (application/x-shellscript) 参考：Shell 教程 Shell 是一个用 C 语言编写的程序，它是用户使用 Linux 的桥梁。Shell 既是一种命令语言，又是一种程序设计语言。 Shell 是指一种应用程序，这个应用程序提供了一个界面，用户通过这个界面访问操作系统内核的服务。 Ken Thompson 的 sh 是第一种 Unix Shell，Windows Explorer 是一个典型的图形界面 Shell。 Shell 脚本（shell script），是一种为 shell 编写的脚本程序。 业界所说的 shell 通常都是指 shell 脚本，但读者朋友要知道，shell 和 shell script 是两个不同的概念。 由于习惯的原因，简洁起见，本文出现的 “shell编程” 都是指 shell 脚本编程，不是指开发 shell 自身。
1、确认Linux 的 Shell 种类众多，常见的有：Bourne Again Shell（/bin/bash） ，由于易用和免费，Bash 在日常工作中被广泛使用。同时，Bash 也是大多数Linux 系统默认的 Shell。 2、CDS的电路图捕获，仿真，版图和验证 3、设置LISCENCE,减少检索时间 4、仿真入口 5、CDS中一些会被使用的变量：64位 对于一个cadence IC来说，他和一个工艺库建立连接的方式便是通过一个cds.lib的数据进行指引。所以cds.lib本质上来说，只是一个包含库路径的数据引导文本。 6、设置在系统路径之前。

export PAT
Linux export 命令用于设置或显示环境变量。
在 shell 中执行程序时，shell 会提供一组环境变量。export 可新增，修改或删除环境变量，供后续执行的程序使用。export 的效力仅限于该次登陆操作。
export [-fnp][变量名称]=[变量设置值]
参考：Linux export 命令
列出环境变量

csmc symbol库在08或者09文件夹，b开头的是已经装好的器件库。

drc文件要改路径，calibre放哪里啊，pdk还是IC616下面，是改这个文件里的路径，
官网给的工艺库只有M1,M2和TM三层金属
gvim
