常用的终端指令

一、使用framework的相关指令

1. 查看framework包,执行文件类型

• lipo -info + 文件路径

2. 按类型抽取数据

• lipo 文件路径 -thin 类型 -output 输出路径

3. 合并

• lipo -create 文件路径1 文件路径2 -output 输出路径

4.在创建文件的时候提示你没有操作权限：

E325: ATTENTION
Found a swap file by the name ".application.properties.swp"
          owned by: wasadmin   dated: Tue Nov 29 14:31:30 2016
         file name: /opt/IBM/WebSphere/AppServer/profiles/AppSrv03/installedApps/B2C-WAP-API-2Node03Cell/airchina_war.ear/airchina.war/WEB-INF/config/application.properties

(1) Another program may be editing the same file.
    If this is the case, be careful not to end up with two
    different instances of the same file when making changes.
    Quit, or continue with caution.
 
(2) An edit session for this file crashed.
    If this is the case, use ":recover" or "vim -r application.properties"
    to recover the changes (see ":help recovery").
    If you did this already, delete the swap file ".application.properties.swp"
    to avoid this message.
 
Swap file ".application.properties.swp" already exists!
[O]pen Read-Only, (E)dit anyway, (R)ecover, (Q)uit, (A)bort

有三种可能:

1. 该错误为当前用户没有权限对文件作修改,你有权限修改文件吗？如果是root权限，可以:wq! 强行保存退出；

2. 该文件没有正确保存退出，正在打开状态，请别人关闭后再保存；

3. 若该文件所有人都关闭了，提示有的人没有关闭，则删除该文件的临时文件则可以正常打开、修改、保存；

解决方法
强制保存 --> ':wq!'
