net copy from samba

copy 时有可能会报错是因为没有net use,使用net use 时也可能报错因为之前错误的use过了此时需要的是列出所有的net 然后删除那些出问题的

net use \\IP\shared /user:USER PASSWD
net use rem 列出所有
net use \\IP /del rem 删除

检查进程权限

accesschk.exe -vqp cmd

accesschk

检查进程是否存在

tasklist /FI "IMAGENAME eq myapp.exe"

查看服务信息

 gwmi -Query "select Name,PathName from Win32_Service where PathName like '%venus%'"

进入到回收站

拷贝文件名

资源管理器选择文件按住shift 右键菜单中有copy as path

dumpbin

设置环境变量

wmic-env

rem 好像没有upsert的语法 所以先delete 再create

rem Change the path environment variable values
wmic ENVIRONMENT where "name='path' and username='<system>'" set VariableValue="%path%;e:\tools"
rem Add system environment variables 
wmic ENVIRONMENT create name="home",username="<system>",VariableValue="%HOMEDRIVE%%HOMEPATH%"
rem  Delete the environment variable
wmic ENVIRONMENT where "name='home'" delete
rem set (create or update) env
wmic ENVIRONMENT set name="CUSTOM_EXE_DIR",username="<system>",VariableValue="E:\sm\scripts"
