Windows Command Line cheatsheet (part 1): some useful tips
Yes, also Windows can be used by command line…
Today I propose a brief list of useful Windows CLI commands for daily use
Adding Keys and Values
C:>reg add [\TargetIPaddr][RegDomain][Key]
Add a key to the registry on machine [TargetIPaddr] within the registry domain [RegDomain] to location [Key].
If no remote machine is specified, the current machine is assumed.
Export and Import
C:>reg export [RegDomain][Key] [FileName]
Export all subkeys and values located in the domain [RegDomain] under the location [Key] to the file [FileName]
C:>reg import [FileName]
Import all registry entries from the file [FileName].
Import and export can only be done from or to the local machine.
Query for a specific Value of a Key
C:>reg query [\TargetIPaddr][RegDomain][Key] /v [ValueName]
Query a key on machine [TargetIPaddr] within the registry domain [RegDomain] in location [Key] and get the specific value [ValueName] under that key.
Add /s to recurse all values.
C:>wmic [alias] [where clause] [verb clause]
- qfe (Quick Fix Engineering — shows patches)
Example [where clauses]:
- where name=”nc.exe”
- where (commandline like “%stuff”)
- where (name=”cmd.exe” and parentprocessid!=”[pid]”)
Example [verb clauses]:
- list [full|brief]
- get [attrib1,attrib2…]
- call [method]
List all attributes of [alias]:
C:> wmic [alias] get /?
List all callable methods of [alias]:
C:>wmic [alias] call /?
List all attributes of all running processes:
C:>wmic process list full
Make WMIC effect remote[TargetIPaddr]:
C:>wmic /node:[TargetIPaddr] /user:[User] /password:[Passwd] process list full
Processes and Services
List all processes currently running:
List all processes currently running and the DLLs each has loaded:
Lists all processes currently running which have the specified [dll] loaded:
C:>tasklist /m [dll]
List all processes currently running and the services hosted in those processes:
Query brief status of all services:
Query the configuration of a specific service:
C:>sc qc [ServiceName]
File Search and Counting Lines
Search directory structure for a file in a specific directory:
C:>dir /b /s [Directory][FileName]
Count the number of lines on StandardOuy of [Command]:
C:>[Command] | find /c /v “”
Finds the count (/c) of lines that do not contain (/v) nothing (“”).
Lines that do not have nothing are all lines, even blank lines, which contain CR/LF
Command line FOR loops
C:>for /L %i in([start],[step],[stop]) do [command]
Set %i to an initial value of [start] and increment it by [step] at every iteration until its value is equal to [stop].
For each iteration, run [command].
The iterator variable %i can be used anywhere in the command to represent its current value.
Iterate over file contents
C:>for /F %i in ([file-set]) do[command]
Iterate through the contents of the file on a line-by-line basis.
For each iteration, store the contents of the line into %i and run [command].
Useful NETSTAT syntax
Show all TCP and UDP port usage and process ID:
Look for usage of port [port] every [N] seconds:
C:>netstat –nao [N] | find [port]
Dump detailed protocol statistics:
C:>netstat –s –p [tcp|udp|ip|icmp]
Useful NETSH syntax
Turn off built-in Windows firewall:
C:>netsh firewall set opmode disable
Configure interface “Local Area Connection” with [IPaddr] [Netmask] [DefaultGW]:
C:>netsh interface ip set address local static [IPaddr] [Netmask] [DefaultGW] 1
Configure DNS server for “Local Area Connection”:
C:>netsh interface ip set dns local static [IPaddr]
Configure interface to use DHCP:
C:>netsh interface ip set address local dhcp
