Scripting and Task Automation
This article contains detailed description of scripting/automation functionality. You may want to see simplified guide to the functionality instead.
In addition to graphical interface, WinSCP offers scripting/console interface with many commands. The commands can be typed in interactively, or read from script file or another source.
Using scripting interface directly is recommended for simple tasks not requiring any control structures. For complex tasks, using WinSCP .NET assembly is preferred.

Using Scripting
Enter the console/scripting mode by using winscp.com
; or /console
command-line parameter with winscp.exe
. For details see console/scripting command-line parameters.
For automation, commands can be read from a script file specified by /script
switch, passed from the command-line using the /command
switch, or read from standard input of winscp.com
.
The script file must use UTF-8 encoding and must start with UTF-8 BOM (The BOM is not required by the latest beta version anymore).
When running commands specified using /script
or /command
, batch mode is used implicitly and overwrite confirmations are turned off. In an interactive scripting mode, the user is prompted in the same way as in GUI mode. To force batch mode (all prompts are automatically answered negatively) use the command option batch abort
. For batch mode it is recommended to turn off confirmations using option confirm off
to allow overwrites (otherwise the overwrite confirmation prompt would be answered negatively, making overwrites impossible).
Multiple sessions can be opened simultaneously. Use the session
command to switch between them.
Note that the first connection to an SSH server requires verification of the host key. Also the first connection to FTPS or WebDAVS host with certificate signed by untrusted authority requires verification of the certificate.

Checking Results
WinSCP executables return exit code 1 when any command is interrupted due to an error or any prompt is answered Abort (even automatically in batch mode). Otherwise it returns the exit code 0.
To further analyze results of scripted operations, you will find XML logging useful.
Commands Syntax
All WinSCP commands have syntax:
command -switch -switch2 parameter1 parameter2 ... parametern
Command Parameters with Spaces
Command parameters that include space(s) have to be surrounded by double-quotes. To use double-quote literally, double it:
put "file with spaces and ""quotes"".html"
Note that when you are specifying commands on command-line using /command
, you need to surround each command by double-quote and escape the in-command double-quotes by doubling them.
To debug the quoting, enable session logging on level Debug 1 (/loglevel=1
). The log will show how WinSCP understands both your command-line and individual scripting commands.
Environment Variables
You can use environment variables in the commands, with syntax %NAME%
1:
put "%FILE_TO_UPLOAD%"
Note that variable expansion is different than in Windows batch files:
- You cannot use any string processing syntax.
- You cannot use dynamic/pseudo environment variables, such as
%DATE%
or%RANDOM%
. - References to undefined variables are kept intact (not removed).
- You can use
%WINSCP_PATH%
to refer to WinSCP executable path.
Timestamp
WinSCP automatically resolves %TIMESTAMP%
to a real time with format 20141024161712
.2
Advertisement
You can customize the format using syntax %TIMESTAMP#format%
where format
may include yyyy
for year, mm
for month, dd
for day, hh
for hour, nn
for minute and ss
for second. For example %TIMESTAMP#yyyy-mm-dd%
resolves to 2014-10-24
.3 See other formats you can use.
To use %TIMESTAMP%
on command-line in a batch file, you need to escape the %
by doubling it to %%TIMESTAMP%%
, to avoid batch file interpreter trying to resolve the variable.
Script Arguments
You can reference script arguments (passed on command-line using parameter /parameter
) using syntax %N%
, where N
is ordinal number of argument:1
put "%1%"
Case Sensitivity of File Names
Note that WinSCP treats filenames in case sensitive manner. So even if your server treats filenames in case insensitive manner, make sure you specify case properly.4
Commands
The following commands are implemented.
To see help for the command, read respective documentation article below or type command help <command>
directly in console.

Verifying the Host Key or Certificate in Script
The first connection to an SSH server requires verification of the host key. To automate the verification in script, use -hostkey
switch of open
command to accept the expected host key automatically.
You can find the key fingerprint on Server and Protocol Information Dialog. You can also copy the key fingerprint to clipboard from the confirmation prompt on the first (interactive) connection using Copy Key button. Learn more about obtaining host key fingerprint.
FTPS/WebDAVS TLS/SSL certificate signed by untrusted authority may also need to be verified. To automate the verification in script, use -certificate
switch of open
command to accept the expected certificate automatically.
Running a Script under a Different Account (e.g., Using a Scheduler)
If you are going to run the script under a different account (for example using the Windows scheduler), don’t forget that WinSCP still needs to access its configuration. Note that when using registry as configuration storage, the settings are accessible only for your Windows account, so in such a case you may need to either transfer the configuration from your account registry to the other account’s registry or use the INI file instead.
Note that the configuration also includes verified SSH host keys and FTPS/WebDAVS TLS/SSL certificates.
Generating Script
You can have WinSCP generate a script template for you.
Example
In the example below, WinSCP connects to example.com
server with account user
, downloads file and closes the session. Then it connects to the same server with the account user2
and uploads the file back.

# Connect open sftp://user:password@example.com/ -hostkey="ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx" # Change remote directory cd /home/user # Force binary mode transfer option transfer binary # Download file to the local directory d:\ get examplefile.txt d:\ # Disconnect close # Connect as a different user open sftp://user2:password@example.com/ # Change the remote directory cd /home/user2 # Upload the file to current working directory put d:\examplefile.txt # Disconnect close # Exit WinSCP exit
Save the script to the file example.txt
. To execute the script file use the following command.
winscp.com /script=example.txt
For simple scripts you can specify all the commands on command-line using /command
switch:
winscp.com /command "open sftp://user:password@example.com/ -hostkey=""ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx""" "get examplefile.txt d:\" "exit"
In Windows batch file, you can use ^
to split too long command-line to separate lines by escaping following new-line character:
winscp.com /command ^ "open sftp://user:password@example.com/ -hostkey=""ssh-rsa 2048 xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx""" ^ "get examplefile.txt d:\" ^ "exit"
See other useful example scripts.
Converting Script to Code Based on .NET Assembly
When you find yourself limited by scripting capabilities, you may consider converting your script to code that uses WinSCP .NET assembly.
