The Steam Console Client or SteamCMD is a command-line version of the Steam client. Its primary use is to install and update various dedicated servers available on Steam using a command-line interface. It works with games that use the SteamPipe content system. All games have been migrated from the deprecated HLDSUpdateTool to SteamCMD.

1. Create a folder for SteamCMD.
2. Download SteamCMD for Windows: https://steamcdn-a.akamaihd.net/client/installer/steamcmd.zip
3. Extract the contents of the zip to the folder.
1. Before you begin, you must first install the dependencies required to run SteamCMD:
sudo apt-get install lib32gcc1
yum install glibc libstdc++
yum install glibc.i686 libstdc++.i686
2. Create a user account named steam to run SteamCMD safely, isolating it from the rest of the operating system. Do not run steamcmd while operating as the root user - to do so is a security risk.
As the root user, create and escalate to the steam user:
useradd -m steam su - steam
If you're not logging in as root and you instead use
sudo to perform administration, create and escalate to the steam user as follows:
sudo useradd -m steam sudo -iu steam
3. Create a directory for SteamCMD and switch to it.
mkdir ~/steamcmd && cd ~/steamcmd
3. Download and extract SteamCMD for Linux.
curl -sqL 'https://steamcdn-a.akamaihd.net/client/installer/steamcmd_linux.tar.gz' | tar zxvf -
1. Open Terminal.app and create a directory for SteamCMD.
mkdir ~/steamcmd && cd ~/steamcmd
2. Download and extract SteamCMD for OS X.
curl -sqL 'https://steamcdn-a.akamaihd.net/client/installer/steamcmd_osx.tar.gz' | tar zxvf -
On first run, SteamCMD will automatically update and enter you into a
Steam> prompt. Type
help for more information.
Open a Command Prompt and start SteamCMD.
cd C:\steamcmd steamcmd
Open a terminal and start SteamCMD.
cd ~/steamcmd ./steamcmd.sh
To download most game servers, you can login anonymously.
With a Steam account
Some servers require you to login with a Steam Account.
Next enter your password.
If Steam Guard is activated on the user account, check your e-mail for a Steam Guard access code and enter it. This is only required the first time you log in (as well as when you delete the files where SteamCMD stores the login information).
You should see a message stating that you have successfully logged in with your account.
Downloading an app
1. Start SteamCMD and log in.
2. Set your app install directory. (Note: use forward slashes for Linux/OS X and backslashes for Windows.)
e.g. a directory named
cs_go inside the current directory:
For Windows: force_install_dir c:\cs_go\
3. Install or update the app using the
app_update command (supplying a Steam Application ID). To also validate the app, add
validate to the command. To download a beta branch, use the
-beta <betaname> option – for example, the HLDS beta branch is named
beta and the SrcDS beta branch is named
prerelease. Some beta branches are protected by a password; to be able to download from them, also add the
-betapassword <password> option.
app_update <app_id> [-beta <betaname>] [-betapassword <password>] [validate]
HLDS is a special case: the App ID is always 90 and a mod must be chosen first. This is done by setting the app config option
mod to the requested value.
app_set_config <app_id> <option_name> <option_value>
- Example: Install and validate the Counter Strike: Global Offensive dedicated server:
app_update 740 validate
- Example: Install and validate HLDS with Team Fortress Classic:
app_set_config 90 mod tfc app_update 90 validate
app_updatecommand before all the required files are successfully installed. Simply run
app_update 90 validatemultiple times until no more updates take place.
- Example: Install and validate beta version of HLDS (Half-Life):
app_update 90 -beta beta validate
- Example: install and validate beta version of the Counter Strike: Source dedicated server:
app_update 232330 -beta prerelease validate
- Example: install and validate a private beta version of the Natural Selection 2 dedicated server (name
- [beta name] is the name of the private beta branch
- [beta code] is the password for the private beta branch
app_update 4940 -beta alpha -betapassword natsel validate
3. Once finished, type
quit to properly log off of the Steam servers.
Validate is a command that will check all the server files to make sure they match the SteamCMD files. This command is useful if you think that files may be missing or corrupted.
mapcycle.txt, this file will be overwritten to the server default. Any files that are not part of the default installation will not be affected.
It is recommended you use this command only on initial installation and if there are server issues.
A list of known servers that use SteamCMD to install is available on the Dedicated Servers List page. Note that any extra commands listed need to be executed before the app_update line.
There are two ways to automate SteamCMD. (Replace
./steamcmd.sh on Linux/OS X.)
-betaoption on the command line, it must be quoted in a special way, such as
+app_update "90 -beta beta".
"+app_update 90 -beta beta"instead.
Append the commands to the command line prefixed with plus characters, e.g.:
steamcmd +login anonymous +force_install_dir ../csgo_ds +app_update 740 +quit
To install a specific game mod for HL1, such as Counter-Strike: Condition Zero:
steamcmd +login anonymous +force_install_dir ../czero +app_set_config 90 mod czero +app_update 90 +quit
For a game that requires logins, like Killing Floor:
steamcmd +login <username> <password> +force_install_dir c:\KFServer\ +app_update 215350 +quit
Creating a script
1. Put your SteamCMD commands in a text file. (You may add comments which start with
// update_csgo_ds.txt // @ShutdownOnFailedCommand 1 //set to 0 if updating multiple servers at once @NoPromptForPassword 1 login <username> <password> //for servers which don't need a login //login anonymous force_install_dir ../csgo_ds app_update 740 validate quit
2. Run SteamCMD with the
+runscript option, referring to the file you created previously. Example:
steamcmd +runscript csgo_ds.txt
It is possible to choose the platform for which SteamCMD should download files, even if it isn't the platform it is currently running on. This is done using the
@sSteamCmdForcePlatformType variable. (Yes, those are two "s"es at the beginning of the variable name.) For example, to download the Windows CSGO dedicated server on Linux, you can run the following command:
./steamcmd.sh +@sSteamCmdForcePlatformType windows +login anonymous +force_install_dir ../csgo_ds +app_update 740 validate +quit
or use the following script:
@ShutdownOnFailedCommand 1 @NoPromptForPassword 1 @sSteamCmdForcePlatformType windows login anonymous force_install_dir ../csgo_ds app_update 740 validate quit

This script will automate the process of installing SteamCMD with the optional choice of installing a game. This script is currently tested on Ubuntu but confirmed working on Ubuntu,Mint,centos,ZorinOS and debian
How to Install
- Firstly create a user for SteamCMD “adduser steam”.
- Create a new file using nano or vi called “steamcmdinstaller.sh ".
- Find most recent version of steamcmdinstaller.sh from https://github.com/Gousaid67/steam-cmd-installer and paste it in to the newly created file.
- Make the script executable with chmod +x steamcmdinstaller.sh .
- Run the script ./steamcmdinstaller.sh . You will be prompted to enter various settings.
- The script will now automatically download and install SteamCMD. You will also have the option to install a game server of your choice by giving it an appid.
Optional: define a custom path
The script can use custom path outside of /home/user/ but it require editing the script. Thanks to dvdvideo1234 for his help on that feature
- do the 4 first step indicated up there.
- then do ./"scriptname".sh "custom path" and follow the usual instruction. the script will not work if you set path on restricted directories such as /etc
SteamCMD Guardian 1.2
The following script was tested on Debian Wheezy.
View and download here: http://pastebin.com/hcpMpmaZ
To make this script work, we need a location. Preferably you created a user (e.g. steam) with it's own home directory (/home/steam) and are logged in as it via SSH, tty or using su.
- Make the file.
- Paste in the code
- Modify the code, add at least 1 game to the
- Close the file with + , followed by and concluding with + .
- Give the file execute rights for the user
chmod u+x ./updateserver.sh
- Run the file
The file will auto-download SteamCMD, update it and install all chosen games (up to 4). Run the file again to update the games.
ERROR! Failed to install app 'xxxxxx' (No subscription)
If you get the 'No subscription' error, the game/server you are trying to download either requires a login or that you have purchased the game. You will therefore have to log in with a Steam username and password – if that doesn't help, you may need to purchase a copy of the game on Steam first. See Dedicated Servers List.
steamcmd +login <username> <password>
32-bit libraries on 64-bit Linux systems
Since SteamCMD is a 32-bit binary, 32-bit libraries are required.
The following error may occur:
steamcmd: error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
The resolution depends on your distro:
Debian based distributions (Ubuntu, Mint, etc.)
sudo apt-get install lib32stdc++6
ia32-libsare not required to install SteamCMD;
With Debian 7 "Wheezy" you may encounter this error:
The following packages have unmet dependencies: ia32-libs : Depends: ia32-libs-multiarch but it is not installable E: Unable to correct problems, you have held broken packages.
To fix this, do the following:
dpkg --add-architecture i386 apt-get update apt-get install lib32gcc1
Red Hat based distributions (RHEL, Fedora, CentOS, etc.)
yum install glibc.i686 libstdc++.i686
Don't forget to first enable the multilib repository.
pacman -S lib32-gcc-libs
Login Failure: No Connection
On linux servers, you may experience a "Login Failure: No Connection" error. This is related to missing iptables rules. You will want something along these lines:
iptables -A INPUT -p udp -m udp --sport 27000:27030 --dport 1025:65355 -j ACCEPT iptables -A INPUT -p udp -m udp --sport 4380 --dport 1025:65355 -j ACCEPT
The port list is found here: https://support.steampowered.com/kb_article.php?ref=8571-GLVN-8711&l=english
On Windows servers, you may experience "SteamUpdater: Error: Download failed: http error 0" and "SteamUpdater: Error: Steam needs to be online to update. Please confirm your network connection and try again.". This is usually fixed by checking "Automatically detect settings" in IE (Internet Explorer) through the lan settings in the Internet option menu.
- Open Internet Explorer (IE).
- Click on Tools → Internet Options
- Click on the Connections tab
- At the bottom, you should see Local Area Network (LAN) Settings.
- Check the first box (Automatically detect settings)
- Hit OK, and Apply. Try running the SteamCMD again; if it still doesn't work. try lowering your Internet Security level zone to medium or lower. You can find that in the Security tab in Internet Options.
SteamCMD startup errors
Unable to locate a running instance of Steam
You may get the following error when starting a server with Linux:
[S_API FAIL] SteamAPI_Init() failed; unable to locate a running instance of Steam, or a local steamclient.dll.
Resolve the issue by linking
steamclient.so to the
ln -s steamcmd/linux32/steamclient.so ~/.steam/sdk32/steamclient.so
ulimit Linux startup error
Some users may get a
ulimit error (no permission/cannot open file) while script is starting up. This error caused by a low setting of the
-n parameter (number of file descriptors) of
ulimit. SteamCMD uses standard commands inside of the initialization shell script to change the
ulimit automatically, but some servers may forbid increasing
ulimit values after startup (or beyond a limit set by
This can be fixed by changing the file descriptor number ulimit:
ulimit -n 2048
If an error appears (no permission), you will have to log in as root to change the parameter. To check the current setting, type ulimit -a; the system will reply with many rows, you need to find one:
open files (-n) 1024
In this case, 1024 is the current value.
root can also modify the limits in the
In most instances you will simply get a warning message however it will not stop SteamCMD from running.
Only the HLDS engine is downloaded
When trying to download a HL1 mod like TFC, initially it only downloads the engine files of the HLDS, but not the mod. This happens with both the regular version and the beta. You may have to try multiple times until all the required files are downloaded, but once this is done, the files should update correctly next time.
Work-around for this issue here: http://danielgibbs.co.uk/2013/11/hlds-steamcmd-workaround-appid-90/
Just deleting the appmanifest files, without downloading replacements from a third party, may work as well! You will get an error at first though, complaining that something went wrong, which is due to the deleted files.
On a side note, for some reason CS is always installed as well.
