- unpackself - have chocolatey set itself up
- version - [DEPRECATED] will be removed in v1 - use
cup <pkg|all> -whatifinstead

How To Pass Options / Switches
You can pass options and switches in the following ways:
- Unless stated otherwise, an option/switch should only be passed one
time. Otherwise you may find weird/non-supported behavior.
--(one character switches should not use
- Option Bundling / Bundled Options: One character switches can be
(confirm yes) can be bundled as
- NOTE: If
verboseare bundled with local options
(not the global ones above), some logging may not show up until after
the local options are parsed.
- Use Equals: You can also include or not include an equals sign
=between options and values.
- Quote Values: When you need to quote an entire argument, such as
when using spaces, please use a combination of double quotes and
"'value'"). In cmd.exe you can just use double quotes
"value") but in powershell.exe you should use backticks
`"value`") or apostrophes (
'value'). Using the combination
allows for both shells to work without issue, except for when the next
- Pass quotes in arguments: When you need to pass quoted values to
to something like a native installer, you are in for a world of fun. In
cmd.exe you must pass it like this:
-ia "/yo=""Spaces spaces""". In
PowerShell.exe, you must pass it like this:
-ia '/yo=""Spaces spaces""'.
No other combination will work. In PowerShell.exe if you are on version
v3+, you can try
-iato just pass the args through as is,
which means it should not require any special workarounds.
- Periods in PowerShell: If you need to pass a period as part of a
value or a path, PowerShell doesn't always handle it well. Please
quote those values using "Quote Values" section above.
- Options and switches apply to all items passed, so if you are
installing multiple packages, and you use
is going to look for and try to install version 1.0.0 of every
package passed. So please split out multiple package calls when
wanting to pass specific options.
Scripting / Integration - Best Practices / Style Guide
When writing scripts, such as PowerShell scripts passing options and
switches, there are some best practices to follow to ensure that you
don't run into issues later. This also applies to integrations that
are calling Chocolatey and parsing output. Chocolatey uses
PowerShell, but it is an exe, so it cannot return PowerShell objects.
Following these practices ensures both readability of your scripts AND
compatibility across different versions and editions of Chocolatey.
Following this guide will ensure your experience is not frustrating
based on choco not receiving things you think you are passing to it.
- For consistency, always use
choco.exe. Never use
shortcut commands like
- Always have the command as the first argument to
choco. e.g. [choco install
](/docs/commandsinstall), where [install`](/docs/commandsinstall) is the command.
- If there is a subcommand, ensure that is the second argument. e.g.
choco source list, where
sourceis the command and
- Typically the subject comes next. If installing packages, the
subject would be the package names, e.g.
choco install pkg1 pkg2.
- Never use 'nupkg' or point directly to a nupkg file UNLESS using
'choco push'. Use the source folder instead, e.g.
choco install <package id> --source="'c:\folder\with\package'"instead of
choco install DoNotDoThis.1.0.nupkgor
choco install DoNotDoThis --source="'c:\folder\with\package\DoNotDoThis.1.0.nupkg'".
- Switches and parameters are called simply options. Options come
after the subject. e.g.
choco install pkg1 --debug --verbose.
- Never use the force option (
-f) in scripts (or really
otherwise as a default mode of use). Force is an override on
Chocolatey behavior. If you are wondering why Chocolatey isn't doing
something like the documentation says it should, it's likely because
you are using force. Stop.
- Always use full option name. If the short option is
-n, and the
full option is
--name. The only acceptable short
option for use in scripts is
-y. Find option names in help docs
online or through
choco [Command Name] -?.
- For scripts that are running automated, always use
-y. Do note
that even with
-ypassed, some things / state issues detected will
temporarily stop for input - the key here is temporarily. They will
continue without requiring any action after the temporary timeout
(typically 30 seconds).
- Full option names are prepended with two dashes, e.g.
--debug --verbose --ignore-proxy.
- When setting a value to an option, always put an equals (
between the name and the setting, e.g.
- When setting a value to an option, always surround the value
properly with double quotes bookending apostrophes, e.g.
- If you are building PowerShell scripts, you can most likely just
simply use apostrophes surrounding option values, e.g.
- Prefer upgrade to install in scripts. You can't
installto a newer
version of something, but you can
choco upgradewhich will do both
upgrade or install (unless switched off explicitly).
- If you are sharing the script with others, pass
explicit about where the package is coming from. Use full link and
not source name ('https://chocolatey.org/api/v2' versus
- If parsing output, you might want to use
get output in a more machine parseable format. NOTE: Not all
commands handle return of information in an easily digestible
- Use exit codes to determine status. Chocolatey exits with 0 when
everything worked appropriately and other exits codes like 1 when
things error. There are package specific exit codes that are
recommended to be used and reboot indicating exit codes as well. To
check exit code when using PowerShell, immediately call
$exitCode = $LASTEXITCODEto get the value choco exited with.
Here's an example following bad practices (line breaks added for
choco install pkg1 -y -params '/Option:Value /Option2:value with spaces' --c4b-option 'Yaass' --option-that-is-new 'dude upgrade'
Now here is that example written with best practices (again line
breaks added for readability - there are not line continuations
choco upgrade pkg1 -y --source="'https://chocolatey.org/api/v2'" --package-parameters="'/Option:Value /Option2:value with spaces'" --c4b-option="'Yaass'" --option-that-is-new="'dude upgrade'"
Note the differences between the two:
- Which is more self-documenting?
- Which will allow for the newest version of something installed or
upgraded to (which allows for more environmental consistency on
packages and versions)?
- Which may throw an error on a badly passed option?
- Which will throw errors on unknown option values? See explanation
Chocolatey ignores options it doesn't understand, but it can only
ignore option values if they are tied to the option with an
equals sign ('='). Note those last two options in the examples above?
If you roll off of a commercial edition or someone with older version
attempts to run the badly crafted script
--c4b-option 'Yaass' --option-that-is-new 'dude upgrade', they are likely to see errors on
'Yaass' and 'dude upgrade' because they are not explicitly tied to the
option they are written after. Now compare that to the other script.
Choco will ignore
--option-that-is-new="'dude upgrade'" as a whole when it doesn't
register the options. This means that your script doesn't error.
Following these scripting best practices will ensure your scripts work
everywhere they are used and with newer versions of Chocolatey.

Default Options and Switches
NOTE: Options and switches apply to all items passed, so if you are
running a command like install that allows installing multiple
packages, and you use
--version=1.0.0, it is going to look for and
try to install version 1.0.0 of every package passed. So please split
out multiple package calls when wanting to pass specific options.
