Terminal profiles are platform-specific shell configurations comprised of
an executable path, arguments, and other customizations. By default
several profiles are automatically detected which can be customized or
added to.
Example profile:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"Custom Init": {
` `"path": "pwsh.exe",
` `"args": [` `"-noexit",
` `"-file",
` `"${env:APPDATA}\\PowerShell\\custom-init.ps1"
` `]
` `}
` `},
` `"terminal.integrated.defaultProfile.windows": "Custom Init"
}
```
You can use variables in terminal profiles as shown in the example above
with the `APPDATA` environment variable. There is a list of
available variables in the{' '}
Variables Reference topic.
Configure your default profile by running the{' '}
Terminal: Select Default Profile command, which is also
accessible via the new terminal dropdown.
The default terminal profile shell defaults to `$SHELL` on
Linux and macOS and PowerShell on Windows. AVAP TM Dev Studio
will automatically detect most standard shells that can then be configured
as the default.
## Configuring profiles
To create a new profile, run the{' '}
Terminal: Select Default Profile command and activate the
configure button on the right side of the shell to base it on. This will
add a new entry to your settings that can be tweaked manually in your{' '}
`settings.json` file.
Profiles can be created using either a `path` or a{' '}
`source` , as well as a set of optional arguments. A{' '}
`source` is available only on Windows and can be used to let
AVAP TM Dev Studio detect the install of either{' '}
`PowerShell` or `Git Bash` . Alternatively, a{' '}
`path` pointing directly to the shell executable can be used.
Here are some example profile configurations:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"PowerShell -NoProfile": {
` `"source": "PowerShell",
` `"args": ["-NoProfile"]
` `}
` `},
` `"terminal.integrated.profiles.linux": {
` `"zsh (login)": {
` `"path": "zsh",
` `"args": ["-l"]
` `}
` `}
}
```
Other arguments supported in profiles include:
* `overrideName` : A boolean indicating whether or not to replace the dynamic terminal title that detects what program is running with the static profile name.
* `env` : A map defining environment variables and their values, set the variable to null to delete it from the environment. This can be configured for all profiles using the{' '} `terminal.integrated.env.<platform>` setting.
* `icon` : An icon ID to use for the profile.
* `color` : A theme color ID to style the icon.
The default profile can be defined manually with the{' '}
`terminal.integrated.defaultProfile.\*` settings. This should
be set to the name of an existing profile:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"my-pwsh": {
` `"source": "PowerShell",
` `"args": ["-NoProfile"]
` `}
` `},
` `"terminal.integrated.defaultProfile.windows": "my-pwsh"
}
```
## Removing built-in profiles
To remove a built-in profile and prevent it from showing up in the new
terminal dropdown, set the name of the profile to `null` . For
example, to remove the `Git Bash` profile on Windows, use this
setting:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"Git Bash": null
` `}
}
```
## Configuring the task/debug profile
By default, the task/debug features will use the default profile. This may
not be ideal if your default has a heavy PowerShell startup script or a
non-POSIX compliant shell for example. To configure a profile to be used
only in the debug/tasks features, use the{' '}
`terminal.integrated.automationProfile` .
`<platform>` setting:
```javascript
{
` `"terminal.integrated.defaultProfile.osx": "fish",
` `// Use a fully POSIX-compatible shell and avoid running a
complex ~/.config/fish/config.fish
` `// for tasks and debug
` `"terminal.integrated.automationProfile.osx": {
` `"path": "/bin/sh"
` `}
}
```
## Unsafe profile detection
Certain shells are installed in unsafe paths by default, like a path that
could be written to by another user on a Windows environment. AVAP
TM Dev Studio will still detect these but not expose them as a
proper profile until they have been explicitly configured via the{' '}
Terminal: Select Default Profile command. When
configuring an unsafe profile, there will be a warning before it's
added:
## Cmder
Cmder itself is a terminal, but you can use the [Cmder] shell in AVAP
TM Dev Studio with the following profile:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"cmder": {
` `"path": "C:\\WINDOWS\\System32\\cmd.exe",
` `"args": ["/K", "C:\\cmder\\vendor\\bin\\vscode\_init.cmd"]
` `}
` `},
` `"terminal.integrated.defaultProfile.windows": "cmder"
}
```
This profile should be picked up automatically when the{' '}
`CMDER\_ROOT` environment variable is set. It will also be
detected as an unsafe profile if installed at `C:\cmder` . You
may refer to Cmder's wiki for more information.
## Cygwin
Cygwin itself is a terminal, but you can use the Cygwin shell in AVAP
TM Dev Studio with the following profile:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"Cygwin": {
` `"path": "C:\\cygwin64\\bin\\bash.exe",
` `"args": ["--login"]
` `}
` `},
` `"terminal.integrated.defaultProfile.windows": "Cygwin"
}
```
This profile should be detected automatically as an unsafe profile when
installed at the default paths `C:\cygwin` or
`C:\cygwin64` .
## Git Bash
A limitation of Git Bash when AVAP TM Dev Studio uses bash.exe
(the shell) as opposed to git-bash.exe (the terminal) is
that history will not be retained across shell sessions. You can work
around this by adding the following to your `~/.bashrc` a or{' '}
`~/.bash\_profile` files:
```javascript
export PROMPT\_COMMAND='history -a'
```
This will cause the shell to call history -a whenever the prompt is
printed which flushes the session's current session commands to the
backing history file.
## MSYS2
MSYS2's bash shell can be configured with the following profile:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"bash (MSYS2)": {
` `"path": "C:\\msys64\\usr\\bin\\bash.exe",
` `"args": ["--login", "-i"],
` `"env": { "CHERE\_INVOKING": "1" }
` `}
` `}
}
```
The `CHERE_INVOKING` environment variable is used to tell the
login initialization script to preserve the working directory, instead of
opening at `$HOME` .
This profile should be detected automatically as an{' '}
unsafe profile when installed at
the default path `C:\\msys64` .
## Windows PowerShell
When PowerShell 6+ is installed, Windows PowerShell is not included in the
profiles list by default. To add Windows PowerShell as a profile, choose
the Select Default Profile option in the new terminal
dropdown and select the Windows PowerShell item. This will configure the
profile and set it as your default.
## WSL
When running AVAP TM Dev Studio on your local machine, Windows
Subsystem for Linux shells should be automatically detected. Depending on
your setup, this may be a nuisance if you have a lot of distros installed.
For finer control over the WSL profiles the automatic detection can be
disabled with the `terminal.integrated.useWslProfiles setting` ,
then here's an example of how to manually configure a WSL shell:
```javascript
{
` `"terminal.integrated.profiles.windows": {
` `"Debian (WSL)": {
` `"path": "C:\\WINDOWS\\System32\\wsl.exe",
` `"args": [` `"-d",
` `"Debian"
` `]
` `}
` `}
}
```
## Common questions
### Why are there duplicate paths in the terminal's $PATH environment
variable and/or why are they reversed on macOS?
This can happen on macOS because of how the terminal launches using AVAP
TM Dev Studio's environment. When AVAP TM Dev
Studio launches for the first time, to source your "development
environment," it launches your configured shell as a{' '}
login shell , which runs your{' '}
`~/.profile/~/.bash\_profile/~/.zprofile` scripts. Now when the
terminal launches, it also runs as a login shell, which will put the
standard paths to the front (for example,{' '}
`/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin` ) and
reinitialize your shell environment.
To get a better understanding, you can simulate what is happening by
launching an inner login shell within your operating system's built-in
terminal:
```javascript
\# Add /test to the beginning of $PATH
export PATH=/test:$PATH
\# Echo $PATH, /test should be at the beginning
echo $PATH
\# Run bash as a login shell
bash -l
\# Echo $PATH, the values should be jumbled
echo $PATH
```
Unfortunately, unlike in Linux, standalone macOS terminals all run as
login shells by default, since macOS does not run a login shell when the
user logs into the system. This encourages "bad behavior," like
initializing aliases in your profile script when they should live in your{' '}
`rc` script as that runs on non-login shells.
There are two direct fixes for this. The first is to set{' '}
`"terminal.integrated.inheritEnv": false` , which will
strip most environment variables from the terminal's environment,
except for some important ones (like `HOME` ,{' '}
`SHELL` , `TMPDIR` , etc.).
The other fix is to no longer run a login shell in the terminal by
creating a terminal profile and setting its args to []. If you go with
this fix, you will want to make sure any aliases in your profile scripts
are moved over to your `~/.bashrc/~/.zshrc` file since aliases
only apply to the shell they're set in.
