# Running Psalm
|
||
|
||
Once you've set up your config file, you can run Psalm from your project's root directory with
|
||
```bash
|
||
./vendor/bin/psalm
|
||
```
|
||
|
||
and Psalm will scan all files in the project referenced by `<projectFiles>`.
|
||
|
||
If you want to run on specific files, use
|
||
```bash
|
||
./vendor/bin/psalm file1.php [file2.php...]
|
||
```
|
||
|
||
## Command-line options
|
||
|
||
Run with `--help` to see a list of options that Psalm supports.
|
||
|
||
## Exit status
|
||
|
||
Psalm exits with status `0` when it successfully completed and found no issues,
|
||
`1` when there was a problem running Psalm and `2` when it completed
|
||
successfully but found some issues. Any exit status apart from those indicate
|
||
some internal problem.
|
||
|
||
## Shepherd
|
||
|
||
Psalm currently offers some GitHub integration with public projects.
|
||
|
||
Add `--shepherd` to send information about your build to https://shepherd.dev.
|
||
|
||
Currently, Shepherd tracks type coverage (the percentage of types Psalm can infer) on `master` branches.
|
||
|
||
## Running Psalm faster
|
||
|
||
Psalm has a couple of command-line options that will result in faster builds:
|
||
|
||
- `--threads=[n]` to run Psalm’s analysis in a number of threads
|
||
- `--diff` which only checks files you’ve updated since the last run (and their dependents).
|
||
|
||
In Psalm 4 `--diff` is turned on by default (you can disable it with `--no-diff`).
|
||
|
||
Data from the last run is stored in the *cache directory*, which may be set in [configuration](./configuration.md).
|
||
If you are running Psalm on a build server, you may want to configure the server to ensure that the cache directory
|
||
is preserved between runs.
|
||
|
||
Running them together (e.g. `--threads=8 --diff`) will result in the fastest possible Psalm run.
