# `fileexists` Function
|
|
|
|
`fileexists` determines whether a file exists at a given path.
|
|
|
|
```hcl
|
|
fileexists(path)
|
|
```
|
|
|
|
Functions are evaluated during configuration parsing rather than at apply time,
|
|
so this function can only be used with files that are already present on disk
|
|
before Terraform takes any actions.
|
|
|
|
This function works only with regular files. If used with a directory, FIFO,
|
|
or other special mode, it will return an error.
|
|
|
|
## Examples
|
|
|
|
```
|
|
> fileexists("${path.module}/hello.txt")
|
|
true
|
|
```
|
|
|
|
```hcl
|
|
fileexists("custom-section.sh") ? file("custom-section.sh") : local.default_content
|
|
```
|
