New page

In [[Mini Micro]] and [[command-line MiniScript]], the <c>[[file]].exists</c> function checks if a file or directory exists at the specified path.

=== Arguments ===

{| class="wikitable"
|-
! Parameter Name !! Meaning
|-
| filePath|| an absolute or relative path of the file or directory to be tested.
|}

{| class="wikitable"
|-
! Return !! Meaning
|-
| 1 ''(true)'' || The file or directory exists.
|-
| 0 ''(false)'' || The file or directory does not exist.
|}

== Example ==

Test the existence of various files and directories:

<ms>if file.exists("/usr2") then print "/usr2 appears to be mounted!"
if file.exists("/usr2/myapp.ms") then print "myapp.ms is there!"

// Look for a file in the parent directory of the current working directory.
if not file.exists("../output.txt") then
file.writeLines "../output.txt", "This file will be created with this string at the top. Woot!"
else
file.writeLines "../output.txt", "This file will be overwritten with a BETTER string at the top."
end if
</ms>
