the file exists but that path to access it is too long.

the file exists but you don't have search permission to the parent directory.

the file exists but is not a regular file (could be a device, fifo, directory, socket.).

However if it returns false (or if or ! return true), there are many different possibilities: So if returns true, you can tell the file does exist and is a regular file or a symlink eventually resolving to a regular file (or at least it was at the time of the stat()). The [ command does a stat() (not lstat()) system call on the path stored in $file and returns true if that system call succeeds and the type of the file as returned by stat() is ' regular'. x filename - Check if file is executableĪ test expression can be negated by using the ! operator #!/bin/bash

u filename - Check if file set-user-id bit is set s filename - Check if file is nonzero size r filename - Check if file is a readable O filename - True if file exists and is owned by the effective user id G filename set-group-id - True if file exists and is set-group-id G filename - Check if file exists and is owned by effective group ID f filename - Check for regular file existence not a directory e filename - Check for file existence, regardless of type (node, directory, socket, etc.)

d directoryname - Check for directory Existence
