iswritable
iswritable(path) -> Bool
Returns true if the current user has permission to write to path, false otherwise.
Examples
Check if a file is writable:
julia> iswritable("path/to/file.txt")
trueThis example checks if the current user has permission to write to the file specified by the path "path/to/file.txt". If the user has write permission, it returns true.
julia> iswritable("/etc/passwd")
falseIn this example, the function returns false because the current user does not have write permission for the file /etc/passwd.
Handle non-existent paths:
julia> iswritable("nonexistent/file.txt")
falseWhen the specified file or directory does not exist, iswritable returns false. It does not create the file or directory, only checks for write permission.
Common mistake example:
julia> iswritable("/root/file.txt")
ERROR: SystemError: Permission deniedIn this example, the function throws an error because the current user does not have permission to access the file /root/file.txt. It's important to ensure that the user has the necessary permissions before calling iswritable to avoid such errors.
