isWritable

isWritable( 
S_name 
[ tl_path ] 
) 
=> t / nil

Description

Checks if you have permission to write to a file or update a directory. Uses the current SKILL path for relative paths. A path that is anchored to the current directory, for example, ./, ../, or ../../.., and so on, is not considered as a relative path.

Arguments

S_name	Name of a file or directory you want to find out your write permission on.
tl_path	List of paths to search that overrides the SKILL path.

Value Returned

t	If S_name exists and you have permission to write or update it.
nil	The file does not exist or does exist, but you do not have permission to read it.

Examples

isWritable("/tmp")
=> t 

Result if out.1 does not exist or there is no write permission to it.

isWritable("~/test/out.1") 
=> nil
