Method: File.expand_path
- Defined in:
- file.c
.expand_path(file_name[, dir_string]) ⇒ Object
Converts a pathname to an absolute pathname. Relative paths are referenced from the current working directory of the process unless dir_string is given, in which case it will be used as the starting point. The given pathname may start with a "~
", which expands to the process owner's home directory (the environment variable HOME
must be set correctly). "~
user" expands to the named user's home directory.
File.expand_path("~oracle/bin") #=> "/home/oracle/bin"
File.expand_path("../../bin", "/tmp/x") #=> "/bin"
