File::Constants
File::Constants provides file-related constants. All possible file constants are listed in the documentation but they may not all be present on your platform.
If the underlying platform doesn't define a constant the corresponding Ruby constant is not defined.
Your platform documentations (e.g. man open(2)) may describe more detailed information.
Constants
- APPEND
append on each write
- BINARY
disable line code conversion
- CREAT
create file if it does not exist
- DIRECT
Try to minimize cache effects of the I/O to and from this file.
- DSYNC
any write operation perform synchronously except some meta data
- EXCL
error if CREAT and the file exists
- FNM_CASEFOLD
Makes File.fnmatch patterns case insensitive (but not Dir.glob patterns).
- FNM_DOTMATCH
The '*' wildcard matches filenames starting with “.” in File.fnmatch and Dir.glob patterns
- FNM_EXTGLOB
Allows file globbing through “{a,b}” in File.fnmatch patterns.
- FNM_NOESCAPE
Disables escapes in File.fnmatch and Dir.glob patterns
- FNM_PATHNAME
Wildcards in File.fnmatch and Dir.glob patterns do not match directory separators
- FNM_SHORTNAME
Makes patterns to match short names if existing. Valid only on Microsoft Windows.
- FNM_SYSCASE
System default case insensitiveness, equals to FNM_CASEFOLD or 0.
