Returns a File::Stat object for the named file (see File::Stat).
File.stat("testfile").mtime #=> Tue Apr 08 12:58:04 CDT 2003
Same as File::stat, but does not follow the last symbolic link. Instead, reports on the link itself.
File.symlink("testfile", "link2test") #=> 0 File.stat("testfile").size #=> 66 File.lstat("link2test").size #=> 8 File.stat("link2test").size #=> 66
Same as IO#stat, but does not follow the last symbolic link. Instead, reports on the link itself.
File.symlink("testfile", "link2test") #=> 0 File.stat("testfile").size #=> 66 f = File.new("link2test") f.lstat.size #=> 8 f.stat.size #=> 66
Return the status value associated with this system exit.
Returns a hash of parsed elements.
Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.
Creates a new Date object by parsing from a string according to some RFC 2616 format.
Date.httpdate('Sat, 03 Feb 2001 00:00:00 GMT') #=> #<Date: 2001-02-03 ...>
Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.
Returns true if the date is Saturday.
This method is equivalent to strftime(‘%a, %d %b %Y %T GMT’). See also RFC 2616.
Creates a new DateTime object by parsing from a string according to some RFC 2616 format.
DateTime.httpdate('Sat, 03 Feb 2001 04:05:06 GMT') #=> #<DateTime: 2001-02-03T04:05:06+00:00 ...>
Raise an ArgumentError when the string length is longer than limit. You can stop this check by passing ‘limit: nil`, but note that it may take a long time to parse.
Parses date as an HTTP-date defined by RFC 2616 and converts it to a Time object.
ArgumentError is raised if date is not compliant with RFC 2616 or if the Time class cannot represent specified date.
See httpdate for more information on this format.
require 'time' Time.httpdate("Thu, 06 Oct 2011 02:26:12 GMT") #=> 2011-10-06 02:26:12 UTC
You must require ‘time’ to use this method.
Returns a string which represents the time as RFC 1123 date of HTTP-date defined by RFC 2616:
day-of-week, DD month-name CCYY hh:mm:ss GMT
Note that the result is always UTC (GMT).
require 'time' t = Time.now t.httpdate # => "Thu, 06 Oct 2011 02:26:12 GMT"
You must require ‘time’ to use this method.
Returns true if time represents Saturday.
t = Time.local(2006, 6, 10) #=> 2006-06-10 00:00:00 -0500 t.saturday? #=> true
Updates the database with multiple values from the specified object. Takes any object which implements the each_pair method, including Hash and DBM objects.
Returns status information for ios as an object of type File::Stat.
f = File.new("testfile") s = f.stat "%o" % s.mode #=> "100644" s.blksize #=> 4096 s.atime #=> Wed Apr 09 08:53:54 CDT 2003
Adds the key-value pairs of other to gdbm, overwriting entries with duplicate keys with those from other. other must have an each_pair method.
See File.lstat.
Return scanner state of current token.
Insert or update key-value pairs.
This method will work with any object which implements an each_pair method, such as a Hash.
Adds the contents of the given hashes to the receiver.
If no block is given, entries with duplicate keys are overwritten with the values from each other_hash successively, otherwise the value for each duplicate key is determined by calling the block with the key, its value in the receiver and its value in each other_hash.
h1 = { "a" => 100, "b" => 200 } h1.merge! #=> {"a"=>100, "b"=>200} h1 #=> {"a"=>100, "b"=>200} h1 = { "a" => 100, "b" => 200 } h2 = { "b" => 246, "c" => 300 } h1.merge!(h2) #=> {"a"=>100, "b"=>246, "c"=>300} h1 #=> {"a"=>100, "b"=>246, "c"=>300} h1 = { "a" => 100, "b" => 200 } h2 = { "b" => 246, "c" => 300 } h3 = { "b" => 357, "d" => 400 } h1.merge!(h2, h3) #=> {"a"=>100, "b"=>357, "c"=>300, "d"=>400} h1 #=> {"a"=>100, "b"=>357, "c"=>300, "d"=>400} h1 = { "a" => 100, "b" => 200 } h2 = { "b" => 246, "c" => 300 } h3 = { "b" => 357, "d" => 400 } h1.merge!(h2, h3) {|key, v1, v2| v1 } #=> {"a"=>100, "b"=>200, "c"=>300, "d"=>400} h1 #=> {"a"=>100, "b"=>200, "c"=>300, "d"=>400}
Hash#update is an alias for Hash#merge!.
Adds the contents of hash to the environment variables. If no block is specified entries with duplicate keys are overwritten, otherwise the value of each duplicate name is determined by calling the block with the key, its value from the environment and its value from the hash.
Returns true iff the current severity level allows for the printing of FATAL messages.
Sets the severity to FATAL.
