Change owner and group of the file.

See File.chown.

Same as Pathname.chown, but does not follow symbolic links.

See File.lchown.

Returns a File::Stat object.

See File.stat.

See File.lstat.

Truncates the file to length bytes.

See File.truncate.

See FileTest.chardev?.

Return scanner state of current token.

Iterates over each key-value pair in the database.

If no block is given, returns an Enumerator.

Insert or update key-value pairs.

This method will work with any object which implements an each_pair method, such as a Hash.

creates a new socket object connected to host:port using TCP/IP.

If local_host:local_port is given, the socket is bound to it.

The optional last argument opts is options represented by a hash. opts may have following options:

:connect_timeout

specify the timeout in seconds.

:resolv_timeout

specify the name resolution timeout in seconds.

If a block is given, the block is called with the socket. The value of the block is returned. The socket is closed when this method returns.

If no block is given, the socket is returned.

Socket.tcp("www.ruby-lang.org", 80) {|sock|
  sock.print "GET / HTTP/1.0\r\nHost: www.ruby-lang.org\r\n\r\n"
  sock.close_write
  puts sock.read
}

iterates over the list of Addrinfo objects obtained by Addrinfo.getaddrinfo.

Addrinfo.foreach(nil, 80) {|x| p x }
#=> #<Addrinfo: 127.0.0.1:80 TCP (:80)>
#   #<Addrinfo: 127.0.0.1:80 UDP (:80)>
#   #<Addrinfo: [::1]:80 TCP (:80)>
#   #<Addrinfo: [::1]:80 UDP (:80)>

returns an addrinfo object for TCP address.

Addrinfo.tcp("localhost", "smtp") #=> #<Addrinfo: 127.0.0.1:25 TCP (localhost:smtp)>

Returns the path of the local address of unixsocket.

s = UNIXServer.new("/tmp/sock")
p s.path #=> "/tmp/sock"

Puts stream into binary mode. See IO#binmode.

See IO#each.

This is a deprecated alias for each_char.

See IO#getc.

Pushes back one character (passed as a parameter) such that a subsequent buffered read will return it. There is no limitation for multiple pushbacks including pushing back behind the beginning of the buffer string.

See IO#putc.

Returns false. Just for compatibility to IO.

Truncates the buffer string to at most integer bytes. The stream must be opened for writing.

Sets the scan pointer to the end of the string and clear matching data.

Appends str to the string being scanned. This method does not affect scan pointer.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.scan(/Fri /)
s << " +1000 GMT"
s.string            # -> "Fri Dec 12 1975 14:39 +1000 GMT"
s.scan(/Dec/)       # -> "Dec"

Returns the character position of the scan pointer. In the ‘reset’ position, this value is zero. In the ‘terminated’ position (i.e. the string is exhausted), this value is the size of the string.

In short, it’s a 0-based index into the string.

s = StringScanner.new("abcädeföghi")
s.charpos           # -> 0
s.scan_until(/ä/)   # -> "abcä"
s.pos               # -> 5
s.charpos           # -> 4

This returns the value that scan would return, without advancing the scan pointer. The match register is affected, though.

s = StringScanner.new("Fri Dec 12 1975 14:39")
s.check /Fri/               # -> "Fri"
s.pos                       # -> 0
s.matched                   # -> "Fri"
s.check /12/                # -> nil
s.matched                   # -> nil

Mnemonic: it “checks” to see whether a scan will return a value.
