developers the freedom to define how locks are acquired and how locks are freed. Sync is the internal abstraction class of Reentrantlock, which implements a simple acquisition lock and a release lock. Nonfairsync and Fairsync respectively represent "unjust locks" and "fair locks", both of which inherit from sync and are all internal classes of reentrantlock. Reentrantlock implements the Lock-unlock method of the lock interface and determines whether to use Nonfairsync or Fairsync according to t

The principle is to obtain the current ip address based on the IP Address Provided by the user and convert it to a digital IP address. The calculation is based on the ip address, a, B, and c, according to the comparison, the "OK" principle is based on the ip address given by the user, and then the current IP address is obtained and converted to a numeric type. The calculation is based on the IP address, a, B, and c.

In Linux, how does one use shell scripts to capture remote logs? There is a dilemma in analyzing online logs. There are too many machines. It is unrealistic to log on to each server, but it is more troublesome to download the logs because each SCP requires a password. So I wrote a script to automatically capture remote logs to implement basic functions.

If {$ argc! = 1 $ argc! = 2 }{Send_user "no remote log file name entered. \ n"Send_user "Format: Get. Sh $ {remote_log }
