Many times we look at the data in the database, or the data in other people's systems need to be time-stamped to query, or the result of the query is a timestamp. There are times when you need to enter a timestamp for the query condition. My previous approach is to use the online tool to complete, and later with the Mac, I think directly with the command line to solve the good, do not have to open a browser

In Linux systems, there are many occasions when a timestamp is used to represent the time, from January 1, 1970 to the current number of days or seconds. such as the/etc/shadow Password change date and expiration date, as well as the proxy server's access log to the access time records, and so on. Several timestamp formats and standard time

In Linux systems, there are many occasions where timestamps are used to represent time, that is, the number of days or seconds from January 1, 1970 onwards. such as the password change date and expiration date in/etc/shadow, as well as the access log of the proxy server to record the access time and so on.Here are some methods of timestamp format and standard Tim

Everyone knows that every file in the Linux file system has three timestamps:Access time (atime--access time): Is the date the file was last accessed.Change Time (Ctime--change): Is the time of the file's inode change (what is the inode?). When you add data or delete data to a file, when you change the file owner, the CTime of the file changes when the link changes.Modified (mtime--modification time): Is the time when the content of the file was last

The Dos2unix command is used to convert a DOS-formatted text file into Unix (Dos/mac to UNIX text, format Converter). Dos text file is based on \ r \ n As a break mark, expressed as 16 binary is 0D 0 A. The text file under Unix is marked with \ n as a break mark, which means that the 16 binary is 0 a. The DOS format text file under Linux, with the lower version o

following:Figure 9 TCP Connection Second handshake instance Why is MSS 1452 instead of 1460?This is due to the use of PPPoE (point-to-point over Ethernet. Enables the Ethernet host to connect to an unwarranted access concentrator via a simple bridging device [3]) dial-up internet access. The Ppop header is 8 bytes, so the MTU of PPPoE is 1492,MSS and 1492-40=1452. So, what is the MSS that transmits data after the TCP connection is established, 1460 or 1452 or 536? My understanding is the defaul
