5 Examples of df command in Linux

The df command is used to find the amount of disk space used and available on different partitions and file systems. The simplest example of df command is just typing df on console with out any arguments and it will show you the space used and available on all currently mounted file systems of all types e.g NFS, ext3 and both local and remote. Alternatively you can ask df command to print the size and space available and used for a particular partition. Normally the disk space is printed in units of 1024 bytes, but this can be overridden. I commonly use df -h option to print the size and disk usage in human readable format e.g. G for giga bytes, M for mega bytes and so on.

Why use Date as YYYYMMDD in SQL Server?

When you enter a Date in SQL SERVER for inserting data or filtering data in WHERE clause, what you enter is String. SQL Server infernally converts that formatted String to different date and time data types in Java e.g. DATETIME, DATE, TIME, DATETIME2 and SMALLDATETIME. This conversion is subject to language setting in SQL SERVER, for example, the same date 03/07/2015 can be interpreted as 3rd March 2015 if language setting is US English (MMDDYYYY) and 3rd July 2015 if language is set to British English(DDMMYYYY). To avoid this, you can enter date as YYYYMMDD format, which is considered language neutral and always interpreted correctly by Microsoft SQL Server.
