Sort file contents in dos

SORT command is used to sort a file, arranging the records in a particular order. Using options in the sort command can also be used to sort numerically. SORT command sorts the contents of a text file, line by line. The sort command is a command-line utility for sorting lines of text files. It supports sorting alphabetically, in reverse order, by number, by month, and can also remove duplicates.

The sort command can also sort by items not at the beginning of the line, ignore case sensitivity, and return whether a file is sorted or not. Sorting is done based on one or more sort keys extracted from each line of input. By default, the entire input is taken as the sort key. Blank space is the default field separator. The sort command follows these features as stated below: Lines starting with a number will appear before lines starting with a letter.

Lines starting with a letter that appears earlier in the alphabet will appear before lines starting with a letter that appears later in the alphabet. Lines starting with a lowercase letter will appear before lines starting with the same letter in uppercase. Examples Suppose you create a data file with name file. Sort function with mix file i. Example: Create a file mix. Be default, sort command uses only KB of space to store the file contents in main memory. Increasing this limit, will increase the performance of the sort operation.

To let the sort command use 10MB of memory, we can run the below command. The memory size is always constrained to be a minimum of kilobytes. If the memory size is specified the exact amount will be used for the sort, regardless of how much main memory is available. The best performance is usually achieved by not specifying a memory size. Finally, we reopen our text file for writing this time and use the WriteLine method to replace the existing contents with the value of strText.
