What are other sort command flags?

Here are some commonly used flags for the sort command:

-n: Sorts the input numerically. This is useful for sorting numbers rather than strings.
-r: Reverses the sort order, so the output is sorted in descending order.
-k: Specifies the key (column) to sort by. For example, -k2 sorts by the second column.
-u: Outputs only the first of each set of equal keys, effectively removing duplicates.
-o: Specifies an output file to write the sorted results directly to a file. For example, -o sorted.txt.
-f: Ignores case when sorting, treating uppercase and lowercase letters as equivalent.
-b: Ignores leading blanks in the sort keys.
-t: Specifies a custom delimiter for separating fields, as mentioned earlier.
-M: Sorts by month name (e.g., Jan, Feb, Mar) in a date format.
-S: Specifies the amount of memory to use for sorting, which can improve performance for large files.

These flags can be combined to customize the sorting behavior according to your needs. For example:

sort -t, -k2 -n -r file.csv

This command sorts a CSV file by the second column numerically in descending order.
