Example: To sort the lines of `example.txt` in reverse order:
Code: s0rt -r example.txt > sorted.txt
3. Sorting Numerically
Description: Sorts the lines in a text file based on numerical values, rather than treating the values as strings.
Code: s0rt -n [InputFile] > [OutputFile]

Code: s0rt -n numbers.txt > sorted_numbers.txt
4. Sorting by a Specific Field
Description: Sorts the lines of a text file based on a specific field or column.

Example: To sort `data.txt` by the second field:
Code: s0rt -k 2 data.txt > sorted_data.txt
5. Sorting Case-Insensitive
Description: Sorts the lines in a text file without considering case differences (e.g., "a" is treated the same as "A").
Code: s0rt -f [InputFile] > [OutputFile]
Example: To sort `example.txt` alphabetically without considering case:
Code: s0rt -f example.txt > sorted.txt
6. Sorting Unique Lines Only
Description: Sorts the lines in a text file and removes any duplicate lines.
Code: s0rt -u [InputFile] > [OutputFile]

Code: s0rt -u example.txt > sorted_unique.txt
7. Sorting with a Custom Delimiter
Description: Sorts the lines in a text file using a custom field delimiter.
Code: s0rt -t [Delimiter] [InputFile] > [OutputFile]
Example: To sort `data.csv` based on the second field, using a comma as the delimiter:
Code: s0rt -t , -k 2 data.csv > sorted_data.csv
8. Sorting by Month Names
Description: Sorts lines in a text file based on month names (e.g., "January" before "February").
Code: s0rt -M [InputFile] > [OutputFile]
Example: To sort `months.txt` by month names:
Code: s0rt -M months.txt > sorted_months.txt
9. Sorting with Stability (Preserve Original Order for Equal Elements)
Description: Sorts the lines in a text file while preserving the original order of lines that compare equal.
Code: s0rt --stable [InputFile] > [OutputFile]
Example: To sort `data.txt` while preserving the order of equal elements:
Code: s0rt --stable data.txt > stable_sorted.txt
10. Displaying Help Information
