The -t flag in the sort command specifies a delimiter that separates fields in the input data. By default, sort uses whitespace as the delimiter, but with the -t option, you can define a custom delimiter.
For example, if you have a colon-separated file and you want to sort based on the second field, you would use:
sort -t: -k2 filename.txt
In this command:
-t:sets the delimiter to a colon (:).-k2indicates that sorting should be based on the second field.
This is useful for sorting structured data where fields are separated by specific characters.
