sort -- Sorting Text

The sort tool can be used to sort text. It sorts the contents of the files named on the commandline, or the text provided on standard input if no files are given. Output is to standard output by default, unless a -o filename option is provided.

To ignore case, the -f switch may be used.

Many other options are available. See man sort and IEEE1003.1-2004-sort for details.
