paragrep searches for a series of regular expressions in a text file (or several text files) and prints out the paragraphs containing those expressions. Normally paragrep displays a paragraph if it contains any of the expressions; this behavior can be modified by using the -a option.By default, a paragraph is defined as a block of text delimited by an empty or blank line; this behavior can be altered with the -p option. If no files are specified on the command line, paragrep searches standard input.NOTE: paragrep is licensed and distributed under the terms of the BSD License.
