REX Program Syntax and Options

REX locates and prints lines containing occurrences of regular expressions. Beginning and end of line are the default beginning and ending delimiters. If starting (-s) and ending (-e) delimiters are specified REX will print from the beginning delimiting expression to the ending delimiting expression. If so specified (-p) REX will print the expression only. If files are not specified, standard input is used. If files are specified, the filename will be printed before the line containing the expression, unless the "-n" option (don't print the filename) is used.
