Find string multiple times, same line
Hi everybody,

Fairly simple question here:

I need an awk, sed, or grep command that will find the same string multiple times on one line

needs to return all lines which contain .02 twice.

I do know the exact number of characters in between the two occurrences of .02 if that helps, all such lines are --------.02------.02------ with exactly six characters in between, but an indefinite amount of characters before and after.

Thank you

look

LOOK(1) 						    BSD General Commands Manual 						   LOOK(1)

NAME

     look -- display lines beginning with a given string

SYNOPSIS

     look [-df] [-t termchar] string [file ...]

DESCRIPTION

     The look utility displays any lines in file which contain string as a prefix.  As look performs a binary search, the lines in file must be
     sorted.

     If file is not specified, the file /usr/share/dict/words is used, only alphanumeric characters are compared and the case of alphabetic char-
     acters is ignored.

     Options:

     -d      Dictionary character set and order, i.e. only alphanumeric characters are compared.

     -f      Ignore the case of alphabetic characters.

     -t      Specify a string termination character, i.e. only the characters in string up to and including the first occurrence of termchar are
	     compared.

     The look utility exits 0 if one or more lines were found and displayed, 1 if no lines were found, and >1 if an error occurred.

FILES

     /usr/share/dict/words  the dictionary

SEE ALSO

     grep(1), sort(1)

COMPATIBILITY

     The original manual page stated that tabs and blank characters participated in comparisons when the -d option was specified.  This was incor-
     rect and the current man page matches the historic implementation.

HISTORY

     A look utility appeared in Version 7 AT&T UNIX.
