Here trying to match from a line with pattern /\/\*--* $str --*\*\// to another line with the pattern /^ *$/.If you want to specify two address then you have to separate it with comma.

/^ *$/
* matches any number or none of the single character that immediately precedes it.So this will match empty line as well as lines with blanks.
thanks anbu

this funda i hadnt come across in the 2 months that i hv been learning unix. i thought only sed '1,3 p' works. didnt know patterns can also be matched the same way.
