Re: remove specific data from a line

[idle]

So you wanna remove the string if it start with myword? Try this:

if $line =~ /^myword.*$/ {
     $line =~ s/$&//g
    }

Updated. Oh I see you need to remove the line until the last option. Heres the code:

if $line =~ /(^myword.*option\d+\s+).*$/ {
     $line =~ s/$1//g
    }

I not explain too good sorry. Let me try eloborate. String could look like this

abc123 qwerty,asdfg,zxcvb yuio jklh

or like this

abc987 qwerty yuio jklh

or this

abcefgh qwerty, asdfg yuio jklh

So I want to end up with same string from all examples above. It should end up like this


yuio jklh

Hope this make it bit clearer, sorry for confuse my english not so good

[graff]

Given those examples, there might be a few ways to do this -- either try to match from the start of the string:

s/abc\w+\s+\w+(?:, *\w+)\s+//;  # match and remove unwanted initial co
+ntent

or else just look for what you want to keep at the end:

s/.*\s(\w+\s+\w+)$/$1/;  # match desired end content and remove everyt
+hing before it

And of course, if you know in advance how those last two tokens are spelled, you could even use rindex() and substr():

$_ = substr( $_, rindex( $_, 'yuio jklh' ));

Thank for answer but not quite what I look for. This  s/abc\w+\s+\w+(?:, *\w+)\s+//; only work correct on last line of my example.
I'm not able to use second or third option you supply because I do not know what end of line hold only what beginning of line look like. See my reponse to Roy Johnson. Thanks
