Top Forums Shell Programming and Scripting Awk, sed - concatenate lines starting with string Post 302759705 by Don Cragun on Tuesday 22nd of January 2013 07:46:37 PM

The following seems to do what you want:
Code:
awk '! /^http/ {
        if(nnl) printf("\n")
        nnl = 1
        printf("%s", $0)
        next
}
{       printf(";%s", $0)
}
END {   if(nnl) printf("\n")
}' input

Note that this will work with both http: and https: sites, but won't do the right thing if someone's name starts with http.

TM::Literal(3pm)					User Contributed Perl Documentation					  TM::Literal(3pm)

NAME
TM::Literal - Topic Maps, simple values (literals) SYNOPSIS use TM::Literal; my $l = new TM::Literal (42, 'xsd:integer'); print $l->[0]; # prints 42 print $l->[1]; # prints http://www.w3.org/2001/XMLSchema#integer $l = new TM::Literal(42); # default is xsd:string DESCRIPTION
This packages will eventually handle all literal handling, i.e. not only a way to create and retrieve information about simple values used inside topic maps, but also all necessary operations such as integer addition, string manipulation. This is quite a chore, especially since the data types adopted here are the XML Schema Data Types. Constants XSD http://www.w3.org/2001/XMLSchema# INTEGER http://www.w3.org/2001/XMLSchema#integer DECIMAL http://www.w3.org/2001/XMLSchema#decimal FLOAT http://www.w3.org/2001/XMLSchema#float DOUBLE http://www.w3.org/2001/XMLSchema#double STRING http://www.w3.org/2001/XMLSchema#string URI http://www.w3.org/2001/XMLSchema#anyURI ANY http://www.w3.org/2001/XMLSchema#anyType Grammar TODO Operations TODO SEE ALSO
