i new at this so hav been tryin everythin i can find by googling the problem
#sed 's/ //g' oldfile > newfile
#sed '$s/ \+//g' oldfile > newfile
and quite a few others similar to this.
one thing that did seem strange is if i do the first one i mentioned it will do the top line i.e www1=www1 but all the rest of the lines remain the same but if i again do the first one i mentioned but do
#sed 's/www/hello/g' oldfile > newfile
it successfully changes all the www's to hello.
In my books thats strange but like i said im a newbie
Thanks for your swift response

libnetcfg
LIBNETCFG(1) Perl Programmers Reference Guide LIBNETCFG(1) NAME
libnetcfg - configure libnet DESCRIPTION
The libnetcfg utility can be used to configure the libnet. Starting from perl 5.8 libnet is part of the standard Perl distribution, but the libnetcfg can be used for any libnet installation. USAGE
Without arguments libnetcfg displays the current configuration. $ libnetcfg # old config ./libnet.cfg daytime_hosts ntp1.none.such ftp_int_passive 0 ftp_testhost ftp.funet.fi inet_domain none.such nntp_hosts nntp.none.such ph_hosts pop3_hosts pop.none.such smtp_hosts smtp.none.such snpp_hosts test_exist 1 test_hosts 1 time_hosts ntp.none.such # libnetcfg -h for help $ It tells where the old configuration file was found (if found). The "-h" option will show a usage message. To change the configuration you will need to use either the "-c" or the "-d" options. The default name of the old configuration file is by default "libnet.cfg", unless otherwise specified using the -i option, "-i oldfile", and it is searched first from the current directory, and then from your module path. The default name of the new configuration file is "libnet.cfg", and by default it is written to the current directory, unless otherwise specified using the -o option, "-o newfile". SEE ALSO
