Hi Barry, I made a slightly bigger test file from your input for testing. ===================================================================== <table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>The Three Sisters, Glen Coe</td> </tr> </table> <table class="sociheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>This cannot be used</td> </tr> </table> <table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>This is different each time</td> </tr> </table> <table class="socialhear" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>This is not usable</td> </tr> </table> ========================================================================= I think the perl script below (or some modification thereof) will do what you want. ===================================================== #! /usr/bin/perl use strict; open(INFILE, "<$ARGV[0]"); my $social_flag = 0; while(<INFILE>) { my $line=$_; chomp($line); if($line=~m/\<table class\=\"socialheader\"/) { $social_flag = 1; print("$line\n"); next; } if($line=~m/align\=\"left\"/ and $line=~m/width\=\"85\%\"/ and $line=~m/nowrap/ ) { if($social_flag) { print("$line\n"); print("One new line here\n"); print("Another new line here\n"); $social_flag = 0; } else { print("$line\n"); } } else { print("$line\n"); } } close(INFILE); ============================================================== Hope this helps.

Kerberos
by Richard Lewis 02 Nov '10

02 Nov '10

Hi ALUG, I've just tried to add a new user to a Debian unstable system I manage on a virtual server but have run up against some sort of authentication problem. As normal, I used adduser: $ sudo adduser interface Adding user `interface' ... Adding new group `interface' (1002) ... Adding new user `interface' (1002) with group `interface' ... Creating home directory `/home/interface' ... Copying files from `/etc/skel' ... But then it said this: Current Kerberos password: passwd: User not known to the underlying authentication module passwd: password unchanged Try again? [y/N] n Hitting n continued like this: Changing the user information for interface Enter the new value, or press ENTER for the default Full Name []: Interface2011 Room Number []: Work Phone []: Home Phone []: Other []: Is the information correct? [Y/n] y It seems I can't set a password for this user now: $ sudo su interface $ passwd Current Kerberos password: passwd: User not known to the underlying authentication module passwd: password unchanged I've heard of Kerberos and it all sounds great, but as far as I know, I don't "use it" (if that's the right expression) on this system. And I'd prefer just to use an ordinary UNIX password, because I just want it to work. I tried commenting out a line in /etc/pam.d/common-password: #password requisite pam_krb5.so minimum_uid=1000 password [success=1 default=ignore] pam_unix.so obscure use_authtok try_first_pass sha512 But I'm not whether: a) this has been effective; or b) would solve the problem anyway. Any ideas how to make it not try and use Kerberos?

Is there any way to 'ssh and cd'?
by Chris G 01 Nov '10

01 Nov '10

I'd like to set up some logins to various places around my LAN which not only ssh to the relevant place but also do a cd to a specific directory. Can anyone suggest a way to do this? By default if you give a command to ssh at the end of the line then it executes that command and then closes the connection - it only keeps the connection open if there is no command at the end. In addition doing a cd is even a bit more difficult because it's no use at all to execute it in a sub-shell. -- Chris Green

<table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>The Three Sisters, Glen Coe</td> </tr> </table> I have over 2500 pages with the above HTML in ( the "Three Sisters, Glen Coe" bit is different in every file) and I want to add two lines so: <table class="socialheader" width="100%" border="0"> <tr> <td width="85%" align="left" nowrap>The Three Sisters, Glen Coe</td> <One new line here> <Another new line here> </tr> </table> The pair of lines to be inserted is identical in each case but the only unique identifier is the "class=socialheader". Is there any way I can do it with a script? -- Barry Samuels http://www.beenthere-donethat.org.uk The Unofficial Guide to Great Britain
