I presume the first asterisk is so that the */ string can be preceded by any extraneous spaces or tabs at the start of the line? Now for the interesting bit :o) {;/^function /d;p;} I think the semi-colons delimit the sed commands, is that correct? if so are the leading and trailing ones needed? so we have; /^function /d and p according to the manual d deletes the pattern space and starts the next cycle, but here you're matching a line starting with the word - function - so only that line is deleted (which is probably why the function definition isn't being output), and the p command just tells sed to print out the pattern space? So to get sed to do what I want I just need; sed -n -e '/^function /,/^ *\*\//p' sourcefile.js Which works a treat!!! :D Once again, many thanks for the elegant solution Mark - rispek init :o). Sorry to everyone else for a long winded reply but I'm not that well up on either sed or regular expressions so I thought picking it apart would ensure that I understood it correctly and that anyone else with the same level of knowledge as me could see what was going on.

Problem with HP 7310 printer (HPLIP) and CUPS, won't print
by Chris Green 07 Feb '05

07 Feb '05

Are there any HP/CUPS experts hereabouts? I'm having a problem getting my shiny new Officejet 7310 printer to work on my Slackware 10 system. It was a bit of a beast to install on Windows 2000 so problems on Linux as well are nut unexpected. I have built and installed the latest hpijs (1.7.1) and the latest hplip (0.8.7), that went fairly smoothly except that the hplip startup scripts are for RedHat so I had to do a little bit of work to integrate them into the Slackware startup. My existing Deskjet 840C and Laserjet 1150 work fine so CUPS is basically OK. However the Officejet 7310 obstinately refuses to print even though everything appears OK, jobs queue up, it looks like it should work, but no printout. CUPS does report a problem but I can't find any help on how to resolve it, on the "Manage Printers" page in CUPS for the Officejet 7310 it says:- Description: Officejet 7310 Location: Study Printer State: stopped, accepting jobs. "open device failed; will retry in 30 seconds..." Device URI: hp:/net/Officejet_7300_series?ip=192.168.13.44 I can ping 192.168.13.44 OK so the printer is connected, and I can (now) print to it from Win2k. Can anyone suggest what the "open device failed" message indicates is wrong? (I am using the support forums at http://sourceforge.net where the HP printer software is supported too) -- Chris Green (chris(a)areti.co.uk) "Never ascribe to malice that which can be explained by incompetence."

First check to see if both CUPS and LPRNG are installed, if so uninstall both and reinstall ONLY CUPS, they wont both work together. Also I have had CUPS refuse to work, and found that if one just keeps canceling and starting again sooner or later it then works, (rebooting between attempts seems to get it to go!) Have a look here to see if there is any help from those who actually know what they're doing, (unlike me).: http://www.userlocal.com/articles/slackwarecups.php Userlocal is very useful for Slackware users. -- John Seago GNU/Linux User #219566 (http://counter.li.org) AFFS (http://www.affs.org.uk/)

PC Hardware Suppliers in Norfolk?
by Keith Watson 05 Feb '05

05 Feb '05

Being something of an old fogey I like to actually go and purchase any new PC spares over the counter (that is when I'm not scrounging old kit of friends and colleagues :o) ). In addition, I like to support local businesses where I can. So do list members know what outlets for PC kit exist in Norfolk (especially in and around Norwich)? And can anyone pass on any good/bad experiences they've had? URL for websites would be good. Regards, Keith ____________ Snowflakes are one of nature's most fragile things, but just look at what they can do when they stick together.

>Have you tried inkscape (http://www.inkscape.org )? Provides pretty good >vector graphic editing facilities a la Corel. I haven't looked closely at the latest release yet but my impression is that it has some way to go before it matches the later Coreldraws. And I have been creating graphics that really push it to its limits. So I am loath to move to something that is less featured. Doctrinal purity has its limits. Allan

As far as I am aware they are old versions whereas I am using version 11 and need some of its features. Now that I have got the software and hardware that will run it all OK I don't mind using it but one would like to move to total Linux software. Allan

hello from me
by allan miller 04 Feb '05

04 Feb '05

Hello I have just subscribed to the list. My name is Allan Miller. I have been using Linux extensively for the past 4 years now. After trying various distributions I have settled on Slackware. Occasionally I try a new distribution but end up fairly quickly back with Slackware. I like its speed and simplicity of setting up (I used to dislike the others with everything hidden behind gui's). Because I like fiddling/tuning I can quite easily get lost for hours tweaking things - a bit like a car mechanic who spends hours under the bonnet tuning etc and never takes the car out on the road. And a little knowledge can be a dangerous thing. Although 99.9% of the time I boot into Linux I still use Windows within a Vmware virtual machine as I use Coreldraw a lot and there is nothing equivalent yet under Linux. It has been a bit of a solitary life as I don't know anyone else who is using Linux. regards Allan

List config
by Andrew Savory 04 Feb '05

04 Feb '05

Hi, It seems there is a problem with the ALUG main mailing list: it does not allow you to unsubscribe (or at least, it ignores unsubscribe requests). Messages to 'main-request(a)lists.alug.org.uk' with a subject of 'unsubscribe' appear to fail silently. John or Adam - could you check all is well with the list config? Thanks, Andrew. -- All views are my own - who else would want them?
