Many thanks!

Hi Feherke, No typos. The first new occurrence of a number = 1 Subsequent occurrences of the same number = 2 The last occurrence of the number = 3 Hope that makes sense - what I am struggling with is being able to compare the current line with the previous one so I know when the number changes...

Hi, I have a simple input file: 1 1 1 1 2 2 2 2 3 3 3 I need to create an additional column in the file which is based on the first columns numbers: 1 1 1 2 1 2 1 3 2 1 2 2 2 2 2 3 3 1 3 2 3 3 etc Any ideas would be great! Many Thanks

Many Thanks ALL!

Hi All, Anybody know of a command (or simple script) to decimate a file by a user specified amount? e.g. I have a file that has 24 million lines and I only want to keep every 10th line. Many Thanks, James

I have nothing in /vol/dev/dsk /vol/dev exists but not the dsk directory... ls -l /dev/dsk/c* | grep stor gives me: lrwxrwxrwx 1 root root 55 Apr 11 08:25 /dev/dsk/c3t0d0s0 -> ../../devices/pci@8,700000/usb@5,3/storage@1/disk@0,0:a lrwxrwxrwx 1 root root 55 Apr 11...

Good question - i haven't installed anything extra on the machine - i assumed that because the messages file was spilling out with lots of USB related messages, and it seemed to recognize the device, that they were already installed. How do i check this? Cheers

Thanks, I tried the suggestions but got the same results as before - do you think that i need to stop/start the volume manager with the device attached?

Thanks - but if i run format, won't that destroy data on the drive?

Hi All, I am trying to mount a USB flash drive onto a Sunblade running Solaris 8 In /var/adm/messages it appears that the device is being picked up but i am getting an error: "corrupt label - wrong magic number" Doing the following appears to list the device correctly: > ls -l...

I was more after an example of decimation using your notation as it differs from the previous example that worked... Cheers!

Thanks, Can you expain "n" and "p" - i have rarely used sed...

Update to my last post - the sed command runs on my Linux (Redhat) box - just not on my Sun (Solaris 2.8). Thanks for the help!

Thanks feherke, The sed command fails - "Unrecognized command: 3~3p" - any ideas why? I can get the awk to work but only using "nawk" so thanks for that. Cheers!

Hi, I need to write a script that decimates a file by a user specified amount. e.g. Keep every 5th, 10th, 30th line etc. Is there a standard unix command that i can use to do this or should i be looking at sed or awk? Any ideas would be great. Cheers!

Thanks for the help Are you sure SWAP has to be primary - can it not be a logical partition? Is it possible to "move" a partition from primary to logical - i have used Acronis Disk director recently and that has a move option but this feels like a dangerous thing to do! Cheers

Hi All, I am trying to install RHEL WS3 on a machine that is already dual booted with XP and RH 7.3 This is what i get when i choose Manual partition mode: /dev/hda1 ntfs /dev/hda2 ext3 (/boot) # Used for RH 7.3 /dev/hda3 swap /dev/hda4 Extended /dev/hda5 ext3 (/) # Used for RH 7.3 Free...

Thanks a lot for the help - just what i need...

Thanks.. Would either of you be able to give me an example of using bc on my script? I'm a newbie, not used bc before..
