Is there a way to use the grep command in conjunction with an editor such as nano or vi so that I can remove the commented out lines from a conf file and then proceed to edit it ? I can use grep -v "^#^" squid.conf (example ) which gives me a nicely tidy conf file but I can't edit it.Can this command be used with nano or ?

View 1 Replies View RelatedHow to device-mapper multipathing in conjunction with fdisk. I am more of a solaris expert and now trying to grasp linux (red hat). I have a server that I plan to cluster (future assignment) which is attached to a Netapp SAN via emulex LPe11002 HBA. I have 8 paths to the LUN I created and I can see the multipath device (/dev/mapper/mpath1). Below is my multipath.conf file:
[Code]....
Question 1: When I look at fdisk -l, I can see all 8 paths to the same LUN. Although I partition /dev/mapper/mpath1, I can still see that 7 of the 8 still say "Disk /dev/sdX doesn't contain a valid partition table". I would think that all 8 would have this removed. I execute '/usr/sbin/lpfc/lun_scan all' and it doesn't work. I am looking to clean this up...what should I do? It seems weird to have to do it to all 8 paths!
Question 2: Why does my alias, 'db' not show up under /dev/mappers?
Question 3: Is there a way for fdisk -l to display one lun rather than displaying all 8 paths to the lun?
What is the standard procedure (commands) people execute when adding a new lun to a server with multipathing so it is nice and clean?
So theres this command
Code:
man -k mail
Which lists commands that contain the keyword "mail" in their description.I want the output of this command in less and the words highlighted by grep. Something like
Code:
man -k mail | grep mail | less

I have a requirement to find the files having its name as ack_reply. However, there are many other files in the same directory as these resides. Now I have to remove these files from the folder and retain others after 7 days. So I tried to write the below script with grep command.

I have a 500G HD with several partitions. I have just added another exact 500G HD and would like to copy the partition table from the first HD to the new HD.What is a good command line partition editor to get the job done? All of my partitions are ext4. I have looked at parted but the man pages says it does not support ext3, so I guess it will not work with ext4 either.What I am ultimately going to do is to set these two HD in a RAID0 configuration without having to re-install Karmic.

View 14 Replies View RelatedOn windows I really only used Notepad++ as my text editor, it had two features that I loved.What I need to accomplish is what I would do with Notepad++ column editor.I could have like 100 lines, and place the cursor at a column, and goto edit>column editor, and I could insert an incrementing number. (I could also pad the incrementing number with 0s, this was GREAT for making batch files among other things.)So each line at that column had a number higher than the previous line.The other feature that I used sometimes was a search/replace with regex patterns.Does anyone know of an editor that has those features for linux? I am mostly after the column editor insert feature but if you know of one with both features that would rock.
