Programming :: Use A Regular Expression In Parantheses Like ([/+[]()]) To Get The Specific Letters?
May 3, 2010I found such simple example of awk
Code:
awk '
BEGIN { a = "1abc 2def"
b = gensub(/(.+) (.+)/, "\2 \1", "g", a)
print b }'
However I don't understand why the regular expresion in parentheses doesn't work how I woud expect. If I delete the .+ so it does the same.
Code:
awk '
BEGIN { a = "1abc 2def"
b = gensub(/() ()/, "\2 \1", "g", a)
print b }'
I wanted to use a regular expression in parantheses like ([/+[]()]) to get the specific letters.
Code:
awk '
BEGIN { a = "1abc 2def"
b = gensub(/([/+[]()])/, "//\1", "g", a)
print b }'
But why the regexp in () isn't working

Mar 21, 2009Once you have VLC open, select file, it only lists certain file types. Now if you go down to the bottom you can tell it to use other types (like *.*). How does one set it so one does not have to go down and change the file types every time? So that it shows all file types, all the time, by default.

View 13 Replies View RelatedCentOS 5 Server :: What Storage Type To Choose?
Jun 21, 2011We new have server with VmWare ESXi4.1 and we created virtual machine with CentOS5.6.This CentOS5.6 virtual machine will be used as webserver. We need to backup all files and have access to these files. We are going to keep all websites, databases, backups on data storage (NetApp FAS2000 series).
We have two options to how to use this storage:
1: We can mount storage volume directly to CentOS5.6 by NFS.
2: We can add storage via NFS to VmWare and then add new virtual disks to CentOS5.6 by VmWare vSphere client.
What option would you recommend to use? Which option is better, faster and more secure? My thoughts:If we mount storage volume directly to CentOS5.6 so we can access .snapshot directory there is all snapshots. So it's easy to access all backed up files. NetApp has snapshot system and we can schedule to make snapshots automatically, so we don't need to setup any additional backup utilities in CentOS5.6. But we don't have any NetApp snapshot restoring software license so copy/paste from .snapshot directory is only option.
If we add storage to VmWare firstly (by NFS) and then add new virtual hard disks to CentOS5.6 by VmWare vSphere client so we have to setup rsnapshot(or any similar utility) to make backups in CentOS5.6. But NetApp will also make backups of .vmdk files. So it's like double backups, lol :) If storage crashes so we screwed in both ways, I think.

CentOS 5 Hardware :: Displaying Error On Console ?

View 2 Replies View RelatedCentOS 5 :: Prevent Certain Errors From Displaying On Console / Set That Up?
Jan 26, 2011We are currently troubleshooting the following error, which was repeatedly being displayed on the console:
kernel: Northbridge Error, node 2<0>K8 ECC error."
After replacing all of the memory, the error remained, so we tried updating to the latest kernel. (Currently having to use centos-plus because we are using XFS)
After the kernel update the error disappeared fro 5 days (previously UNHEARD of - would often repeat several times a day), it appeared again and hasn't appeared since.
It does not seem like any real damage is done here - and I would like to suppress this error somehow. Optimally I would like it to only be forwarded to the log files - and NOT be displayed on the console.
Could someone point me to an easy way to set that up?

Feb 4, 2011In my system around 73gb(pc-desktop) i have,1 primary partition(windows)-25gb, 1-extended partition(remaining gb) 3 logical partitions were there in (under) extended partition in one of the logical partition is d:drive. in my hard disk d: drive is -/dev/sda5
previosly i was fat -file system , (d:drive-/dev/sda5), i remember i changed the d: drive(d:drive-/dev/sda5) file system to ext4file system ,with following command using terminal
After doing(changing the file system)this one ,i couldnt see the d:drive data
By doing that
1q) Did i reformatted the partition? i think the new filesystem(ext4) has no knowledge of the data that was on it when it had a FAT filesystem.
2q) How to do undo operation,i tried to change the filesystem type to fat/ntfs in terminal using command --sudo mkfs -t FAT /dev/sda5.
Result:its showing text message-'mkfs.FAT: No such file or directory'(not in single quote)
I had very imp data in d:drive
