Replace .htm with .html in 100's of files inside a dir

I needed to replace {.htm} files with {.html} extensions in
100's of files in a directory :

Heres what I did :

[root@unixguy scripts]# ls
file1.htm file2.htm file3.htm

[root@unixguy scripts]# for list in `ls -1t *.htm*`
> do
> prefix=`echo $list | awk -F"\." '{print $1}'`
> mv $list ${prefix}.html
> done


[root@unixguy scripts]# ls
file1.html file2.html file3.html


One more way of doing this :

[root@unixguy scripts]# ls
file1.html file2.html file3.html

[root@unixguy scripts]# ls *.html | awk -F '.'
'{print "mv "$1".html "$1".htm"}'| csh

[root@unixguy scripts]# ls
file1.htm file2.htm file3.htm

Search and replace Shell Script

Had to parse 100's of files in a loop and replace a word
called Bombay with a new word Mumbai

cat file1.dat
city name is Bombay and country is INDIA.

To:
cat file1.dat
city name is Mumbai and country is INDIA.

for file in /tmp/a /tmp/c /tmp/b ; do
sed 's/Bombay/MUMBAI/g' ${file} > ${file}.new
done

bash-2.03$ page file-name.txt
Browse or page through a text file , just like more command.

#rup
Shows host status of remote machines

example,
bash-2.03$ rup

eqtmsny2-phys.n up 3 days, 6:29, load average: 0.28, 0.26, 0.26

ffgdb1c-2.nam.n up 96 days, 18:52, load average: 0.16, 0.18, 0.18

bash-2.03$ psrinfo -v
For Processor information on a Sun System.

bash-2.03$ showrev -p
The showrev command displays the revision of a particular patch. This helps when you install a version of the patch to check if it is the latest and/or check if it is obsolete.

bash-2.03$prstat
prtstat is top in SUN os

bash-2.03$ truss -d who
truss -d and truss -D (Solaris >= 8): These truss options show the time associated with each system call being shown by truss and is excellent for finding performance problems in custom or commercial code. For example:

plimit (Solaris >= 8):
This command displays and sets the per-process limits on a running process. This is handy if a long-running process is running up against a limit (for example, number of open files). Rather than using limit and restarting the command, plimit can modify the running process.

coreadm (Solaris >= 8): In the "old" days (before coreadm), core dumps were placed in the process's working directory. Core files would also overwrite each other. All this and more has been addressed by coreadm, a tool to manage core file creation. With it, you can specify whether to save cores, where cores should be stored, how many versions should be retained, and more. Settings can be retained between reboots by coreadm modifying /etc/coreadm.conf.

pgrep (Solaris >= 8): pgrep searches through /proc for processes matching the given criteria, and returns their process-ids. A great option is "-n", which returns the newest process that matches.

preap (Solaris >= 9): Reaps zombie processes. Any processes stuck in the "z" state (as shown by ps), can be removed from the system with this command.

pargs (Solaris >= 9): Shows the arguments and environment variables of a process

Veritas Volume Manager - Setup

Veritas Volume Manager allows you to add more disk
space to existing servers.

It could be by way of storage device like EMC
or an additional Hardisk.

Assuming that we need to create filesystems intended for
an Application and:

We have 9 disks, c0t0d1 through ....................c0t0d9.

First Check if Veritas Volume Manager has seen the Disks
that you have attached :
#vxdisk -o alldgs list

if not, try the following, and then repeat the previous step:

#devfsadm

#vxdctl initdmp

#vxdctl enable

This should be able to detect disks into VVM.

Steps for setting up storage - Veritas Volume Manager

1) It is important to create a diskgroup, so that VVM can be
moved to a different hosts.

Disk Groups includes filesystems/disks of the applcations.
Commands (vxdiskadd or vxdg).

#vxdg init diskgroup diskname=device

example:
#vxdg init ABCdg ABCdg01=c0t0d1

2) Creating Volumes with vxassist:

# vxassist -g diskgroup make vol_name size

example:

#vxassist -g ABCdg make ABC01 8g

Note: Understanding the contents of the /etc/default/vxassist file is important, especially when striping disks.

3) Creating a VXFS filesystem:

#mkfs -F vxfs -o bsize=8192,largefiles /dev/vx/rdsk/ABCdg/ABC01

4) Mounting the VXFS file system.

Creating and mounting filesystems go hand in hand. You must be certain that any special flags set at creation time are reflected in /etc/vfstab, or on the command line if there is no entry in vfstab for your filesystem.

mount -F vxfs -o largefiles /dev/vx/dsk/ABCdg/ABC01 /u03/oradata/ABC

Please check this link for more reference ...
http://www.blight.com/~rick/veritas/cheat.html

Note : In Case of emergency if you need to move your entire VVM to a
different host then vxdg 'deport' and 'import' commands to
migrate an entire vxvm disk group to another host.


PS : I have VVM pdf , complete summary of commands ,
let me know if interested, I can send it across.

Veritas Volume Manager - Installation Guide

Veritas Volume Manager is also called (VVM or VxVM )

Features :
1) VVM is Available for - Windows. Linux, HP-UX, Solaris, AIX.
2) Versions (3.1, 3.2, 3.5, 4.0, 4.1, 5.0).

Installing Veritas Volume Manager

1. Insert the Veritas volume manager software cdrom into
   the cdrom drive. If volume management is enabled, it will
   automatically mount to /cdrom/volume_manager3.5
   (depending on the precise release iteration, the exact path
   may differ in your case):

2. Change to the directory containing the Veritas Volume Manager packages:
   # cd /cdrom/volume_manager3.5/pkgs

3. Add the required packages.
   Note that the order specified is
   siginificant in that the VRTSvlic package must be first,
   the VRTSvxvm package must be second, and then any
   remaining packages:
   #pkgadd -d . VRTSvlic VRTSvxvm VRTSvmdoc \
   VRTSvmman VRTSob VRTSobgui VRTSvmpro \
   VRTSfspro VRTSvxfs VRTSfsdoc
   

Once the Installation is complete as you see below:

** IMPORTANT NOTICE ***
      This machine must now be rebooted in order to ensure
      sane operation.  Execute
             shutdown -y -i6 -g0
      and wait for the "Console Login:" prompt.
# shutdown -y -i6 -g0

Give the above command as it appears in the console.

Once the system reboots, apply any Veritas volume manager
    patches. At the time of this writing, there are no patches
    for neither volume manager or filesystem. However, future
    patches (and there will be patches ;-) can be obtained from
    http://seer.support.veritas.com.
    Note that the patch installation instructions may require
    that a reboot be performed after the patch is installed
