version info :
vi availabe with RHEL 5.4
I have a text file with 10,000 lines. I want to copy lines from 5000th line to 7000th and redirect to a file. Any idea how I can do this?
Note:
The above scenario is just an example. In my actual requirement, the file has 14 million lines and I want to copy 2000 lines after the 12th million line
BTW.I've just realised that the vi editor we use in RHEL is actually VIM
Code:
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 5.4 (Tikanga)
$
$ which vi
/bin/vi

REDHAT-UPGRADE-TOOL(8) redhat-upgrade-tool User Manual REDHAT-UPGRADE-TOOL(8)NAME
redhat-upgrade-tool - Red Hat Upgrade tool
SYNOPSIS
redhat-upgrade-tool [OPTIONS] SOURCE
DESCRIPTION
redhat-upgrade-tool is the Red Hat Upgrade tool.
The redhat-upgrade-tool client runs on the system to be upgraded. It determines what packages are needed for upgrade and gathers them from
the source(s) given. It also fetches and sets up the boot images needed to run the upgrade and sets up the system to perform the upgrade at
next boot.
The actual upgrade takes place when the system is rebooted, using the boot images set up by redhat-upgrade-tool. The upgrade initrd starts
the existing system (mostly) as normal, lets it mount all the local filesystems, then starts the upgrade.
When the upgrade finishes, it reboots the system into the newly-upgraded OS.
OPTIONS
Optional arguments
-h, --help

--reboot

SOURCE
These options tell redhat-upgrade-tool where to look for the packages and boot images needed to run the upgrade. At least one of these
