Could you please try this and let me know if this helps.
Above will print the matching line also, if you want to leave that matching line then following may help you in same.
Also considering that there are 98 line present after the match into the Input_file. Let me know on same.
Thanks,
R. Singh

Hi all,
I'm new to shell scripting.
I want to copy initial few lines(say first 10 lines) from a file to another file.
There is no "head" command in our embedded system.
sed & awk is there which I believe will do that, but I dont know how to.
This is linux 2.6 (embedded)
So please help me.... (5 Replies)
I have a command which prints #lines after and before the search string in the huge file
nawk 'c-->0;$0~s{if(b)for(c=b+1;c>1;c--)print r;print;c=a}b{r=$0}' b=0 a=10 s="STRING1" FILE
The file is 5 gig big.
It works great and prints 10 lines after the lines which contains search string in... (8 Replies)
Hi,
I have a big (2.7 GB) text file. Each lines has '|' saperator to saperate each columns.
I want to delete those lines which has text like '|0|0|0|0|0'
I tried:
sed '/|0|0|0|0|0/d' test.txt
Unfortunately, it scans the file but does nothing.

Hi Guys,
I have an awk script that would search the input file for line that starts with a number 3 and copies into a new text file.
I want to extend this script to find the lines that either starts with 3 or a or b and copy all those lines into the new file.
Here is what I have so far:... (1 Reply)
Hi,
I need a unix command to delete first n (say 100) lines from a log file. I need to delete some lines from the file without using any temporary file. I found sed -i is an useful command for this but its not supported in my environment( AIX 6.1 ). File size is approx 100MB.
Thanks in... (18 Replies)
Requirement:
When I do ls -ltr /home/data/orders I get a huge list of files, I need to copy that last 50 to another directory say /home/work/ later, I will do my ETL process and then again I need to copy from 51 to 100 and so on.
What is the command to copy files specifying 1 to 50... (5 Replies)
Hi All,
I am trying to get some lines from a file i did it with while-do-loop. since the files are huge it is taking much time. now i want to make it faster.
The requirement is the file will be having 1 million lines.

x86_energy_perf_policy
X86_ENERGY_PERF_POLICY(8) System Manager's Manual X86_ENERGY_PERF_POLICY(8)NAME
x86_energy_perf_policy - read or write MSR_IA32_ENERGY_PERF_BIAS
SYNOPSIS
x86_energy_perf_policy [-c cpu] [-v] -r
x86_energy_perf_policy [-c cpu] [-v] 'performance'
x86_energy_perf_policy [-c cpu] [-v] 'normal'
x86_energy_perf_policy [-c cpu] [-v] 'powersave'
x86_energy_perf_policy [-c cpu] [-v] n
DESCRIPTION
x86_energy_perf_policy allows software to convey its policy for the relative importance of performance versus energy savings to the proces-
sor.
The processor uses this information in model-specific ways when it must select trade-offs between performance and energy efficiency.
This policy hint does not supersede Processor Performance states (P-states) or CPU Idle power states (C-states), but allows software to
have influence where it would otherwise be unable to express a preference.
For example, this setting may tell the hardware how aggressively or conservatively to control frequency in the "turbo range" above the
explicitly OS-controlled P-state frequency range. It may also tell the hardware how aggressively is should enter the OS requested C-
states.
Support for this feature is indicated by CPUID.06H.ECX.bit3 per the Intel Architectures Software Developer's Manual.
Options
-c limits operation to a single CPU. The default is to operate on all CPUs. Note that MSR_IA32_ENERGY_PERF_BIAS is defined per logical
processor, but that the initial implementations of the MSR were shared among all processors in each package.
-v increases verbosity. By default x86_energy_perf_policy is silent.
-r is for "read-only" mode - the unchanged state is read and displayed.
performance Set a policy where performance is paramount. The processor will be unwilling to sacrifice any performance for the sake of
energy saving. This is the hardware default.
normal Set a policy with a normal balance between performance and energy efficiency. The processor will tolerate minor performance compro-
mise for potentially significant energy savings. This reasonable default for most desktops and servers.
powersave Set a policy where the processor can accept a measurable performance hit to maximize energy efficiency.
n Set MSR_IA32_ENERGY_PERF_BIAS to the specified number. The range of valid numbers is 0-15, where 0 is maximum performance and 15 is max-
imum energy efficiency.
NOTES
x86_energy_perf_policy runs only as root.
