You never seem to be willing to show us that you have done any work yourself.
You always seem to be unwilling to use the obvious tools that can easily do the job you want done.
Is this a homework assignment? If not, why are you restricting the commands that can be used?
What OS and shell are you using?

Hello
I have a file with nearly 90000 lines in x,y,z format but have some lines that I do not need to show. Is there anyway to delete those 3 lines after every 288 lines.
Eg I keep the first 288 lines delete (289, 290 291); keep the next 288 lines after those and so on...
Thanks (6 Replies)

format::human::bytes
Format::Human::Bytes(3pm) User Contributed Perl Documentation Format::Human::Bytes(3pm)
NAME
Format::Human::Bytes - Format a bytecount and make it human readable
VERSION
Version 0.05
SYNOPSIS
Ever showed 12345678 bytes to the user instead of just saying 11MB? This module returns you a printable string which is more readable by
humans than a simple bytecount.
use Format::Human::Bytes;
$readable = Format::Human::Bytes::base2($bytecount[,$decimals]);
$readable = Format::Human::Bytes::base10($bytecount[,$decimals]);
$readable = Format::Human::Bytes->base2($bytecount[,$decimals]);
$readable = Format::Human::Bytes->base10($bytecount[,$decimals]);
my $fhb = Format::Human::Bytes->new();
$readable = $fhb->base2($bytecount[,$decimals]);
$readable = $fhb->base10($bytecount[,$decimals]);
All functions do "intelligent" switching to the next unit, for example:
1000 => 1000B
[...]
8000 => 8000B
9000 => 9kB
The difference between 1000 bytes and 1500 bytes is usually bigger (for example because of a slow link) than between 95kB and 95,5kB. The
same applies to 8000kB vs. 9 MB and for the other units.
Depending on your usage, you may want to specify how many decimals should be shown (defaults to no decimals).
FUNCTIONS
/ METHODS
new
my $fhb = Format::Human::Bytes->new();
Creates and returns a Format::Human::Bytes - object.
base2
Callable as a function:
$readable = Format::Human::Bytes::base2($bytecount[,$decimals]);
Callable as a class method:
$readable = Format::Human::Bytes->base2($bytecount[,$decimals]);
Callable as a object method:
$readable = $fhb->base2($bytecount[,$decimals]);
Returns the correct readable form of the given bytecount.
Correct in this case means that 1kB are 1024 Bytes which is how computers see the world.
If you specify a decimal parameter, the result number will have the number of decimal numbers you specified.
base10
Callable as a function:
$readable = Format::Human::Bytes::base10($bytecount[,$decimals]);
Callable as a class method:
$readable = Format::Human::Bytes->base10($bytecount[,$decimals]);
Callable as a object method:
$readable = $fhb->base10($bytecount[,$decimals]);
Returns the incorrect readable form of the given bytecount.
Incorrect in this case means that 1kB is 1000 Bytes and 1 MB is 1000000 bytes which is how some (many) people see the world, but it's wrong
for computers.
If you specify a decimal parameter, the result number will have the number of decimal numbers you specified.
