OK OK!!!! I agree its not home work question
but i didn't understand how 072 is triplet in 01072523??

if so below code will work.. I know it can be done much smaller way..but for better understanding i wrote like this

how do you print the lines before and after the line you are interested in? Example: Line to be printed: line 344
Output:
line 343
line 344
line 345

Hi Folks
Probably an easy one here but how do I get a sequence to get used as mentioned. For example in the following I want to automatically create files that have a 2 digit number at the end of their names:
m@pyhead:~$ for x in $(seq 00 10); do touch file_$x; done
m@pyhead:~$ ls file*... (2 Replies)
Dear All,
I need to find the difference between two adjacent columns. The file is having 'i' columns and i need to find the difference between two adjacent columns (like $1 difference $2; $2 difference $3; .... and $(i-1) difference $i). I have used the following coding
awk '{ for (i=1; i<NF;... (7 Replies)
Hi all,
I have a text file consisting of 4 columns. What I am trying to do is see whether column 2 repeats multiple times, and collapse those repeats into one row. For example, here is a snippet of the file I am trying to analyze:

1 Sure_Thing 14.858 0.174

Hello all! I've looked all over the internet and this site and have come up a loss with an easy way to make a bash script to do what I want to do. I have a file with a naming convention as follows:

math::calc::units
Units(3pm) User Contributed Perl Documentation Units(3pm)NAME
Math::Calc::Units - Human-readable unit-aware calculator
SYNOPSIS
use Math::Calc::Units qw(calc readable convert equal);
print "It will take ".calc("10MB/(384Kbps)")." to download
";
my @alternative_descriptions = readable("10MB/(384Kbps)");
print "A week is ".convert("1 week", "seconds")." long
";
if (equal("$rate bytes / sec", "1 MB/sec")) { ... };
DESCRIPTION
"Math::Calc::Units" is a simple calculator that keeps track of units. It currently handles combinations of byte sizes and duration only,
although adding any other multiplicative types is easy. Any unknown type is treated as a unique user type (with some effort to map English
plurals to their singular forms).
The primary intended use is via the "ucalc" script that prints out all of the "readable" variants of a value. For example, "3 bytes" will
only produce "3 byte", but "3 byte / sec" produces the original along with "180 byte / minute", "10.55 kilobyte / hour", etc.
The "Math::Calc::Units" interface only provides for string-based computations, which could result in a large loss of precision for some
applications. If you need the exact result, you may pass in an extra parameter 'exact' to "calc" or "convert", causing them to return a
2-element list containing the numerical result and a string describing the units of that result:
my ($value, $units) = convert("10MB/sec", "GB/day");
(In scalar context, they just return the numeric value.)
Examples of use
o Estimate transmission rates (e.g., 10MB at 384 kilobit/sec)
o Estimate performance characteristics (e.g., disk I/O rates)
o Figure out how long something will take to complete
I tend to work on performance-sensitive code that involves a lot of network and disk traffic, so I wrote this tool after I became very sick
of constantly converting KB/sec to GB/day when trying to figure out how long a run is going to take, or what the theoretical maximum
performance would be if we were 100% disk bound. Now I can't live without it.
Contraindications
If you are just trying to convert from one unit to another, you'll probably be better off with "Math::Units" or "Convert::Units". This
module really only makes sense when you're converting to and from human-readable values.
