I need to read each record in this file, reformat the SSN to the format #########, and write the record with the reformatted SSN to a new file. I am a UNIX newbie. I think I need to use either the sed or awk commands, but... (2 Replies)
Hey guys,
I'm trying to grep for two things out of a file and I got that working but why is it randomly throwing "--" in the output? Is there a simple way to get rid of them? It only seems to do it when the line above what im looking for has numbers in it.
$ egrep -i -B 1... (3 Replies)
Hi
I have an AWK script that takes an input file and outputs it as CSV format.
The problem is its also outputting the characters at the top which are dashes(-------) and i want it to leave them out.
My script is as follows.
BEGIN {
count=1;
}
/^/ {
count+=1
if ( count > 2 ){... (3 Replies)
My files look like this
I need to remove the columns where dashes are the majority, if any of the sequences has any character in that particular position it should be removed too. The IDs and Freqs should be kept intact. Thus, the resulting file should look like this
Thanks in advance (14 Replies)
Hi again,
What i'm trying to accomplish here is search a large directory for certain filesames, read from a txt file and looping through it.
For instance, one of my target names from the loop file is:

My loop is constructed thusly, run in a directory... (2 Replies)
I have a script to sort a list of arbitrary hosts and determine if they are supported by grepping them into a master supported list. I cut all the suffixes of the hosts in the arbitrary list, leaving the "short" hostname if you will, then grep -w them into the master list. For example:

I need to replace dashes (i.e. -) if present from positions 351-357 with zero (i.e. 0), I also need to replace dash (i.e “-“) if present between position 024-043 with zero (i.e. 0) & I replace " " (i.e. 2 space characters) if present at position 381-382 with "04". Total length of record is 413.... (11 Replies)
I need to remove dash (i.e. -) if present from positions 351-357, and then add - (dash) at 357th position. For example in following first and 3rd record we got
Before processing
1) 1st Record positions 351-357 = 0-12345
2) 3rd Record positions 351-357 = 00-4567
After processing:-

Hey Guys & Gals !
My script is creating a numbered list and I would like to have the numers and

Now to make sure it is clear which number corresonds with which outcome, I would like to have the tab space filled with dashes.

ceil
FLOOR(3M)FLOOR(3M)NAME
fabs, floor, ceil, rint - absolute value, floor, ceiling, and round-to-nearest functions
SYNOPSIS
#include <math.h>
double floor(x)
double x;
double ceil(x)
double x;
double fabs(x)
double x;
double rint(x)
double x;
DESCRIPTION
Fabs returns the absolute value |x|.
Floor returns the largest integer no greater than x.
Ceil returns the smallest integer no less than x.
Rint returns the integer (represented as a double precision number) nearest x in the direction of the prevailing rounding mode.
NOTES
On a VAX, rint(x) is equivalent to adding half to the magnitude and then rounding towards zero.
In the default rounding mode, to nearest, on a machine that conforms to IEEE 754, rint(x) is the integer nearest x with the additional
stipulation that if |rint(x)-x|=1/2 then rint(x) is even. Other rounding modes can make rint act like floor, or like ceil, or round
towards zero.
Another way to obtain an integer near x is to declare (in C)
double x; int k; k = x;
Most C compilers round x towards 0 to get the integer k, but some do otherwise. If in doubt, use floor, ceil, or rint first, whichever you
intend. Also note that, if x is larger than k can accommodate, the value of k and the presence or absence of an integer overflow are hard
to predict.
