Programming :: Print NaN Using The Awk?
Jun 24, 2010
I want to print NaN value in a file containing of 3600 rows and 7 columns.The illustration of output file which I want to is as follows :
NaN NaN NaN NaN NaN NaN NaN (the first row)
NaN .... NaN
.
.
.
NaN .... NaN (the 3600 rows)
I tried to use below command
awk 'BEGIN {for(i = 1; i <= 3600; i++); printf "%s", "NaN", $1" "$2" "$3" "$4" "$5" "$6" "$7}' > output
Unfortunately, I couldn't get what I want to.

Say I have a line like such:
Code:
today 2010 Feb 21 test10, 12AM
How would I print everything AFTER "2010 Feb 21 "?
What I thought to do so far is to set a variable to the format used in the string like so:
Code:
date="$(date +%Y %b %e)"
So I know I have to use either awk, sed, or perhaps bash substrings to work with the variable $date, but as to how, I'm drawing a blank.

problem statement:
pattern_search="Exam Name"
sed -n "/$pattern_search/,/hello/"p tmp5 | awk '{if ( $4 != 0 && $4 ~ /[0-9]+.*[0-9]*/ ) print "$pattern_search" " " $0 }'
"tmp5" is a file. this is printing output as
$pattern_search value1
i.e value of $pattern_search is not getting substituted. i am expecting output as
Exam Name value1

I have a site which will have, for example, a login system where people have to enter their usernames and passwords, depending on which they'll be let in to the site. So, in code, I've got a line like:
if ($_POST['password'] == $password) {
then do whatever
}
else { print "Wrong password" ; )
My problem is, this "Wrong password" printing is just a solitary line, not keeping with the colours and style of the site, and it looks very bad. I want to ideally, output some HTML, which will have a picture, and print the "Wrong password" in the font and colours I desire. Do I have to put all the HTML in a print statement, and then deal with the nightmare of escaping all the quote marks in it with a ""? Or is there a cleaner method to the whole thing? Maybe something like this -
if ($_POST['password'] == $password) {
then do whatever
}

I've just started programming at my university and I'm finding it a bit hard to get started. I've been given this for homework.Given 2 integers, a and b, print their sum. However, sums in the range 10..19 inclusive, are forbidden, so in that case just print 20The problem I'm having is that i don't know how to tell java to print 20 when the value is in that range.

I am trying to write a program that monitors when an lp or basically any sort of print command is issued. If a print command is detected I want to pause that job and ask the user if he / she wants to continue.
This program would run in the background all the time so it can't sit and eat up a lot of cpu. I tried a simple while loop that continuously monitored "ps" and that obviously boosted my cpu to 100%.

I need some direction on a small scripting question. I've been doing some development and storing the code on a network drive with multiple user access. My development is getting complex enough that it is time to set up a svn repo for it. I would like to set up a little script (if possible) that prints a message/reminder to whomever is accessing the code directory stating that the code is ultimately stored in svn and any changes need to be checked in, etc. Is there a way to have linux print a message to the screen based on a 'cd /specific_dir/' command? So far google is mum on the topic. Using Debian and bash shell.

I am using an awk command to print a line from a cvs file.the awk command includes an if statement that filter the output-lets say i want to print all the lines that the price field is greater than 30.i have it working when i put the parameters myself.. but when i try to send them with vars it wont work..i am sending the sign of the if statement - can only be: == , < , >it looks like this:
cat file.csv | awk -v sign=">" -v field="2000" '{if($3 sign field) printf "%-12s%-12s%-12s%-12s
",$1,$2,$3,$4}' FS=,
the bold part is the problem , because when i put the sign parameter myself t works great.. i guess its a chars issue but i cant spot it

I have a file with variable length lines containing fields separated by colons:
Code:
path/to/file0.c:4150:109:4151:142:4153:275
path/to/file1.c:4040:109
path/to/file2.c:4605:72:4606:109
path/to/file3.c:4380:54
The first field identifies the file name, the second is the search key, and the third is the line number of the file that the search key points to. Any subsequent fields are other key/line number pairs.
As an example, I can search for 4151 (key) from my bash script to identify the file I will have to access, but I also need to capture the line (142) as well, and I can't figure out how to do that using grep, awk or sed (or anything else).

I have a directory where there are folders and in them some .txt data files. I am trying to output a .txt file with the folder name and the number of .txt files in it using gawk. However, when I run my shell program, because print is nested in a "while" loop, gawk overwrites what's already saved in the output file. I want gawk to print "new" output in a new line without overwriting the already existing text in the output fil
#! /bin/sh
# getting the folder list and the number of folders
ls | gawk '{print}' > ../folder_list.txt

As you know, in C++ you can use setfill(char c); and setwidth( int length) to fill a line of a character.
It's line making a line of a character for output
Code:
NAME DEPARTMENT LOCATION
==========================================
Pete R&D Chicago
...
==========================================
As you see, a line of a '=' character drawn to output.
I'm wondering, how can I draw this line in C using printf() to format?
( no loop or repetiton )

Can one of you point me towards a comprehensive print function tutorial in perl? I was under the impression that everything within quotes will get interpolated - but I am running into exceptions where it is not desirable to run some varaibles under quotes.

2 $idx = 1;
3 foreach $letter (a..z) {
4 print "Letter #",$idx++," is: $letter

From a file I want to extract a range of lines by patterns. I've used variations on
Code:
sed -n -e '/^BashNotes/,/^EndOf[A-Za-z]*$/ p' -e '/^EndOf[A-Za-z]*$/ q' Notes
So, I want to extract lines starting from one whose first word is specified, in this case "BashNotes", and ending at the first line consisting of the single word "EndOf...", which in this case would be "EndOfBashNotes".
Either I get no output at all, or it prints from the start of file to the first EndOf..., so the problem has to be with "^BashNotes", e.g. remove the "^" and it accesses an earlier occurrence of "BashNotes" that is in the middle of the first line of the file, and prints to the first occurrence of "EndOf...".
So why should a "^" in the "from" pattern be objectionable, when it is acceptable in the "to" pattern and the "quit" statement?

The problem I have is that the script moves to a standalone window to show the results. I am interested in making it "popup' a window with the results.

Program in CSay I have a char array of 1024 bytes called buf1.But I only want to print the chars in index 0 up to index 30. I know I could do this with a for loop. But is there any other way? What about maybe storing from 31-1024 to another char array say buf2 with strcpy and somehow popping 31+ out of the buf1 char array?
