In the above script, opnoise is a file, I am reading it into an array and then printing the value corresponding to index 20. Well this is not my real objective, but I have posted this example to describe the problem.
The problem is when I execute the script there is no activity(no error, just a blank) and the body i.e, the print statement, execute only when I hit "ENTER" for the second time. Also gawk does not exit to command prompt automatically, I have to hit CTRL+C to exit and awk gets displayed while exiting.
Actually this what I am trying to do. I need to use the values in the array to remove certain records in file opwflightno and make a new file opwonoise. But awk is not executing beyond BEGIN. I had posted above simple example to describe the problem.

Hi there,
I'm working with file more than 400K lines, 60 columns. Column count is going to be multiple of 12: 60, 12, 72 or so.

For example: 7, 14th if only 24 columns in file.
7th, 14th and 21st if 36 columns in... (6 Replies)

I'm new to awk, trying to understand the basics.
I'm trying to reset the counter everytime the program gets a new file to check.
I figured in the BEGIN part it would work, but it doesn't.
#!/bin/awk -f
BEGIN {counter=0}

sum=0

I'd like to define an alias to awk's begin statement since I use awk with different delimiters all the time and it is tiresome to type awk '{OFS="\t";FS="\t"}{BLAH BLAH}' every time. The problem is that bash won't let me make an alias with an open quote, which is necessary for the BEGIN alias to... (3 Replies)
