Hi All,
I have been working on awk and arrays. I have this small script:

This gives me the number of mails users are getting. ... (1 Reply)
Been struggling with a problem, I have been trying to do this in awk, but am unable to figure this out, I think arrays have to be used, but unsure how to accomplish this.

Hi,
I have spent the afternoon trawling Google, Unix.com and Unix in a Nutshell for information on how awk arrays work, and I'm not really getting too far.
I ahve a batch of code that I am pretty sure can be better managed using awk, but I'm not sure how to use awk arrays to do what I'm... (1 Reply)

Hi
Can someone please explain the logic of awk arrays. I have been doing some reading but I dont understand this:
#!/usr/bin/gawk -f
{
arr++;
}
end
{
for(i in arr)
{
print arr,i
}
}
As I understand arr refs the arrays index, so while $2 is a string that cant... (2 Replies)
Hi, buddies
I am new to shell scripting and trying to solve a problem. I read about arrays in awk that they are quite powerful and are associative in nature.
Awk Gurus Please help!

I'm a little stuck and would be grateful of some advice!
I have three files, two of which contain reference data that I want to add to a line of output in the third file. I can't seem to get awk to print array contents as I would expect.
The input files are:

make
MAKE(1) General Commands Manual MAKE(1)NAME
make - a program for maintaining large programs
SYNOPSIS
make [-f file] [-iknpqrst] [option] ... [target]
OPTIONS -f Use file as the makefile
-i Ignore status returned by commands
-k On error, skip to next command
-n Report, but do not execute
-p Print macros and targets
-q Question up-to-dateness of target
-r Rule inhibit; do not use default rules
-s Silent mode
-t Touch files instead of making them
EXAMPLES
make kernel # Make kernel up to date
make -n -f mfile # Tell what needs to be done
DESCRIPTION
Make is a program that is normally used for developing large programs consisting of multiple files. It keeps track of which object files
depend on which source and header files. When called, it does the minimum amount of recompilation to bring the target file up to date.
The file dependencies are expected in makefile or Makefile , unless another file is specified with -f. Make has some default rules built
in, for example, it knows how to make .s files from .c files. Here is a sample makefile .
d=/user/ast # d is a macro
program: head.s tail.s# program depends on these
cc -o program head.s tail.s# tells how to make program
echo Program done. # announce completion
head.s: $d/def.h head.c # head.s depends on these
tail.s: $d/var.h tail.c # tail.s depends on these
A complete description of make would require too much space here. Many books on UNIX discuss make . Study the numerous Makefiles in the
MINIX source tree for examples.
