Each call to print produces a <newline> character in the output. You could try something like:
Note that I changed the format string for your printf call. If $4 happens to contain any % or \ characters, you could end up with output significantly different from what you might expect; using the format %s avoids that possibility.

I have a script problem that I am not able to solve due my very limited understanding of unix/awk.
This is the contents of test.sh

I find an script with awk sitting around. I went through some online manuals, but I can't figure out exactly how it works. I can't post the whole program. Not allowed.
This is the line that is confusing me. I get when else is in the script

Here's a basic awk program I am trying to run. It shows no error but shows no result either too. If someone can look up and tell me what's wrong I will be obliged.
Thanks. :)

Hi,
Sorry if this is a newbie question. I guess you can use either awk or shell script for this sequence of operations, but knowing very little about either of them I'm not sure how I should try to write this.

rec_10|1+2+2-
Output:

Basically I am trying to calculate the result of "the path" in $3 where the operators follow the number and not preceding them like we normally do:

But I realise (I am sure there is a good reason for that) that awk... (7 Replies)
1. increase file space
first, double space a file:
awk '1;{print ""}'

awk '1;{print "\n"}'
doesn't it meaning print a blank line every time too?
2. number each line of file, but... (6 Replies)
