Shell Programming and Scripting

My input file is multiline file and I am writing a script to search for a pattern and move the line with the pattern and the next line to the end of the file. Since I am trying to learn awk, I thought I would try it.

My input looks like the following:

D #testpoint 1
510.0
D #testpoint2
418.0
D "#test point 3"
0.0
D #testpoint5
0.0
D #testpoint6
-50.0

My output should look like the following:

D #testpoint 1
510.0
D #testpoint2
418.0
D #testpoint5
0.0
D #testpoint6
-50.0
D "#test point 3"
0.0

This is what I have so far:
BEGIN {
RS="^[-+]?[0-9]*\.?[0-9]+?$"
FS="\n"
}
{

getline x
nf = split(x,lines," ")
if (lines[2] ~/"#test point 3"/)
{saveme = $0
getline
saveme1 = $0
getline;}
else
print $0
next
}
Thanks for any help given.

Should be something like this:

Code:

awk '
/test point 3/{
  s1=$0
  getline
  s2=$0
  next
}
{print}
END{print s1 "\n" s2}
' file

Thanks for your answer. It works, but I need to make it a stand alone module. This is what I have done, but it comes up with the following error when I run it against the source code: syntax error The source line is 15.

I modified the code as follows:

{
if ($0 ~ /#testpoint 3/) {
s1=$0
getline
s2=$0
next}
else {
{print}
}
}
END {print s1 "\n" s2}


Thanks for your help. It is much appreciated.

Post the entire script within code tags.

Hello, I resolved my syntax error. I am calling awk from within a Bourne shell script and had incorrect shell script syntax. My script now works. Thank you so much for your help.

sed is also a good way to solve your problem

Code:

sed -n '/test point/ !{
	p
}
/test point/ {
	x
	n
	H
}
$ {
	x
	p
}' a.txt
