Ghostdog, Im not sure where the More Unix/Linux Forum is because I couldn't find it in this forum list.

I was able to get a code from this forum and apply it to what I'm doing. It's not exact but it's close.


code
-----
Code:
#!/bin/bash
function drcext
{
# Extract one line above and two lines below a pattern
awk '/[1-9] [1-9] /{ before-=1;after=2; next }
after { after--;next }
{ store[++before]=$0}
END {
for(i=1;i<=before;i++) {
print store[i]
}
}' b > c
diff b c > d
sed -i 's/[0-9]*,[0-9]*[a-z]*[0-9]*/----------------------------------------------------------------/g' d
sed -i 's/< //g' d
# Add a variable content to the beginning of the file
rulepath=`grep Rule d`
sed -i '/Rule/d' d
sed "1i $rulepath" < d > e
}
drcext

NOZZLE minimum width is 10um (for 14um thick material)

I'm not sure why the awk command delete the lines that are found by the search pattern [1-9] [1-9]. The originally posting for this code is for to extract the one line above and two lines below the pattern [1-9] [1-9]. This code is backward. It deletes instead of extract that's why I have to use the diff to get the lines that were delete. Please let me know how to recode it to extract instead of delete.

There is one problem with this code that I dont understand is that I use the pattern [1-9] [1-9] so it shouldn't be extracting the line:

55 55 2 May 4 16:30:30 2009

But that is what I wanted. I also want the line:

20 20 2 May 4 16:30:03 2009

But it didn't get extracted. How do I change the pattern /[1-9] [1-9] /, so that it will find any string; ie; 55 55 2 or 20 20 2? I've tried a different pattern /[1-9]* [1-9]* / or something along that line, but it's not working.

Sorry for the lengthy request but any advise would be greatly appreciated. This is my code:
