hey guys,

for the following output:
Code:
starting
open
open
close
close
starting
close

i m able to get the text between "starting" and "close" and move them to a diffrent file like so:

Code:
sed -n '/starting/{:L;N; /close/bK; bL; :K;p;q}' >>somefile.txt

somefile.txt:
Code:
open
open

boaz733,
See this link on several different solutions for printing lines between 2 strings:

How to print only lines in between two strings using awk

If the file you labeled as "for the following output:" is your input file, then your output should look like this:
Code:
awk '/starting/ {flag=1;next} /close/{flag=0} flag {print $0}' inputfile
open
open
open
open
open

i actully managed to solve it with a loop:
it might be ugly but it works.

Code:
#!/bin/bash
x=`wc -l < datafile`
while [ $x -ge 1 ]
do
sed -n '/starting/{:L;N; /close/bK; bL; :K;p;q}' datafile>>outputfile
last_line=`grep -n -m2 starting datafile| tail -1 | cut -f1 -d:`
last_line=$(($last_line - 1))  
sed -i '1,'$last_line'd' datafile
x=`wc -l < datafile`
done

Output is :
Code:
starting
open
open
close
starting
close
starting
open
close
starting
open
open
close
