awk: get lines starting from String1 and finish String2


Hi, I'd like an easy way for getting lines starting from String1 and finish String2 with awk

Code:
cat myfile | awk '  {

bla ... 

 split($0,vk,string1) ; print vk[2] 

... bla 
 } '
I can but it ll be quite complicate... I am sure there is easy way since awk is very powerful

If you want to include the entire lines in the range, simply precede the command with /<pattern1>/,/<pattern2>/.

example:
Code:
awk '/gdm/,/lp/{ print $0 }' /etc/passwd
gdm:x:105:108:Gnome Display Manager daemon:/var/lib/gdm:/bin/false
haldaemon:x:101:102:User for haldaemon:/var/run/hal:/bin/false
icecream:x:102:104:Icecream Daemon:/var/cache/icecream:/bin/false
lp:x:4:7:Printing daemon:/var/spool/lpd:/bin/bash
You can also use sed:
Code:
sed -n '/gdm/,/lp/p' /etc/passwd

You need to give us an actual sample. But from what I'm understanding you want something like this.
Code:
$ cat file
blablaaref="http://linklinklink"blablabal

$ sed -n 's/.*blablaaref="\(.*\)"blablabal.*/\1/p' file
http://linklinklink
sed -n 's/.*pattern1\(.*\)pattern2.*/\1/p' file

this won't work if you have multiple urls on one line..
so yea, post a sample...

If I do this, I do not get all the files to download, then I ll get to look for each nunber to download separately ...lot of work

and this : "[","]"

Code:
 elinks mysite.htm  | grep  ZIP | awk '  "[","]"         {     print $0      }  '
is not working

sorry, I am learning
but awk is super cool !: http://www.grymoire.com/Unix/Awk.html

Not sure what you want exactly. Can you give an example of the input data and what you want for an output.
