search string in a file and print

[cckramer]

Hi,

I have a file which has contents like this :

Indicators :

for issues with indicators contact [e-mail]

for access to indicators contact [e-mail]

Unix_Versions :

for latest unix versions check out u.versions.com/new.html

for past versions please see u.versions.com/old.html

-----------------

The keywords are indicators & unix versions

if somebody runs a perl script with any of the keywords, they should the lines corresponding to that.

Say they do, test.pl unix_versions, the 2 lines in the above file below the keyword unix_versions should be printed on screen.

---------------



how to do that ?

I think I need to read in the above file into an array.But am not sure how to go about after that.

Ok, so what have you tried thus far? Why not post your code here (encosed in code tags) and we will help you from there.

Regards,

Jeff

Note: This could be the code if the content was one line each and the keyword was enclosed(2nd word in ech line) as part of that line.But what I need is if that key word is separate line as mentioned in the original question and there is more than one line below the keyword.

may as well post my solution here too:

$request =<STDIN>;   
chomp($request);   
 
$file = "/nfs/.../.../.../file1.txt";   
my @lines = ();  
open (FILE1, $file) || die ("unable to open file: $!");   
 
LOOP: while (<FILE1>) {  
   if (/^$request :/i) {  
      while (<FILE1>) {  
         last LOOP if /^\w+ :/;  
         push @lines,$_;  
      }  
   }  
}  
close <FILE1>;  
print "@lines";
