Jump to a specific place in a file?

Shell Programming and Scripting

If I cat a file
And want to go to the first instance of a particular value - what command would I use?
And then from that point where I jumped to search for another value - but only search from that point forward not before the file?

Thanks~

To do yourself, use your editor, such as vi.

>vi filename
/particular    {would search for the word particular}
n         {would find the next occurrence}

Or, as part of a script would be potentially more involved. And would require a little more info on your intent.

> cat -n uprlwr.fmt | grep "VERSION"
    32  VERSION,4,C

That tells me that there is a reference to the word VERSION at the 32nd line in my file. By combining head and tail commands, I can extract a subset of my original file.

pattern1="fox"
pattern2="dog"
awk -v pat1="$pattern1" -v pat2="$pattern2" \ 
           'BEGIN{ found==0}
         if(found==0)         
            {if(index($0, pat1)> 0) {found=NR} }
         if(found>0  && index($0, pat2)>0) {print $0} } ' inputfile

This code starts looking for "dog" only after it finds "fox".
