getline question

[SpongeBob1]

Hi,

How can I modify the following to go backwards in a file, as opposed to forwards?

skip = 7
for (i=1; i < lines2skip; i++){
getline;
print

you can't - there's no &quot;ungetline&quot;.

You'll have to change your processing logic - the most straight forward approach is to save lines as they're being processed and &quot;back reference&quot; them as needed. vlad

I get you Vlad, so pipe to something & use getline to read them back in again? Or an array - that much I can do - the backreferencing I will have problems with, and tips for starting this?

 

[vgersh99]

the 'backreferencing' will be done through &quot;associative&quot; array populated as the file 'read in'.
