search in a very long line

[laurentiuz]

Hi everybody,

can you tell me how can I find a string in a file which has
very long lines.
I've tried grep but it respond :"can't grep line exceed ...
bytes'
I've tried a cat file_name | grep string : same thing
I tried even vi - but it shows me onli a line and I can't do a search ...
Thank you in advance !

Try using perl then - it doesn't have low limits on the lengths of files / lines.

What do you want to do with a line once you've found it?

if on Solaris, try /usr/xpg4/bin/grep
Might have better luck.

I just want to know if the string exist in that file

In bash and similar shells

perl -n -e 'if ( /string/ ) {exit(1);}' filename
if [ $? == 1 ]; then
  echo found
fi
