Full Discussion: String search - Command to find second occurance
Top Forums UNIX for Dummies Questions & Answers String search - Command to find second occurance Post 302149587 by jim mcnamara on Thursday 6th of December 2007 03:59:57 PM

Other than looping or using awk, perl, or python, I have no other idea except an extreme hack like this:

Code:
#!/bin/ksh

# total line in file
wc -l inputfile | read filelen dummy

# find the line to start reading on
grep -n 'some string' inputfile | head -n 2 | tail -n 1 | read startline dummy

# subtract start line from total 
length=$(( $filelen - $startline ))

# tail the lines you need.
tail -n $length inputfile

If you are running this against a large file it will waste considerable resources.
It wastes resources anyway, because it reads thru the file several times.
