remove everything from starting until some keyword

fad216 · 03-24-2011, 02:14 AM

hello everyone...

I have a multiple txt file in one folder. I would like to remove everything from starting until find string keyword in one folder. Here is the sample of my text:

Code:

5a651a62sf1a54f2a1sf6a4f50a5f4a2f1a2d1sfs11231211f61d021sd1fs1Reassembles21f2sdf122dfs21fs212sdfdsf1s65f1s62f1

So i want to remove everything from starting until reassemble. Here is the sample output:

Code:

s21f2sdf122dfs21fs212sdfdsf1s65f1s62f1

I have multiple file in one folder. So how to use any script to read in one directory folder and do a same task. I prefer using awk, sed or perl.

Thank you...

something like this?

Code:

#!/bin/env perl -p

$y="s21f2sdf122dfs21fs212sdfdsf1s65f1s62f1";

's/.*(?=$y)//'

split on Reassemble, then get the last element.

Code:

$ ruby -ne 'puts $_.split(/Reassemble/,2)[-1]' file

$ sed -i 's/^\(.*\)[Rr]eassemble//' *.txt

you don't need to group if you are not using backreference.
