suppose i want to find a pattern with grep, sed or awk,is there any way by which i can print what is in the right hand side of that pattern till the end of the line.

Code:

>cat file
patternis this the requirement

>sed -e 's/pattern//' file
is this the requirement

Is this your question?

more correctly:

Code:

sed -e 's/.*pattern//'

okay let me try them and i will inform that.
what if i want to print the info between 2 words/patterns.
e.g.
let the following line exists in a file.

this is pattern1 and this is pattern2.

if i want to pring between pattern1 and pattern2 i.e. "and this is"
then how to do it?

sed -e 's/.*pattern1$.*$pattern2.*/\1/'
should do it
or, same amount of typing
perl -pe 's/.*pattern1(.*)pattern2.*/$1/'

Code:

echo "this is pattern1 and this is pattern2" | sed -e 's/.*pattern1//;s/pattern2//'

Why do people always type the -e option when they're only using a single command? Must like typing, I guess.
