Shell Programming and Scripting

Using following way also you can get the getTotalAmount() from test.txt.

cat test.txt | cut -d ' ' -f 3

Thanks for the replies guys

The solution proposed by abubacker fits a lot my requirements
cat test | sed -nr 's/.*(get[a-zA-Z]*\(\)).*/\1/p'

Actually in the test.txt file I have more than one gets

for eg

asdasda getAmount() asdasda
adsadaa getTax() adasd

etc

Hence this expression matches exactly

Thanks a lot for the solutions.

I was looking to find a solution with grep, and this is a best option... -o

I just changed a bit to fit my requirements. I just added a get at the beginning.

grep -o "get[a-zA-Z]*()" test.txt
