How to use grep to get an exact string?
Hi there,

I've search this forum and find this problem could have been solved by,
Code:
grep -ho "num=[^\]*" input_data

The input_data is,
Code:
1\11\num1=100\num2=200\newnum1=220\\@

however, what I have got is ,
Code:
num1=100
num1=220

how to get the exact string,
Code:
num1=100

Thanks a lot.

ZHEN
