grep in a particular position

[Muktha]

Hi,
Is it possible to grep in a particular position in each line of a file.

And do what with it? Probably you want to use cut, such as "cut -c n1-n2...> and save it to a variable and compare it to whatever you need.

It depends on what you want to do with data you want to catch. A first approach could be :

egrep "^.{24}foo" --> will give you string foo beginning at 25th character.

You don't need the egrep ERE hammer. grep will work fine with regular REs:
grep "^.\{24\}foo"
