egrep lines starting with r and ending with g

Question

I need to find and display lines in the shell using egrep that start with r and end with g.

I have

egrep -e "^r*g$" testfile.txt

but it is not giving me any results, what am I doing wrong?

Answer 1

adding a . should work

egrep -e "^r.*g$"

It basically means : everything that starts with a r, then is followed by zero or more anything, and then ends with g.

tested against

r fsgdfs gfsdg
fooo bar
rfoo g
fdsqfdsq

rg

it returns

r fsgdfs gfsdg
rfoo g
rg
