sed command that deletes lines with 3-5 digit strings
Hello!
My final exam in my Linux class is tomorrow, and I was just reviewing the grep and sed commands. I came across an example, by which I got stumped: it asks to provide a sed command that deletes all lines that contain exactly 3 to 5 digit strings, from a file.
In this case, I created a file that looks like this:
Line 1
Line 22
Line 333
Line 4444
Line 55555
Line 666666
So this sed command should print out only:
Line 1
Line 22
Line 666666
I tried the following command: sed '/[0-9]{3,5}/d' Lines.txt
but it doesn't do anything....
Could anyone please tell me my mistake?
THANK YOU!!

Folks,
Is there a simple way to replace one digit by two digit using sed.
Example,
mydigit1918_2006_8_8_lag1.csv should be
mydigit1918_2006_08_08_lag01.csv.
I tried this way, but doesn't work.
echo mydigit1989_2006_8_8_lag1.csv|sed 's/]/0]/'
