I am looking for a little regular expression help, namely
with the "{}" operators. Below is the file (inventory.txt)
that I am working with.
Jan 13 25 15 115
Jun 31 42 75 492
Jul 24 34 67 436
June 19 23 0 846
Jaa 19 23 0 846
I want to match a line that begins with "J" and then has 2
letters after it. SO, all of the above should match except
for "June"
Here is the regular expression that I'm using (in gawk):
gawk '/^J[a-zA-Z]{2}/ {print}' inventory.txt
My problem is that nothing is matched... or at least
nothing is printed on screen and I assume that nothing is
matched.
I have tried putting paranthesis around the character list,
but that didn't work either. The brace operators are
supposed to match the preceding regualar expression the
specified number of times, right? Am I not understanding
the use of the braces operators?
Thank you for your time.
