I’m doing a directed study on operating systems, and I’ve stalled on that question:
4) Using the egrep programme in conjunction with the programme
wc
, tell how many letters "a" there are in the messages.txt file .
I thought it was this way:
egrep "a" mensagens.txt | wc -c
but it is not, if anyone can help me I will be very grateful.
vlw, it was right
