Hi Folks

A small doubt regarding grep. I want to grep a line from a file. file goeas like this

skksjdfhglshdfgkdfmn
sdlfghsdklfgksdhfg
sdhgdfgghsdkfg
asd
skdjghkdjfg
aksjfhgkshdfgkdfd

I want to grep the last line. I know that line is starting with a, ending with d and many alphabets in between. how should I?

TIA
Shahul

To find the phase that strating with 'a' and ending with 'e':
# tail -1 |grep 'a*e'

Hi,

just one more note: You don't have to use cat here. Just shorten your command to:

egrep "^a*d$" FILE

Hi Shahul,
you could try this:

# grep "^a[a-zA-Z].[a-zA-Z]*d$"

Ernesto's reply is completely bogus! You cannot grep the output of more, because it will be cluttered with terminal escapes. more/less/pg/$PAGER/... should *always* be the last command in a chain.

And to throw in some perl :)

# perl -ne'/^a\w*d$/ and print' file

Enjoy, have FUN! H.Merijn
