how could I exclude one word ?

출처 : http://stackoverflow.com/questions/4538253/grep-how-could-i-exclude-one-word

Q.

I need something like grep ^"unwanted_word"XXXXXXXX

A.

You can also do it using -v option of grep as:

grep -v "unwanted_word" file | grep XXXXXXXX

grep -v "unwanted_word" file will filter the lines that have the unwanted_word and grep XXXXXXXX will list only lines with pattern XXXXXXXX.

EDIT:

From your comment it looks like you want to list all lines without the unwanted_word. In that case all you need is:

grep -v 'unwanted_word' file
