How to grep more then one word?
I need to find in a given file (text) all lines containing the word 'bla' AND all lines containing the word 'blue' and so on...
The following command is not good because it gives the lines containing all words:
cat text | grep bla | grep blue

Thanx

Try this
cat <file> | grep -i -E "xls|jpg|bmp|doc|etc"

cat is unnecessary. You can do it this way

grep -E "one|two|three" file.txt

With cat you must read the entire file first and then direct the output to the grep. If you have a small file this is fine, but if you have a very large file, say 1mb or more, like as in a log file, it will have a delay and take time away from your other application processes since 50% of all time slices are reserved for the OS and root, at least on HPUX that is the way it is.

Champ, this is a forum you can add commentary. Smilie You might need to download a newer version of grep for your sparc. Most modern versions of grep support -E.

Of course, your version of UNIX must support the -E option. If you don't have it you must use either:

egrep or

grep -e text -e "text" file.out

On SunOS, /usr/xpg4/bin/grep is a modern grep that supports -E.

Hi, When we "grep" for a word in a file, it returns the lines containing the word that we searched for. Is there a way to display only the words and not the entire line containing them. Thanks Ananth (6 Replies)
