multiple grep in one? Solved

Question

Hello,

To find one or multiple lines containing the info I want, I do:
grep "info1" filename | grep "info2" | grep "info3" | fgrep "info4"

I was wondering if there is a way like:
grep "info1" "info2" "info3" "info4" filename

Thank you

to jipicy & bob031
your solutions give "search for a line containing info1 or a line containing info2 or a line ...."

I'm looking more for "search for a line containing info1 and info2 and info3 ..."

PS: I'm using GNU grep 2.5.4

maybe this:  grep -E "(pattern1|pattern2|pattern3)" your_file  a penguin on the ice floe!

mortelrdv · Answer

no, it doesn't work

jipicy · Answer

grep "info1.*info2.*info3.*info4"  -- $ man woman There is no manual page for woman. GNU/Linux: Gnu/Linux is Not Ubuntu!

bob031 · Answer

or this

egrep -w 'pattern1|pattern2|pattern3|pattern4' your_file

grep -E 'pattern1|pattern2|pattern3|pattern4' your_file

?

note: the patterns must be in the order of appearance or ... it won't work!

Extrait de "info grep" :  10. Je peux faire un OU avec '|', mais qu'en est-il du ET? grep 'paul' /etc/motd | grep 'françois' trouve toutes les lignes qui contiennent à la fois 'paul' et 'françois'  Donc ta solution de départ était la bonne ;-))  -- $ man woman There is no manual page for woman. GNU/Linux : Gnu/Linux n'est pas Ubuntu !
