From: Chris on 11 Aug 2010 13:26 Hi I have a file containing 2 words on 2 seperate lines: e.g. car bike I want to pipe this file through sed or awk, and only return the output only **both** words are found. Could someone help me do this? As they are on different lines grep wont work. Thanks

What output do you want? - the entire file? - just the lines containing 'car' and 'bike' ? - is order important ? - can the lines contain other text, or must the lines contain only the searched-for text? -- Fred K

You can pipe two greps but without knowing what it is that you want to output it's difficult to tell. What do you want to output? Matching lines? The whole file? The file name?

Matching lines? The whole file? The file name? I would like to return the matching lines. But only print the lines if both strings exist in the file.

So you can do, for example awk '/car/ {c++;ok=1} /bike/ {b++;ok=1} ok {lines[++count]=$0;ok=0} END {if(c && b){for(i=1;i<=count;i++)print lines[i]}}' file.txt |
