The awk solution should work, try to place the and statements between parenthesis:

Code:
awk '(/A/ && /B/) || (/A/ && /C/)' filename

i need the file names as well .. awk command doesnt gives the file names it only prints the lines.

i have many inputfiles


i need something like grep -i (/A/ && /B/) || (/A/ && /C/) *.*[~/foldername]

This will give you the filename. Works on my system. I don't have cygwin to test.

Code:
awk '/A/ && /B/ || /A/ && /C/{print FILENAME,$0}' filename

hi vidyadhar85


your soloution works with a single input file.
I have around 100 files all in one folder...
is there any way where i can ref. a folder name instead of file name?


thanks

you can specify any no of files in place of filename like filename or filename*
but change grep to grep -i to get filename in which desired pattern is present..
