You already have fitting answers in your other threads:

Where is the specific problem in this case?

Hi
In those I know what to filter but in this case it can be anything so I need to display all the lines and want to select a particular line and print the same.

Hi,

You can get the line in a file by grep cmd.

grep 'pattern' file

awk '$0 ~ /^pattern/{print;}' file

You can get line by line number( below example gets 10th line).

perl -ne 'if($. == 10){print;}' file

Cheers,
Ranga:-)

Anything can be everything so that does not help and a computer doesn't know. If you want to filter more than one pattern, try:

grep -E "pattern1|pattern2|pattern3" infile
