How to get lines that contain string in a file?
In Linux, How do I display lines that contain a string in a text file, such as:
search "my string" file_name
How do I make the search case sensitive/insensitive? And how do I also display the line numbers?

Solution 1:
well
grep -n "my string" file_name
will do for your particular query. GREP is by default case sensitive in nature and to make it case insensitive you can add -i option to it. The -n option displays the line numbers. For other myriad options, I recommend
man grep
for more interesting pattern matching capability of GREP.
