Question grep using variable
I have a pattern like:
Code:
column "5" is missing

PS: the no is in double quotes.

The number usally changes, so we use a loop to grep.
Code:
grep 'column "$number" is missing' filename.txt

But it is not working....

How to solve this?

Try this...

Code:
grep "column \"$number\" is missing" input_file

or

Code:
grep 'column "'$number'" is missing' input_file
