UNIX: Using egrep or sed to find the line with the first occurrence of a string?

Use this:

grep -m1 auir myfile.txt

bash unix sed

This sed command

sed -n '/auir/p' myfile.txt | head -1

solves your problem.

bash unix sed

This might work for you:

sed '/auir/!d;q' file

sed -n '/auir/{p;q}' file
