[SOLVED] How can I get only the first line in a file that starts with "1." followed by any character except a number?

Issue

I have this file

1.1some text
2.some text
1.line I need

How can I print only the first line in a file that start with "1." followed by any character except a number? I expect this:

1.line I need

my code is this

q=$(grep "^[0-9].[a-z]"  "file")
echo $q

Thank you

Solution

With your shown samples, please try following grep code. Simple explanation would be: Using grep's m1 option to print only first match and exit from program then in main program mentioning regex to match lines that start from 1. followed by a non-digit character, if match is found then print the line.

grep -m1 '^1\.[^0-9]'  Input_file
