I want to search for a string in a file, and the output should give me the line number and line containing that string.
How can I do it?
Use grep with the -n flag. Note that line numbers are 1-indexed.
You can use grep for this.
grep -n yourString yourFile
The general tool for searching in text files is grep. To run it as you need, just try
grep -n -F "my string" files
The -F tells grep to search for exact matches of the string. Otherwise, grep searches for regular expressions.
-n tells grep to return line numbers as well.
