Linux - How do I search all non-binary (text) files recursively for a certain string

Question

Linux - How do I search all non-binary (text) files recursively for a certain string

• search all files for a string
• skip binary
• recursively
• list filenames
• (and if possible echo the line + line number of the filename where it was found as option)

I was looking at Bash: passing braces as arguments to bash function and How to search for a string only in textfiles? (recursively)

But did not find an answer, only discussion

Answer 1

With GNU grep, adding the following options:

• -F or --fixed-strings
• -I or --binary-files=without-match
• -r or --recursive
• this is the default when using -r, but may be made explicit with -H or --with-filename
• -n or --line-number

So

grep -FIrn string .

See man grep.
