Finding files

[Langstracht]

I have a bunch of sub-folders which each contain an *.html file.

I need to, from the parent folder find each (.html) file which contains a 'text string'
.
There are endless command line expressions on the 'net which purport to perform this task (using find, or grep, or egrep) but I am unable to find one that works.

Why that is I have to say is a bit of a mystery.

However if anyone would be prepared to proffer a command I'd much appreciate it.

TIA.

Something like this might work:

find . -iname '*.html' | xargs grep -li 'text string'

Well, it might help if you told us what the 'text string' is (in case there's something unusual about it - special characters perhaps?) and some of the things you've tried? Anyhow here are some other things you can try

Simplest - will find instances of 'text string' in any non-binary files (regardless of extension):

grep -Ilr 'text string' /path/to/parent/

Old school (find files with .htm / .html extension (case insensitive) and grep for 'text string' in each non-binary one):

find tests -iname '*.htm?' -exec grep -Il 'text string' {} +

Using a recursive shell glob

shopt -s globstar

grep -Il 'text string' /path/to/parent/**/*.htm?

Add a lower-case -i to the greps if you want the actual 'text string' match to be case-insensitive.

find . -iname '*.html' | xargs grep -li 'text string'

worked just fine. Thanks so much.
