Find all files containing a specific string

grep -Ril "text-to-find-here" /

Where:

• ´i´ stands for ignore case (optional in your case).
• ´R´ stands for recursive.
• ´l´ stands for “show the file name, not the result * itself”.
• ´/´ stands for starting at the root of your machine.

Recursively counting files in a Linux directory

find . -type f | wc -l

Where:

• -type f to include only files.

• (and not ¦) redirects find command’s standard output to wc command’s standard input.

• wc (short for word count) counts newlines, words and bytes on its input (docs).
• -l to count just newlines.

If you want a breakdown of how many files are in each dir under your current dir:

for i in */ .*/ ; do 
    echo -n $i": " ; 
    (find "$i" -type f | wc -l) ; 
done
