Recursively find all files containing 'string.txt' in file name [duplicate]

Question

I want to recursively search for all files and sub-directories within a directory with sub string within file name as 'string.txt'

My command:

   cd /home/abcd/dir
   grep -R "*rate-trace.txt" | wc -l

Answer 1

grep is searching the file's content.

Use find command instead:

find /home/abcd/dir -type f -name "*rate-trace.txt" | wc -l

OR

cd /home/abcd/dir
find . -type f -name "*rate-trace.txt" | wc -l
