How to perform a for-each loop over all the files under a specified path?

Question

The following command attempts to enumerate all *.txt files in the current directory and process them one by one:

for line in \"find . -iname \'         


        

Answer 1

More compact version working with spaces and newlines in the file name:

find . -iname '*.txt' -exec sh -c 'echo "{}" ; ls -l "{}"' \;
