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

Use command substitution instead of quotes to execute find instead of passing the command as a string:

for line in $(find . -iname '*.txt'); do 
     echo $line
     ls -l $line; 
done
