Answer 1

The problem with your code is that the wildcard * is being expanded by the shell before being passed to find. Quote it thusly:

for i in `find /home/Phil/Programs/Compile -name '*.cpp'` ; do echo $i ;  done

xargs as suggested by others is a good solution for this problem, though.

Answer 2

find has an option for doing exactly that:

find /p/a/t/h -name '*.cpp' -exec g++ {} \;

Answer 3

This code works for me:

#!/bin/bash

for i in `find /home/administrator/Desktop/testfolder -name *.cpp` ; do echo $i ; 
done

I get:

administrator@Netvista:~$ /home/administrator/Desktop/test.sh
/home/administrator/Desktop/testfolder/main.cpp
/home/administrator/Desktop/testfolder/main2.cpp

Answer 4

You could use xargs like:

find folder/ -name "*.cpp" | xargs g++

Or if you want to handle files which contain whitespaces:

find folder/ -name "*.cpp" -print0 | xargs -0 g++

Answer 5

I think you want to use xargs:

For example:

find /home/Phil/Programs/Compile -name *.cpp | xargs g++

Answer 6

How about using xargs like this:

find $working_dir -type f -name *.cpp | xargs -n 1 g++
