I know that is possible to use for loop with find command like that
for i in `find $something`; do (...) done
but I want to use find comma
You want to use find command inside an if condition , you can try this one liner :
[[ ! -z `find 'YOUR_DIR/' -name 'something'` ]] && echo "found" || echo "not found"
example of use :
[prompt] $ mkdir -p Dir/dir1 Dir/dir2/ Dir/dir3
[prompt] $ ls Dir/
dir1 dir2 dir3
[prompt] $ [[ ! -z `find 'Dir/' -name 'something'` ]] && echo "found" || echo "not found"
not found
[prompt] $ touch Dir/dir3/something
[prompt] $ [[ ! -z `find 'Dir/' -name 'something'` ]] && echo "found" || echo "not found"
found
