Copy entire content from a folder to another in shell script

Question

I'm trying every single code to copy all things inside a folder to another but i can't do it! I'm trying to use the code in my terminal emulator in my android device because i need that code in my application. This is the last code i use that doesn't work:

#!/bash/sh
srcdir="/data/app"
dstdir="/sdcard/prova1"

for f in ${srcdir}/*.apk
do
    cp $f $dstdir $dstfile
done

and the terminal says:

: not found
' unespectedsyntax error: 'do

can anyone help me? These are the possibility that could be good:

1) Copy all files in the /data/app folder to /sdcard/prova1

2) Copy directly the folder app in prova1

3) Use a java code that do one of these two things..

I have root so i can do this operation.

Answer 1

None of these answers worked for me for recursive copy. Found this in a script in one of my libraries and thought I'd share it (with a subfolder example for both the source and destination, which is what I needed):

SOURCE="/my/folder"
DESTINATION="/my/destination"

cp -r "$SOURCE/subdir/"* "$DESTINATION/another_sub/"

With this, every subfolder and every file was copied.

I don't know why but the asterisk outside the quotes in the source did the magic for me (using bash 4.3.11 here)

Answer 2

how about this, where src and dest are directories: cp -r src dest
