[SOLVED] Simple Shell Scripting Question - Echo and Execute?

I've got a bash script which has many different commands it executes in a row. Each time the script executes one of the commands, it outputs what it is doing to the screen:

...

echo "cp -r home new"
cp -r home new

echo "mv testfile new/."
mv testfile new/.

...

I am just wondering if there is a function to execute a command and output it at the same time. Something like...

...

echoandexecute("cp -r home new")

echoandexecute("mv testfile new/.")

...

At the top of your shell script, you presumably have a line like "#!/bin/sh".  Change that to "#!/bin/sh -x".

Otherwise you can define it yourself:

echoandexecute() {
echo $1
$1
}

echoandexecute "cp -r home new"
