Is there some way to get bash into a sort of verbose mode where, such that, when it's running a shell script, it echoes out the command it's going to run before running it? That is, so that it's possible to see the commands that were run (as well as their output), similar to the output of make
?
That is, if running a shell script like
echo "Hello, World"
I would like the following output
echo "Hello, World"
Hello, World
Alternatively, is it possible to write a bash function called echo_and_run
that will output a command and then run it?
$ echo_and_run echo "Hello, World"
echo "Hello, World"
Hello, World
It's possible to use bash's printf
in conjunction with the %q
format specifier to escape the arguments so that spaces are preserved:
function echo_and_run {
echo "$" "$@"
eval $(printf '%q ' "$@") < /dev/tty
}
