for - do - done on seperate lines.
Also it contains
while - do - done and others on seperate lines.
Also it contains
if - then - else - fi and derivatives on seperate lines.
Also it contains
somefunction() - { - } on seperate lines.
Also it contains
` somecommand ` , also deprecated.
Although items might be deprecated does not mean they are not in use - be aware.
EDIT:-
I forgot to add that this script works on current bash versions on various platforms along with CygWin too.
So replace the word 'deprecated' with 'hidden' until it is completely removed from the bash shell which I suspect will not be for a long while yet...

RBASH(1) General Commands Manual RBASH(1)
NAME
rbash - restricted bash, see bash(1)
RESTRICTED SHELL
If bash is started with the name rbash, or the -r option is supplied at invocation, the shell becomes restricted. A restricted shell is
used to set up an environment more controlled than the standard shell. It behaves identically to bash with the exception that the follow-
ing are disallowed or not performed:
o changing directories with cd
o setting or unsetting the values of SHELL, PATH, ENV, or BASH_ENV
o specifying command names containing /
o specifying a file name containing a / as an argument to the . builtin command
o specifying a filename containing a slash as an argument to the -p option to the hash builtin command
o importing function definitions from the shell environment at startup
o parsing the value of SHELLOPTS from the shell environment at startup
o redirecting output using the >, >|, <>, >&, &>, and >> redirection operators
o using the exec builtin command to replace the shell with another command
o adding or deleting builtin commands with the -f and -d options to the enable builtin command
o using the enable builtin command to enable disabled shell builtins
o specifying the -p option to the command builtin command
o turning off restricted mode with set +r or set +o restricted.
These restrictions are enforced after any startup files are read.
When a command that is found to be a shell script is executed, rbash turns off any restrictions in the shell spawned to execute the script.
