BSD, Linux, and UNIX systems shells expect the script that they read to be text files consisting of zero or more lines each line of which is terminated by a <newline> character. At least the first line in your script is terminated by a <carriage-return><newline> character pair which is what one would expect in a DOS/Windows text file. The error message is telling you that your operating system can't find a file named /bin/bash<carriage-return> (where <carriage-return> is the ASCII <CR> carriage return character).
Please get rid of the <carriage-return> characters in your script, and try running it again.

__________________________________________________________________________________________________________________________________________________
NAME
tclsh - Simple shell containing Tcl interpreter
SYNOPSIS
tclsh ?-encoding name? ?fileName arg arg ...?
_________________________________________________________________
DESCRIPTION
Tclsh is a shell-like application that reads Tcl commands from its standard input or from a file and evaluates them. If invoked with no
arguments then it runs interactively, reading Tcl commands from standard input and printing command results and error messages to standard
output. It runs until the exit command is invoked or until it reaches end-of-file on its standard input. If there exists a file .tclshrc
(or tclshrc.tcl on the Windows platforms) in the home directory of the user, interactive tclsh evaluates the file as a Tcl script just
before reading the first command from standard input.
SCRIPT FILES
If tclsh is invoked with arguments then the first few arguments specify the name of a script file, and, optionally, the encoding of the |
text data stored in that script file. Any additional arguments are made available to the script as variables (see below). Instead of
reading commands from standard input tclsh will read Tcl commands from the named file; tclsh will exit when it reaches the end of the
file. The end of the file may be marked either by the physical end of the medium, or by the character, "
