I am trying to run the following script.

#!/bin/csh
# USAGE EXAMPLE: solve_mysteries.scr ops6.txt 2
# USAGE EXAMPLE: solve_mysteries.scr allops.txt 1800
set opsfile = $1
set maxtime = $2
set f = $3

set outfile = brute_solutions.dat
set outfile2 = brute_constant.dat
set outfile3 = brute_formulas.dat
if -f $outfile /bin/rm $outfile
if -f $outfile2 /bin/rm $outfile2
if -f $outfile3 /bin/rm $outfile3

echo Trying to solve mysteries with brute force...

echo Trying to solve $f...
echo /bin/cp -p $f mystery.dat
/bin/cp -p $f mystery.dat
echo $opsfile arity2templates.txt mystery.dat results.dat >args.dat

timeout {$maxtime}s ./symbolic_regress3.x

I get the following output

^M: Command not found.
^M: Command not found.
Trying to solve mysteries with brute force...
^M: Command not found.
...ing to solve ../example_data/example2.txt_train
 mystery.dat./example_data/example2.txt_train
/bin/cp: cannot stat '../example_data/example2.txt_train'$'\r': No such file or directory
^M: Command not found.
timeout: invalid time interval ‘60\rs’
Try 'timeout --help' for more information.
^M: Command not found.

Any idea why I am getting this "^M: command not found" error?

cat -v script shows you that at least some of the lines have a CR (carriage return) character, probably at the end.

Your script is a text file in DOS/Windows format. You need to convert it to Unix format (i.e. remove the CRs). This can be done by editors or e.g. the tool dos2unix.

If you can download Sublimetext, which is an text editor, you can change the line endings from View->LineEndings->Unix

Then save the file and try running it again.
