스크립트에서 "^M: 명령을 찾을 수 없음" [중복]

다음 스크립트를 실행하려고합니다.

#!/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

나는 다음과 같은 결과를 얻습니다.

^M: Command not found.
^M: Command not found.

왜 "^M: 명령을 찾을 수 없습니다" 오류가 발생하는지 아시나요?
