Script showing bad interpreter and will not run

Question

I was sent a perl script over mail and asked to run it .I placed it on my local drive as is but when I tried to run the script it shows me

/usr/bin/perl^M: bad          


        

Answer 1

You're on the right track. Your script has DOS style newlines at the end, which is not supported by your kernel.

The solution is to use something to convert the DOS newlines to Unix style. dos2unix would presumably work if you had it, so use something else equivalent.
