When executing a perl script arguments such as perl_script file arg1 arg2 arg3
generate error messages.

  Can't open arg1​: A file or directory in the path name does not exist\.
  Can't open arg2​: A file or directory in the path name does not exist\.
  Can't open arg3​: A file or directory in the path name does not exist\.

Here is a copy of the script ---

  NV6KNCC cat do\_rshell\.pl
  \#\! /usr/local/bin/perl

  $rcmd = @​ARGV\[0\];

  while\(\<>\) \{
        chomp;
        $R = $\_;
        @&#8203;cmd = \("/u/t01bhjt/do\_router\_rshell"\, $R\, $rcmd\);
        system\(@&#8203;cmd\);
  \}

And what did you expect to get when you tried to open files that don't
exist?

The input operator <>, when used without an explicit filehandle, opens the
files named in @​ARGV in turn. Each element in @​ARGV is treated as a
filename. This is documented in perlop.

It appears that you need correct your script so that it does not treat the
extra arguments as filenames.
