Syntax error near unexpected token ' newline ' script cannot be executed

Problem description

Execute run.sh script is an error, the error message is as follows:

/data/app/information-provider
: No such file or directory
: command not found
./run.sh:line 4:syntax Error Near unexpected token ' newline '
/run.sh:line 4: ' Case ' $ ' in  

Problem analysis

Find the script, there is no problem with the script, so I suspect that the file format is not correct.
View the file by following the command

Cat-a run.sh

Found in run.sh, line wrap ends with ^m$

Server= "$ (dirname" ${bash_source[0]} ")" && pwd ^m$
cd $server ^m$ ^m$ case
"$" in  ^m$
  ^ m$ ...
  

Solutions

Execute the following statement to convert run.sh to a new line character in the Linux environment $

Dos2unix run.sh

View the transform file by Cat-a run.sh as:

Server= "$ (dirname" ${bash_source[0]} ")" && pwd $
CD $server $
$ case
"$"
