Question

I try executed some like this

#!/bin/bash
${postid=41930}
while ${postid} < 42000;
do
 `node title.js ${postid}`
  ${postid} = ${postid} +1;
done

I have this error:

: command not found30
run.sh: line 8: syntax error: unexpected end of file

$ echo $SHELL
/bin/bash
$

From man sh

while *list*;do *list*;done

sh version 3.2

There are several places in your script needs to be fixed:

1. As chepner said you can’t assign value to an evaluated result like ${postid}, instead use postid directly in the left hand side of your assignment

2. There should be some invisible characters in your script. Try to run dos2unix myscript.sh or try hand typing the the following code into an new file
