Run the shell script prompt to find the file error, workaround

Sometimes run a shell script error, generally can not find the shell file, mostly because the script is generated under Windows and then copy to Linux, with the following command check:

$ head-1 Yourscript | Od-c

And the IT ends:this is wrong

0000000   #   !   /   b   i   n   /   b   a   s   H  \ r  \ n

This is correct:

0000000   #   !   /   b   i   n   /   b   a   s   h  \ n

Use Dos2unix to fix your The script if it is the issue.

If the above problem occurs, run the following command directly: Dos2unix filename
