I am unable to run a shell script using ex (VIM)?

Question

$ ex -sc $'%s/\r$//e|x' file Perfectly works from the terminal from but when I try to run it with .sh script it simply ignores the lines after ex.

$ rm ~/Desktop/projectautomate/finalutf81.csv    
$ rm ~/Desktop/projectautomate/finalutf8.csv

$ cat ~/Desktop/projectautomate/headersutf8.csv ~/Desktop/projectautomate/upload.csv >> ~/Desktop/projectautomate/finalutf8.csv


$ iconv -f utf-16 -t utf-8 ~/Desktop/projectautomate/finalutf8.csv -o ~/Desktop/projectautomate/finalutf81.csv -c
$ ex -sc $'%s/\r$//e|x' ~/Desktop/projectautomate/finalutf81.csv

Every thing works but not the last line of command. I am basically trying to remove the CRLF (end line control characters) from the the file finalutf8.csv . Some detailed explanations would be appreciated. If not clear as English is my second language, I would try to explain it.

Answer 1

What are these $ for?

#!/bin/sh
ex -sc '%s/\r//e|x' toto.txt

seems to work the way you want.

Answer 2

$'' is a bash thing only; the shell script is probably being executed with sh or dash. Put

#!/bin/bash

in the first line.
