Question

I have been trying to run Linux shell script on Windows machine. to run the script on windows environment, i have selected Cygwin.

when i first started running the script using cygwin, i first faced following issue.

line 12: $'\r': command not found

but line number 12 does not have any command

  08  #
  09  ######################################################################
  10  #### PARAMETERS TO SET BEGIN
  11  ######################################################################
  12  
  13  # archive setttings
  14  ARCHIVE_USER=abc                      # archive storage user name  (default)
  15  ARCHIVE_GROUP=app                     # archive storage user group (default)
  16  ARCHIVE_PATH=/test/file               # archive storage directory (default)
  17  ARCHIVE_DELAY=+8

To solve this issue used dos2unix command and generated new shell scrip from the old one

when i run this newly generated scrip it again returns an error

housekeeper.sh: 2: Syntax error: newline unexpected

following is the dos2unix generated script.

>#!/bin/bash
>>#
>># Date  : 2012-03-22 (yyyy-mm-dd)

could somebody explain me what is wrong with the line number2 here.

thanks in advance for any help

Following is top of the script i am trying to run , this is the script i get after converting using dos2unix command

>#!/bin/bash
>>#
>># Date  : 2012-03-22 (yyyy-mm-dd)
>># Modified by   : ABC
>># Goal          : Draft version for X house keeping environment

Answer 1

That sounds like a line termination issue (Windows uses Carriage Return, Linefeed and Unix uses just Linefeed). You can correct these issues using dos2unix (and unix2dos), which converts the line terminators.

Try:

$ dos2unix myscript.sh
