Crontab command fails but .sh file appears to run 2

[ChrisRChamberlain]

Hi all

Have reinstalled Ubuntu Server 11.04 and have the following crontab command

MAILTO me@mydomain.com
*/5 * * * * /var/data/bin/zoneedit.sh

The file /var/data/bin/zoneedit.sh appears to run in the command window.

The content of zoneedit.sh is

#!/bin/bash

ipfile='/var/data/bin/ipaddress'

[[ -f "$ipfile" ]] && ipold="$(< "$ipfile" )"

ipnew="$( wget -q -O - checkip.dyndns.org | sed -e 's/.*Current IP Address: //;s/<.*$//' )"

if [[ "$ipold" != "$ipnew" ]]; then

  echo "$ipnew" > "$ipfile"

  /usr/sbin/ssmtp me@mydomain.com < /var/[URL unfurl="true"]www/ipaddress[/URL] 

  wget -O - --http-user=Me --http-passwd=Password '[URL unfurl="true"]http://dynamic.zoneedit.com/auth/dynamic.html?host=www.mydomain.com'[/URL]

  wget -O - --http-user=Me --http-passwd=Password '[URL unfurl="true"]http://dynamic.zoneedit.com/auth/dynamic.html?host=mydomain.com'[/URL]

fi

As far as I know, the code is exactly as was before reinstalling. The file /var/data/bin/ipaddress exists and even if IP address in the file is the current external IP address it still fails, so the error is not in the second half of the program.

The ownership of the folder/files etc is mine.

The error message emailed is

/bin/sh: /var/data/bin/zoneedit.sh: not found

TIA

Just to clarify, the following code with correct details from the second half of the .sh file executes as expected.

wget -O - --http-user=Me --http-passwd=Password '[URL unfurl="true"]http://dynamic.zoneedit.com/auth/dynamic.html?host=www.mydomain.com'[/URL]

wget -O - --http-user=Me --http-passwd=Password '[URL unfurl="true"]http://dynamic.zoneedit.com/auth/dynamic.html?host=mydomain.com'[/URL]

...and if you try to run

/var/data/bin/zoneedit.sh

from the terminal, the error is

bash: /var/data/bin/zoneedit.sh: //bin/bash^M: bad interpreter: No such file or directory

The earlier comments concerning running the file related to directly executing the file in the folder /var/data/bin/

Hi

bash: /var/data/bin/zoneedit.sh: //bin/bash^M: bad interpreter: No such file or directory

Now that says it all : the script was copied over to a Windows machine and the file got DOS end-of-line marks.

So clean it up with :

dos2unix /var/data/bin/zoneedit.sh

[gray]# or[/gray]

sed -i 's/\r$//' /var/data/bin/zoneedit.sh

Or just run it as :

bash /var/data/bin/zoneedit.sh
