script output different when cron runs it

aristosv · 06-28-2015, 11:27 PM

When I manually run the script below, the output is just the way I want it. When cron runs it, I get like fifty of these ::::::::: in the output of the script.

Is there any chance cron is doing something different when running the script? Any way I can get additional information that will help me troubleshoot the issue?

crontab -e

Code:

@daily /root/daily

/root/daily

Code:

#!/bin/bash
#Import Variables
source /root/config/variables
#Random Delay
/bin/sleep $((RANDOM$delayreboot))
#Run Daily
/root/start

Which distro and which version of cron?

aristosv · 06-29-2015, 12:14 AM

I'm running raspbian, but I couldn't find a way to get the cron version..

cat /etc/*-release

Code:

PRETTY_NAME="Raspbian GNU/Linux 7 (wheezy)"
NAME="Raspbian GNU/Linux"
VERSION_ID="7"
VERSION="7 (wheezy)"
ID=raspbian
ID_LIKE=debian
ANSI_COLOR="1;31"
HOME_URL="http://www.raspbian.org/"
SUPPORT_URL="http://www.raspbian.org/RaspbianForums"
BUG_REPORT_URL="http://www.raspbian.org/RaspbianBugs"

cron --version?

aristosv · 06-29-2015, 12:20 AM

No, not working. I've also googled it and tried to find other ways but nothing works. Cron is running though that's for sure.

cron --version

Code:

cron: invalid option -- '-'
usage: cron

Which image?

aristosv · 06-29-2015, 02:35 AM

I am using the image that was released on 2015-02-16
Its the previous one from the current.

It's difficult to say since you haven't showed us what's in /root/config/variables or /root/start.

And what script output are you referring to? You don't have anything going to a log file in what you've shown.

n/m. Sorry.

start

Code:

#!/bin/bash
/root/config/commands 2>&1 > /root/log/$HOSTNAME.log

commands

Code:

#!/bin/bash
#Set Variables
source /root/config/variables
#Download Media
/bin/echo "Sync $(/usr/bin/lftp ftp://$ftpuser:$ftppass@$ftphost -e "set ftp:ssl-allow no ; set net:reconnect-interval-base 5 ; set net:max-retries 2 ; mirror -e $remotemedia $localmedia ; quit")"

variables

Code:

#!/bin/bash
#Set Variables
export ftpuser="user_name_here"
export ftphost="ftp_host_here"
export ftppass="pass_here"
export remotemedia="/name/music"
export localmedia="/root/media"

My guess is it has to do with your nested double quotes in commands (not a terrific name for a script BTW). Does anything change if you switch the inside pair to single quotes?

aristosv · 06-30-2015, 12:02 AM

this is the result

Code:

::::::::::::::
/root/log/Client38.log
::::::::::::::
Sync

when in fact after the word "Sync" there should be the results of the synchronization process.
