cannot execute binary file, though ownership and permissions are set correctly :(


Any suggestions, please?

This whole backup issue is bugging me for days and I can't get it working :'(

I want to use a script to do an automated backup of another machine using rsync.

Part of the problems I have is that if I try to rund the script it won't run:
cannot execute binary file

Ownership and permissions are set correctly
The User that should execute it has rx (500) on it. But neither he nor root can run it.

Here is the script:

Code:
#!/bin/bash
#
# Script zieht per rsync Backups
# http://www.heinlein-partner.de
#
# Aufruf: backup-rsync <fqdn-servername>
#

# ### Aufrufparameter des Scripts ist ein FQDN-Hostname
if [ -n "$1" ] ; then
	SERVER="$1"
else
	echo "Error: Usage $0 <fqdn-hostname>"
	exit
fi
	


# ### Konfiguration
# Sollen wir pruefen, ob noch ein gewisser Prozentsatz 
# an Plattenplatz und Inodes frei ist?
CHECK_HDMINFREE=true
HDMINFREE=90

# Soll die Daten-Partition readonly gemountet werden, 
# wenn wir sie nicht mehr brauchen?
MOUNT_RO=false
MOUNT_DEVICE=/dev/hda7

# Unter welchem Pfad wird gesichert?
DATA_PATH=/DATA

# Liste von Dateipattern, die nicht gebackupt werden sollen
EXCLUDES=/etc/rsync-excludelist

# Weitere Optionen für rsync. Ggf. macht eine Limitierung 
# der Bandbreite Sinn, Angabe in kbyte/sec:
# EXTRAOPT="--bwlimit=256"
EXTRAOPT=""


# ### Let´s Rock`n`Roll

# Pruefe auf freien Plattenplatz
GETPERCENTAGE='s/.* \([0-9]\{1,3\}\)%.*/\1/'
if $CHECK_HDMINFREE ; then
	KBISFREE=`df /$DATA_PATH | tail -n1 | sed -e "$GETPERCENTAGE"`
	INODEISFREE=`df -i /$DATA_PATH | tail -n1 | sed -e "$GETPERCENTAGE"`
	if [ $KBISFREE -ge $HDMINFREE -o $INODEISFREE -ge $HDMINFREE ] ; then
		echo "Fatal: Not enough space left for rsyncing backups!"
		logger "Fatal: Not enough space left for rsyncing backups!"
		exit
	fi
fi

# Festplatte rw remounten falls gewünscht!
if $MOUNT_RO ; then
        if `mount -o remount,rw $MOUNT_DEVICE $DATA_PATH` ; then
                echo "Error: Could not remount $MOUNT_DEV readwrite"
                logger "Error: Could not remount $MOUNT_DEV readwrite"
                exit
        fi
fi

# Ggf. Verzeichnis anlegen
if ! [ -d $DATA_PATH/$SERVER/daily.0 ] ; then
        mkdir -p $DATA_PATH/$SERVER/daily.0
fi

# Los geht`s: rsync zieht ein Vollbackup
echo "Starting rsync backup from $SERVER..."
logger "Starting rsync backup from $SERVER..."

rsync  -avz --numeric-ids -e ssh --delete --delete-excluded   \
        --exclude-from="$EXCLUDES"  $EXTRAOPT                   \
        $SERVER:/ $DATA_PATH/$SERVER/daily.0

# Rückgabewert prüfen.
# 0 = fehlerfrei, 
# 24 ist harmlos; tritt auf, wenn während der Laufzeit
# von rsync noch (/tmp?) Dateien verändert oder gelöscht wurden.
# Alles andere ist fatal -- siehe man (1) rsync
if ! [ $? = 24 -o $? = 0 ] ; then
	echo "Fatal: rsync finished $SERVER with errors!"
	logger "Fatal: rsync finished $SERVER with errors!"
fi

# Verzeichnis anfassen, um Backup-Datum zu speichern
touch $DATA_PATH/$SERVER/daily.0

# Fertig!
echo "Finished rsync backup from $SERVER..."
logger "Finished rsync backup from $SERVER..."

# Sicher ist sicher...
sync

# Festplatte ro remounten falls gewünscht!
if $MOUNT_RO ; then
        if `mount -o remount,ro $MOUNT_DEVICE $DATA_PATH` ; then
                echo "Error: Could not remount $MOUNT_DEV readonly"
                logger "Error: Could not remount $MOUNT_DEV readonly"
                exit
        fi
fi

I tried it w/o success on a Suse 9.3 distrib (i586 OS on Opteron CPU) and Suse 10.0 (i586 OS on Athlon CPU).

What is the Prob here?


btw I am neither a newbee nor a linux pro, so please, if you suggest to take a certain action also mention how

It could just be the Advanced Bash-Scripting Guide but I don't see a test for the lower case n (-n) at:
Quote:
if [ -n "$1" ] ; then
SERVER="$1"
however there is one for the uppercase -N

thats already too much for me, plz specify

What could I do to get it running?

btw I did not write the script. It should be nothing wrong with it. It is from a tutorial and has been tested before. If there was just a mistake in the script it would have been found by now I assume.

xjlittle: check the manpage for bash, it's in there.

rahmmandel:
Where is the file located?
What are you typing on the commandline to run the file?
Is "cannot execute binary file" the exact output after you run it?

Thank you for your answer

The script is named backup-rsync
and is located in /home/user_who_runs_it/backup/

when trying to run it I enter the complete path
/home/user_who_runs_it/backup/backup-rsync
or a relative one like ./backup/backup-rsync if I already am in the home directory of that user

I (auto)complete my commands using the tab key, so he dirs and files actually exist

The exact output is:
-bash: path/I/entered/backup-rsync: cannot execute binary file

Do you have /home on a seperate partition? Please check the mount options for the partition where it is. Do you see something like "noexec" in this line? If yes change the appopriate line in /etc/fstab to include the "exec" option for this partition. See "man mount" if you want to know about this (in my manpage version type "/defaults" after invoking man and you will jump to these options).

Gosch I just fixed that crap

First of all, thanks to you guys for your thoughts!

But, it was the script. I found it on another site and compared it to the one I already had (using ultraedit under win).
It turned out that there was one single character in the first line to be found before
#!/bin/bash

It was never displayed though. Neither using Linux nor Windows!!
Couldn't delete it under Win either. But under Linux it worked.
Too weird for me, sorry

I still am afraid I am going to be back soon with the issues concerning rsync
