profileuser, I have refrained from giving you a fifth warning for code tags so far because any more warning points would set your account read-only for a month. Please at least try.

Moderator's Comments:
Mod Comment To keep the forums high quality for all users, please take the time to format your posts correctly.

First of all, use Code Tags when you post any code or data samples so others can easily read your code. You can easily do this by highlighting your code and then clicking on the # in the editing menu. (You can also type code tags [code] and [/code] by hand.)



Second, avoid adding color or different fonts and font size to your posts. Selective use of color to highlight a single word or phrase can be useful at times, but using color, in general, makes the forums harder to read, especially bright colors like red.

Third, be careful when you cut-and-paste, edit any odd characters and make sure all links are working property.

Thank You.

Hi Guys,

Could you please help diagnose the syntax the script below is refering:

Code:
[root@xen01 ~]# vi ./postscript.sh
[root@xen01 ~]# ./postscript.sh
-bash: ./postscript.sh: Permission denied
[root@xen01 ~]# chmod 755 ./postscript.sh
[root@xen01 ~]# ./postscript.sh
./postscript.sh: line 5: if[ -a /tmp/secondboot ]: No such file or directory
./postscript.sh: line 6: syntax error near unexpected token `then'
./postscript.sh: line 6: `then'
[root@xen01 ~]#

The full script written in vi is below:

Code:
[root@xen01 ~]# vi ./postscript.sh
#!/bin/bash
# Install XenServer Updates
HOSTUUID=$(xe host-list name-label=$HOSTNAME --minimal)
cd /tmp
if[ -a /tmp/secondboot ]
then
        echo "Secondboot"
else
        mkdir updates
        cd updates
        echo"Downloading updates..."
        wget ftp://192.168.10.5/FTP/xen62/*.xsupdate
        cd /tmp
        touch /tmp/secondboot
fi
for updatefile in 'ls /tmp/updates';do
        echo sleeping in 60 secs
        sleep 60
        echo "Uploading Update $updatefile..."
        echo "Uploading Update $Updatefile...">> /var/log/messages
        PATCHUUID=$(xe patch-upload file-name=/tmp/Updates/$updatefile)
        sleep 10
        echo "installing Update $updatefile..."
        echo "installing update $updatefile...">> /var/log/messages
        xe patch-apply host-uuid=$HOSTUUID uuid=$PATCHUUID
        rm -f /tmp/updates/$updatefile
        PATCHACTION=$(xe patch-list uuid=$PATCHUUID params=after-apply-guidance --minimal)
        if[ "$PATCHACTION"=="restartXAPI" ]
then
        /opt/xensource/bin/xe-toolstack-restart
        sleep 60
elif [ "$PATCHACTION"=="restartHost" ]; then
        reboot;
        sleep 60
fi
done
# Disable first boot for subsequent reboots
rm -f /etc/rc3.d/S99zzpostinstall
rm -f /tmp/secondboot
# Final Reboot
reboot

Hi Guys,

what file or directory is it referring ?

syntax near unexpected token; what does this mean ?
# 18  
Old 04-01-2014
Give space after "if" statement

Code:
if [ -a /tmp/secondboot ]

Hi Npandith,

You did it,

The last syntax error given now is the 'then' on line 29', what does this mean ?

So apparently, the script has downloaded the updates however it has not applied the patched yet.

seems a long way to go yet in trouble shooting this script in order to apply the patches to the server.

Please assist whereever you can

Code:
 PATCHACTION=$(xe patch-list uuid=$PATCHUUID params=after-apply-guidance --minimal) 
if  [ "$PATCHACTION"=="restartXAPI" ]
then
        /opt/xensource/bin/xe-toolstack-restart
        sleep 60
elif [ "$PATCHACTION"=="restartHost" ]; then
        reboot;
        sleep 60
fi
done

Add spaces:

Now:
Code:
if[ "$PATCHACTION"=="restartXAPI" ]

After:
Code:
if [ "$PATCHACTION" == "restartXAPI" ]


EDIT:
VBS was faster typing Smilie
BTW: Same goes for the ELIF below.
