I'm getting the strangest behavior in my script. I can echo the line in the script and that works fine. I see the output as I would expect. However on some lines (and the file doesn't have any strange characters in it) when I use that $line variable in a command, some characters are being replaced with spaces. Here is the code:
Code:
#!/bin/bash
set -x
file="vms.txt"
while read line
do
echo "Line: $line"
if VBoxManage list vms | grep \"$line\" > /dev/null 2>&1
then
echo "Found VM: $line"
VMS=$(VBoxManage showvminfo ${line} | grep "State:")
echo $VMS
else
echo "Virtual Machine Not found: $line"
fi
done <"${file}"
...but here is the output with the set -x on:
Code:
Found VM: DebianSQL
+ VBoxManage showvminfo DebianSQL
+ grep State:
+ VMS=State: aborted (since 2013-01-14T04:54:26.000000000)
+ echo S a e: abor ed ( ince 2013-01-14T04:54:26 000000000)
S a e: abor ed ( ince 2013-01-14T04:54:26 000000000)
+ read line
+ echo Line: DebianMC
Line: DebianMC
+ VBoxManage list vms
+ grep "DebianMC"
+ echo Found VM: DebianMC
Found VM: DebianMC
+ VBoxManage showvminfo DebianMC
+ grep State:
+ VMS=State: running (since 2013-03-02T17:23:13.831000000)
+ echo S a e: running ( ince 2013-03-02T17:23:13 831000000)
S a e: running ( ince 2013-03-02T17:23:13 831000000)
+ read line
+ echo Line: DebianTemplate
Line: DebianTemplate
+ VBoxManage list vms
+ grep "DebianTe pla e"
+ echo Virtual Machine Not found: DebianTemplate
Virtual Machine Not found: DebianTemplate
+ read line
SO you can see with the highlighted items, I'm getting some strange output. I tried setting the engine from /bin/bash and /bin/sh and that didn't make any difference.
Any idea what is causing this? I know the "DebianTemplate" is there, but when I grep with the variable set to that, somehow there is character substitution going on and the spaces make it look like a different VM name.
