Simple script question...

Gene Laoyan — Tue, 05 Dec 2006 02:14:25 GMT

I assign my variable via...
mylog=`hpvmstatus -P scottk_1 | grep scsi`

A typical output from "hpvmstatus -P scottk_1 | grep scsi" gives me the following...
disk scsi 0 0 0 0 0 disk /dev/rdsk/c6t10d0
dvd scsi 0 0 0 1 0 file /tmp/Win2003Server_Itanium-withSP1-AX2EIVOL_EN.iso
disk scsi 0 0 0 2 0 disk /dev/rdsk/c6t10d1

Why does it look like this...
disk scsi 0 0 0 0 0 disk /dev/rdsk/c6t10d0 dvd scsi 0 0 0 1 0 file /tmp/Win2003Server_Itanium-withSP1-AX2EIVOL_EN.iso disk scsi 0 0 0 2
0 disk /dev/rdsk/c6t10d1
when I assign the output to a variable?

I want to keep the formatting and append it after I make a change to the VM's configuration of the disks.

How do I do that?

If you want to keep the formatting, you must put it in a file. You might be able to use sed to change a newline to some other character then change it back just before you print it.

Damn....
I was afraid you'd say that......lol
I guess I'll log to a file instead of build the log into a variable then write it to a text file.

Thanks for your help.

Hi Gene

Try setting IFS to newline before e.g. echoing it:
# mylog=`hpvmstatus -P scottk_1 | grep scsi`
# IFS=\
+
# echo $mylog

Hmm, I can't duplicate your problem. The variable in my case has the embedded newlines and everything seems to work fine.

Hi,

the assignment to the variable does NOT change the formatting! It is the way you do your output.
Formatting preserved:
print "$mylog"

Formatting ignored:
print $mylog
