Hello everybody,
This is my first post on this list ...
Currently I try to learn Perl language ...
I want to rewrite a Korn Shell script wich is make a full system backup,
by using the system tools available under Solaris 8: fssnap/ufsdump
The Korn Shell script does the following tasks:
1. The snapshot path is stored in the SnapRoot variable:
SnapRoot=$(fssnap -F ufs -o backing-store=/home/SNAP /)
Value for SnapRoot is now, for example: /dev/fssnap/3
Return value for fssnap command is tested by :
SnapRoot=$(fssnap -F ufs -o backing-store=/home/SNAP /)
if (( $? != 0 ))
then
print "Erreur dans la creation du snapshot pour: /" >> $LOGFILE
cat $LOGFILE | mailx -s "$SubjectAlarm" $MAILDEST
exit 1
fi
2. Dump is made directly on a tape:
ufsdump 0f /dev/rmt/0n $SnapRoot
Return value for ufsdump is tested too :
ufsdump 0f /dev/rmt/0n $SnapRoot
if (( $? != 0 ))
...
...
My perl script try to do the same things ... but :
I need to do that, (like for my shell-script) to get the value of the
path
of my snapshot in the SnapRoot variable:
my $SnapRoot =`fssnap -F ufs -o backing-store=/home/SNAP /` ;
If I try to use the perl system function:
my $SnapRoot=system("fssnap -F ufs -o backing-store=/home/SNAP /");
SnapRoot variable will be filled by the return status from system( ).
I need to get return status for the fssnap command AND its value
(in my example: /dev/fssnap/3 ).
if ( ( system("fssnap ...") ) )
{
....
}
For testing the return value for this command that's ok but I would
like
to store the backup path in the SnapRoot variable ...
How to do that ?
If we need instruction like:
my $SnapRoot =`fssnap -F ufs -o backing-store=/home/SNAP /` ;
(using backstits) I don't know where is the benefice to use perl instead
of shell scripts for theses tasks...
Thank for your help and have a nice day !
