Hello, I try to initialyze the key'hash :
my %Slices ; open( FH_DF, system( "df -k -F ufs | cut -c 56-100" ) ) ; while ( <FH_DF> ) { $Slices{$key} = '$_' ; } Output will be like that : / /usr /home /opt That don't work correctly ... I need first to initialize the key and in a second loop the backup path. Is it possible ? for example, second loop : while ($key) = each %Slice ) { $Slice{$value} = `fssnap -i $key | grep /dev/fssnap | cut -c 33-45` ; } What is wrong ?
