Istruzioni bash per ritornare più di un valore

[kruskaiev]

Ti posto una funzione che avevo fatto io che inizializza un array e poi lo scorre.

# Show information about partitions (SHOW 0.2rc2)
disk () {
    DEV=`df | grep /dev  | awk {'print $1'}`      # devices presents on df
    NUM_DEVICES=`df | grep /dev | wc -l`          # number of devices presents on df
    HDDTEMP=`which hddtemp`                       # path of hddtemp binary
    #Show partitions
    echo -e "---- Mounted Partitions ----"
    for d in $DEV;
    do
        device=( "${device[@]}" $DEV )            # create array with devices presents on df
    done
    for (( x=0; x<$NUM_DEVICES; x++ ))
    do
        for i in ${device[$x]};
        do
            if [ -b "$i" ]; then
                echo -e "|_ Partitions: `basename $i`"
                echo -e "  \\_"
                echo -e "    |_ Size: `df -h | grep $i | awk {'print $2'}`"
                echo -e "    |_ Used: `df -h | grep $i | awk {'print $3'}` (`df | grep $i | awk {'print $5'}`)"
                echo -e "    |_ Available: `df -h | grep $i | awk {'print $4'}`"
                echo -e "    |_ Mount Point: `df | grep $i | awk {'print $6'}`"
                echo -e "    |_ Filesystem: `mount | grep $i | awk {'print $5'}`"
                echo -e "    |_ Options: `mount | grep $i | awk {'print $6'} | sed {s/\(//g} | sed {s/\)//g}`"
                if [[ -f $HDDTEMP ]]; then          # if hddtemp is installed
                    SENSOR=`${HDDTEMP} $i | awk {'print $5$6$7'}`
                    if [ "$SENSOR" = "S.M.A.R.T.notavailable" ]; then
                        echo -e "    |_ Temperature: not available"
                    else
                        echo -e "    |_ Temperature: `${HDDTEMP} ${device[$x]} | grep /dev | awk {'print $5'}` "
                    fi;
                else
                    echo -e "    |_ Info: install hddtemp for temperature monitoring"
                fi;
                echo ""
            fi;
        done
    done
}
