So I'm trying to get amverify to verify "nttar" and "gtar" backups.
I've looked at this part of the amverify script from amanda 2.4.2p2:

if [ X"$1" = X"program" -a X"$2" != X"" ]; then
        if [ X"$TAR" != X"" -a X"$2" = X"$TAR" ]; then
                CMD=$TAR
                ARGS="tf -"
        elif [ X"$TAR" != X"" \
                -a X"$SAMBA_CLIENT" != X"" \
                -a X"$2" = X"$SAMBA_CLIENT" ]; then
                CMD=$TAR
                ARGS="tf -"
        elif [ X"$TAR" != X"" \
                -a X`basename $2` = X`basename $TAR` ]; then
                CMD=$TAR
                ARGS="tf -"

But I don't understand it. If $1 is "tar", oes X"$1" = X"program"
compare "Xtar" to "Xprogram"? What are all these X's for?
