# rpmalert -h
Usage:
rpmalert -h
rpmalert [ -s ] [ -u ] <upgrade directory>
-h: help --- this message
-s: suppress column headers
-u: attempt upgrade
First we need access to the Red Hat packages and updates. In this example we will mount the Unix Support Red Hat mirror to do this. Note the corresponding unmount at the end of the example.
# mount -o ro nfs-uxsup.csx.cam.ac.uk:/linux/redhat /mnt
Next we find out what packages we need to upgrade on the system, both Intel packages and architecture-neutral packages.
# rpmalert /mnt/updates/6.2/i386 NAME CURRENT UPGRADE ==== ======= ======= e2fsprogs 1.15-3 1.17-1 glib 1.2.5-1 1.2.6-2 groff 1.11a-9 1.15-1 initscripts 4.48-1 4.70-1 linuxconf 1.16r3.2-2 1.16r10-2 pam 0.68-7 0.68-10 sysklogd 1.3.31-12 1.3.31-14 # rpmalert /mnt/updates/6.2/noarch NAME CURRENT UPGRADE ==== ======= =======
We now know that there are no architecture-neutral upgrades needed
so we retstrict attention to the Intel packages and ask
rpmalert to upgrade them. A return code of 0 from the
upgrade means it was completely successful.
# rpmalert -u /mnt/updates/6.2/i386 NAME CURRENT UPGRADE ==== ======= ======= e2fsprogs 1.15-3 1.17-1 glib 1.2.5-1 1.2.6-2 groff 1.11a-9 1.15-1 initscripts 4.48-1 4.70-1 linuxconf 1.16r3.2-2 1.16r10-2 pam 0.68-7 0.68-10 sysklogd 1.3.31-12 1.3.31-14 About to run: rpm --upgrade e2fsprogs-1.17-1.i386.rpm glib-1.2.6-2.i386.rpm groff-1.15-1.i386.rpm initscripts-4.70-1.i386.rpm linuxconf-1.16r10-2.i386.rpm pam-0.68-10.i386.rpm sysklogd-1.3.31-14.i386.rpm Upgrade return code: 0
Finally, if we had to mount a copy of the Red Hat mirror onto
/mnt then we should unmount it again afterwards. Note
that the command is umount and not
unmount.
# umount /mnt
