Below are the instructions from the Slack site about upgradepkg. Something
I've always wanted to know: was is meant by "same name"

I did upgradepkg automake-1.8.5-noarch-1.tgz. It worked. Does the installer
only look for the name "automake"? How does upgradepkg know whether you have
"name" already installed?

I've looked EVERYWHERE for where the "name" is defined. Anyone know?

Upgrades a currently installed package with the package specified. If the
packages have the same name, then you only need to run upgradepkg packagename
to perform the upgrade. If the new package has a different name than the
currently installed package, you must use this syntax:

upgradepkg oldpackagename%newpackagename

Slackware pkgtools looks at
- - /var/adm/packages for the currently installed packages,
- - /var/adm/scripts for the install scripts for the currently installed
packages,
- - /var/adm/removed_packages for the packages removed or replaced, and
- - /var/adm/removed_scripts for the removal scripts for removed packages

Er, yes, and what exactly has that got to do with the question?

The OP was asking what upgradepkg regards as the name of a package, is
it the whole name of the tgz file (automake-1.8.5-noarch-1.tgz), is it
just the application name (automake) or what is it?

I seem to remember I had exactly this problem a while ago and I don't
think I ever found out what the answer was either.

well, the answer, of course, is in upgradepkg itself. it's just a shell
script, so you can view it:

#v+

# Here's a function to figure out the package name from one of those
# new long filenames. We'll need this to double check the name of the
# old package.

package_name() {
STRING=`basename $1 .tgz`
# Check for old style package name with one segment:
if [ "`echo $STRING | cut -f 1 -d -`" = "`echo $STRING | cut -f 2 -d -`" ]; then
echo $STRING
else # has more than one dash delimited segment
# Count number of segments:
INDEX=1
while [ ! "`echo $STRING | cut -f $INDEX -d -`" = "" ]; do
INDEX=`expr $INDEX + 1`
done
INDEX=`expr $INDEX - 1` # don't include the null value
# If we don't have four segments, return the old-style (or out of spec) package name:
if [ "$INDEX" = "2" -o "$INDEX" = "3" ]; then
echo $STRING
else # we have four or more segments, so we'll consider this a new-style name:
NAME=`expr $INDEX - 3`
NAME="`echo $STRING | cut -f 1-$NAME -d -`"
echo $NAME
# cruft for later
#VER=`expr $INDEX - 2`
#VER="`echo $STRING | cut -f $VER -d -`"
#ARCH=`expr $INDEX - 1`
#ARCH="`echo $STRING | cut -f $ARCH -d -`"
#BUILD="`echo $STRING | cut -f $INDEX -d -`"
fi
fi
}

#v-

essentially what it comes down to is that the last three segments of a
package name, the program version number, architecture and the package
version number, are discarded. i.e., if you have a package such as
yaboot-1.3.6-powerpc-1, the package name for upgradepkg is yaboot; if you
have a package such as xfce4-xkb-plugin-0.3.1-powerpc-2, the package name
is xfce4-xkb-plugin.

I'm not sure if anybody else has mentioned this already but the
"same name" probably comes about because prior to Slackware 8.1 each
package was named as an 8.3 file name - eg glibcso.tgz
rather than glibc-solibs-2.32-i486-1.tgz

If you were upgrading from an old 'short' (8.3) named package to a new
'long' name package, you'd do:
upgradepkg glibcso%glibc-solibs-2.32-i486-1.tgz

Ahhh. Nothing, I guess

Chalk it up to an insomniac's half-awake ramblings @ 1:30 AM

Sorry
