There's the handy
Newer command in MorphOS. It compares version strings found in two files, so if you have a file containing a version string ("$VER: Wayfarer 3.8", for example), you can compare that against the actual executable file.
You could have a separate version file like "https://www.morphos-storage/network/web/wayserver.version", but why not add a version string into "https://www.morphos-storage/network/web/wayfarer.install" and you could go with one download for both version checking and installing.
Here's example(s):
Code:
; Set files here, no need to modify rest of the code then:
Set LOCALFILE "SYS:Applications/Wayfarer/Wayfarer"
Set REMOTEURL "https://jpv.amigaaa.com/"
Set REMOTEFILE "wayserver.version"
; Examples for testing newer and older version strings:
;Set REMOTEFILE "wayserver.version_old"
;Set REMOTEFILE "wayserver.version_new"
; If the wayfarer.install file would include a version string (no need for a separate version file):
;Set REMOTEURL "https://www.morphos-storage.net/network/web/"
;Set REMOTEFILE "wayfarer.install"
; The actual script:
FailAt 21 ; Don't stop execution on fails, but handle them in the script.
wget -q --no-check-certificate -O "RAM:$REMOTEFILE" $REMOTEURL$REMOTEFILE
Newer "$LOCALFILE" "RAM:$REMOTEFILE"
Set NEWRC $RC
If $NEWRC EQ 5
Echo "Remote is newer!"
Else
If $NEWRC GE 10
Echo "Can't check the version!"
Else
Echo "Remote is not newer."
EndIf
EndIf
Unset NEWRC
Unset REMOTEFILE
Unset REMOTEURL
Unset LOCALFILE
