Insight Guide How to customise centmin.sh option 22 wordpress routines & keep changes?

By design in Centmin Mod 123.09beta01, when you update Centmin Mod code via cmupdate command, a git stash/refresh of the latest Centmin Mod code on github.com is pulled to /usr/local/src/centminmod/ directory. So if you happen to modify your centmin.sh menu option 22 wordpress routine code which is contained in /usr/local/src/centminmod/inc/wpsetup.inc include file, those changes are reset/wiped on cmupdate command.

---

However, as a workaround for now, you can automatically put in place your custom changes to /usr/local/src/centminmod/inc/wpsetup.inc using a custom mycmupdate command file you create below:

First, backup any changes and customisations you did to your existing /usr/local/src/centminmod/inc/wpsetup.inc if any.

Second, do a cmupdate which will resetup/wipe /usr/local/src/centminmod/inc/wpsetup.inc

Code (Text):

cmupdate

then make a copy of the latest /usr/local/src/centminmod/inc/wpsetup.inc include file as /usr/local/src/centminmod/inc/wpsetup-custom.inc

Code (Text):

\cp -f /usr/local/src/centminmod/inc/wpsetup.inc /usr/local/src/centminmod/inc/wpsetup-custom.inc

make all your customisations in the copied include file at /usr/local/src/centminmod/inc/wpsetup-custom.inc bringing over any changes you backed up previously

then override the default /usr/local/src/centminmod/inc/wpsetup.inc with yours /usr/local/src/centminmod/inc/wpsetup-custom.inc

Code (Text):

\cp -f /usr/local/src/centminmod/inc/wpsetup-custom.inc /usr/local/src/centminmod/inc/wpsetup.inc

now whenever you do cmupdate that will be overriden but you can then override it again with your /usr/local/src/centminmod/inc/wpsetup-custom.inc

Code (Text):

cmupdate
\cp -f /usr/local/src/centminmod/inc/wpsetup-custom.inc /usr/local/src/centminmod/inc/wpsetup.inc

then create your own cmupdate command as mycmupdate as cmupdate is just a symlink by creating file using touch command making it executable

Code (Text):

touch /usr/local/bin/mycmupdate
chmod +x /usr/local/bin/mycmupdate

then use vim/nano editors to edit /usr/local/bin/mycmupdate and just place in the following code

Code (Text):

#!/bin/bash
cmupdate
echo
echo "diff"
sdiff -s /usr/local/src/centminmod/inc/wpsetup.inc /usr/local/src/centminmod/inc/wpsetup-custom.inc
echo
\cp -f /usr/local/src/centminmod/inc/wpsetup-custom.inc /usr/local/src/centminmod/inc/wpsetup.inc
echo "done"

or if you prefer diff -u command instead of sdiff -s

Code (Text):

#!/bin/bash
cmupdate
echo
echo "diff"
diff -u /usr/local/src/centminmod/inc/wpsetup.inc /usr/local/src/centminmod/inc/wpsetup-custom.inc
echo
\cp -f /usr/local/src/centminmod/inc/wpsetup-custom.inc /usr/local/src/centminmod/inc/wpsetup.inc
echo "done"

it basically is a script to run cmupdate, then do a side by side comparison diff of original vs custom wpsetup-custom.inc files and then run copy command unaliased with forced override to use your custom version

example run for mycmupdate command in SSH with sdiff -s

You can use the sdiff/diff to judge for yourself any changes in the latest default wpsetup.inc that need migrating over to your custom wpsetup-custom.inc manually after running mycmupdate
