[Solved] centmin.sh takes up 100% when forced termination

which centmin.sh menu option ?

i take it, this is with centmin command and not via

Code (Text):

cmdir
./centmin.sh

try with these 2 commands and see if it happens

also which SSH client app you using to log into server ? does same problem happen if you use a different SSH client app ?

 

ctrl+z or ctrl+c ?

ctrl+z puts script in background instead of terminating the script https://askubuntu.com/questions/510...nce-between-ctrl-z-and-ctrl-c-in-the-terminal

so right command should be ctrl+c not ctrl+z to terminate centmin.sh

 

when / at what stage in centmin.sh menu option 5 process are you hitting ctrl+c ? I have used ctrl+c to abort centmin.sh menu option 5 mid run without such high loads as centmin.sh has the code to abort ctrl+c when detected

which SSH client app you using to log into server ? does same problem happen if you use a different SSH client app ?

if you have done multiple ctrl+z runs, you could of left some background centmin.sh in place and that is what you're seeing the load from ?

 

from https://askubuntu.com/a/510816

I use SecureCRT and ctrl+c for me in either menu option 4 or 5 will terminate to SSH command line for me - totally exiting centmin.sh menu and never returns to main menu. May I ask what terminal emulation mode you are using in SecureCRT. I use Xterm




So i can't reproduce your issue. I think for now I will add a 2nd do you want to continue prompt after entering version numbers so you do not need to do ctrl+c at that stage at least and also add ctrl+z signal, SIGTSTP to centmin.sh menu's trap routine so centmin.sh menu exits on ctrl+z signal SIGTSTP detection too as it does for ctrl+c.

ok found the problem it's do with how you initially call centmin.sh menu. The problem you have is when you type command = centmin to call centmin.sh as /usr/bin/centmin is the command script which calls centmin.sh so centmin.sh menu is running as a child script of /usr/bin/centmin in a subshell so when you exit (ctrl+c) or move to background (ctrl+z) centmin.sh, you are leaving the parent /usr/bin/centmin running.

I usually run centmin.sh via

Code (Text):

cmdir
./centmin.sh

which changes to /usr/local/src/centmin directory and directly calls centmin.sh so when you exit (ctrl+c) or move to background (ctrl+z) centmin.sh, you are terminating centmin.sh properly.

so fix I made in /usr/bin/centmin will be to call centmin.sh in same shell rather than subshell so when you exit (ctrl+c) or move to background (ctrl+z) centmin.sh, centmin.sh and /usr/bin/centmin will both exit

updating 123.09beta01 for this fix

so update via cmupdate command and run centmin.sh menu once for updating /usr/bin/centmin

ah yes i got that too will look into it, thanks

though it's normal as pre-fix centmin command won't have function reference until centmin.sh updates /usr/bin/centmin

edit: believe i fixed that with another update now
