Package: x2goserver Version: 4.0.1.19 When establishing a new x2go session, I noticed that my .bashrc file is read/sourced/executed many times, in the end screwing up my PATH and LD_LIBRARY_PATH settings (amongst others). I was surprised, because .bashrc is only supposed to be read when opening an interactive shell, and I am not expecting x2go to run interactive shells here. I did some debugging by placing the following at the start of my .bashrc: echo "bashrc" >> ~/slog ps -fea | grep boekhold >> ~/slog and based on this I can see x2go constantly running commands like: bash -c bash -c 'echo "X2GODATABEGIN:60b25f89-31db-46ec-8a7c-c93002fbfa50"; export PATH="/usr/local/bin:/usr/bin:/bin"; export HOSTNAME && x2golist still at first glance no reason for bash to process .bashrc. However, further testing: boekhold@xbmc:~$ rm slog rm: cannot remove ‘slog’: No such file or directory boekhold@xbmc:~$ bash -c date Sun Nov 22 19:39:09 GST 2015 boekhold@xbmc:~$ cat slog cat: slog: No such file or directory boekhold@xbmc:~$ bash -c bash -c date boekhold@xbmc:~$ cat slog bashrc boekhold 1147 1 1 Nov21 ? 00:20:20 ..... ..... See there? Running "bash -c bash -c" suddenly tricks bash into reading the .bashrc file. No idea how, but it happens. This is on Linux Mint 17.2, but I'm experiencing the same issue on a Centos 7 system with the x2go EPEL packages. Client is x2goclient on Windows 7 Professional SP1. I can't figure out where that "bash -c bash -c" command is being generated, hope that somebody from the X2Go team can provide some guidance here? Maarten
