Hi jeff,

[root@ondemand e93d86ab-a941-439e-8a4d-92c7434a5c48]# cat /home/xfce/ondemand/data/sys/dashboard/batch_connect/sys/bc_desktop/hpc/output/e93d86ab-a941-439e-8a4d-92c7434a5c48/script.sh
#!/usr/bin/env bash

Change working directory to user’s home directory

cd “${HOME}”

Reset module environment (may require login shell for some HPC clusters)

module purge && module restore

Ensure that the user’s configured login shell is used

export SHELL="$(getent passwd $USER | cut -d: -f7)"

Start up desktop

echo “Launching desktop ‘xfce’…”
echo “hadi baslayalim”
source “/home/xfce/ondemand/data/sys/dashboard/batch_connect/sys/bc_desktop/hpc/output/e93d86ab-a941-439e-8a4d-92c7434a5c48/desktops/xfce.sh”
echo “Desktop ‘xfce’ ended…”
[root@ondemand e93d86ab-a941-439e-8a4d-92c7434a5c48]#

this file there isn’t a line :179 :slight_smile:
