I have a bash script to generate the sig featured below. #!/bin/bash # script to generate a topical linux mailsig SIGFILE=/home/bob/Documents/Signatures/daily.sig : > $SIGFILE # (re)creates an empty SIGFILE echo "Bob Williams" >> $SIGFILE echo " System: " `uname -sr` >> $SIGFILE distro=" $(head -n 1 /etc/SuSE-release)" kde=`kf5-config -v | grep KDE` Qt=`kf5-config -v | grep Qt` plasma=`kcmshell5 -v | awk '{print $2}'` echo " Distro: $distro" >> $SIGFILE echo " Desktop: $kde, $Qt and Plasma: $plasma" >> $SIGFILE exit 0 When run from my user command line it works correctly, but when I run it from my crontab, it fails to get the plasma version. So the last line of output reads: Desktop: KDE Frameworks: 5.26.0, Qt: 5.6.1 and Plasma: The error message returned by the system is: QXcbConnection: Could not connect to display I'm guessing that cron is not running in graphical environment, but not sure why that would make a difference. Can anyone suggest a solution/workaround, please? -- Bob Williams System: Linux 4.4.22-1-default Distro: openSUSE 42.2 Beta (x86_64) Desktop: KDE Frameworks: 5.26.0, Qt: 5.6.1 and Plasma: 5.8.0
