But I’d still like to understand why this does not work in a script. Of course this is remedied by assigning our fortune result to a variable, then using xsetroot with said variable. Yet that same fails when run from a shell script: #!/bin/shĬat /tmp/afile | while read do echo "$REPLY" done To this end, printing a fortune works fine in a terminal: fortune -s | while read -r do xsetroot -name "$REPLY" done I ran into this interesting issue while populating my WM bar with info text, which is applied by setting the root window’s title, i.e.
