Try this and then re-run Considering you're using Linux: export PATH=$PATH:<installed_quartus_directory>/<version>/quartus/bin On Window 1) Open up your command prompt (cmd) 2) Type set PATH=%PATH%;C:\altera\12.1\quartus\bin Change the back party of the PATH after ';' according to your quartus installation directory Then try to run quartus_sh again Similar issue found out that might be helping. https://community.intel.com/t5/Intel-Quartus-Prime-Software/cannot-execute-quartus-sh-in-command-line/td-p/153115
