Basically #! scripts fail if the path to the jconsole executable contains a hyphen. Given that the default path to jconsole for a J installation is ./j64-701/bin/jconsole this means that #! scripts won't work without some extra work. The reported cause of the failure is a domain error in script_z_ and seems to be caused by J attempting to interpret the path to jconsole as a J statement and the hyphen as the J verb Minus (-). I get the same error if I change the path to ./j64+701/bin/jconsole . And no error if I change the path to ./j64_701/bin/jconsole The quick fix/workaround is to replace the hyphen in the ~install directory name to an underscore, but it would be good if this could be fixed "properly". ris...@ric-linux:~/temp$ cat testhb #!/home/rishe0/j64-701/bin/jconsole echo 'Hello world!' NB. exit 0 ris...@ric-linux:~/temp$ ./testhb |domain error: script | #!/home/rishe0/j64- 701/bin/jconsole |[-0] /home/rishe0/temp/./testhb exit 0 NB. now rename ~install folder and edit testhb ris...@ric-linux:~/temp$ cat testhb #!/home/rishe0/j64_701/bin/jconsole echo 'Hello world!' exit 0 ris...@ric-linux:~/temp$ ./testhb Hello world! ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
