I have ATT's Sys V/386 R3.0 V1.0 on an intel 80386 PC/AT bus type machine. We aquired a copy of csh through intel's Berkeley source license. OTHERSH was set to /bin/sh before compiling it. Shell scripts written with '#' as the first character are run by /bin/sh EXCEPT when executed from a makefile. make reads the script and feeds it to the shell defined by $SHELL. Is there a convention for shell and environment variables to define the interactive shell and the batch shell differently? Currently I `set shell=/bin/csh` and `setenv SHELL /bin/sh` However in an attempt to emulate BSD job control I was investigating `shl` the SYS V shell layer facility and found it creates virtual terminals running the shell defined in $SHELL. This does note sweetly and cleanly allow me to provide our customers with a csh environment with "job control" in a System V system. Suggestions?

All shell scripts are run by the /bin/sh, except make which runs the scripts by the $SHELL - unless you define the variable SHELL inside the makefile - do a SHELL= /bin/sh and all scripts are run by the SHELL variable defined in the makefile.
