Can anyone offer some advice /bin/sh avoidance with make?
I'm trying to figure out how to trigger make-3.79.1-3 to avoid
invoking /bin/sh unnecessarily.
I construct a makefile:
all: ; sleep 15
Then I try:
bash-2.05$ echo $SHELL
/bin/sh
bash-2.05$ ps
PID PPID PGID WINPID TTY UID STIME COMMAND
317 1 317 317 -1 500 14:59:36 /bin/bash
261 317 261 458 -1 500 14:59:36 /usr/bin/ps
bash-2.05$ make -f ../foo.mk
ps
PID PPID PGID WINPID TTY UID STIME COMMAND
317 1 317 317 -1 500 14:59:36 /bin/bash
461 317 461 549 -1 500 14:59:41 /usr/bin/make
591 461 461 224 -1 500 14:59:41 /bin/sh
662 591 461 585 -1 500 14:59:41 /usr/bin/ps
I then try with SHELL unset:
bash-2.05$ unset SHELL
bash-2.05$ echo $SHELL
bash-2.05$ make -f ../foo.mk
ps
PID PPID PGID WINPID TTY UID STIME COMMAND
317 1 317 317 -1 500 14:59:36 /bin/bash
465 317 465 563 -1 500 15:01:41 /usr/bin/make
666 465 465 620 -1 500 15:01:41 /bin/sh
699 666 465 710 -1 500 15:01:41 /usr/bin/ps
