# Usage: sh shell-tracer.sh <TIME_CMD> <OUTPUT_FILE> <OLD_SHELL> <shell command line>
|
|
#
|
|
# This shell script is supposed to be set as a replacement for SHELL in make,
|
|
# causing it to be called whenever make wants to execute shell commands.
|
|
# The <shell command line> is suitable for passing on to the old shell,
|
|
# typically beginning with -c.
|
|
#
|
|
# This script will make sure the shell command line is executed with
|
|
# OLD_SHELL -x, and it will also store a simple log of the the time it takes to
|
|
# execute the command in the OUTPUT_FILE, using the "time" utility as pointed
|
|
# to by TIME_CMD. If TIME_CMD is "-", no timestamp will be stored.
