25 # Usage: sh shell-tracer.sh <TIME_CMD> <OUTPUT_FILE> <OLD_SHELL> <shell command line> |
|
26 # |
|
27 # This shell script is supposed to be set as a replacement for SHELL in make, |
|
28 # causing it to be called whenever make wants to execute shell commands. |
|
29 # The <shell command line> is suitable for passing on to the old shell, |
|
30 # typically beginning with -c. |
|
31 # |
|
32 # This script will make sure the shell command line is executed with |
|
33 # OLD_SHELL -x, and it will also store a simple log of the the time it takes to |
|
34 # execute the command in the OUTPUT_FILE, using the "time" utility as pointed |
|
35 # to by TIME_CMD. If TIME_CMD is "-", no timestamp will be stored. |
