The following are examples of sh_calls.d.
This is a simple script to count Bourne shell calls. Here it traces an
example program, Code/Perl/func_abc.sh.
# sh_calls.d
Tracing... Hit Ctrl-C to end.
^C
FILE TYPE NAME COUNT
func_abc.sh func func_a 1
func_abc.sh func func_b 1
func_abc.sh func func_c 1
func_abc.sh builtin echo 3
func_abc.sh cmd sleep 3
While tracing, function func_a() from the program "func_abc.sh" was executed
once, along with func_b() and func_c(). The "echo" builtin was called 3
times, as was the "sleep" command.
The following traced the firefox start script,
# sh_calls.d
Tracing... Hit Ctrl-C to end.
^C
FILE TYPE NAME COUNT
firefox builtin . 1
firefox builtin break 1
firefox builtin exit 1
firefox builtin pwd 1
firefox builtin test 1
firefox cmd /usr/lib/firefox/run-mozilla.sh 1
run-mozilla.sh builtin break 1
run-mozilla.sh builtin exit 1
run-mozilla.sh builtin return 1
run-mozilla.sh builtin shift 1
run-mozilla.sh builtin type 1
run-mozilla.sh cmd /usr/lib/firefox/firefox-bin 1
run-mozilla.sh func moz_run_program 1
run-mozilla.sh func moz_test_binary 1
firefox builtin echo 2
firefox func moz_pis_startstop_scripts 2
firefox builtin cd 3
firefox builtin export 3
run-mozilla.sh builtin export 3
firefox builtin : 6
firefox func moz_spc_verbose_echo 6
run-mozilla.sh subsh - 9
firefox builtin [ 18
firefox subsh - 20
run-mozilla.sh builtin [ 20
The firefox start script called run-mozilla.sh, which can be seen both
as a "cmd" call in the above output from the "firefox" script, and as
additionall calls from the "run-mozilla.sh" script.
The builtin called "[" is the test builtin, and was called 20 times by
"run-mozilla.sh" and 18 times by "firefox". The "firefox" script also called
20 subshells.
