The command ltrace enables you to trace the
library calls of a process. This command is used in a similar
fashion to strace. The parameter
-c
outputs the number and duration of the library
calls that have occurred:
$ ltrace -c find /usr/share/doc % time seconds usecs/call calls errors syscall ------ ----------- ----------- --------- --------- ---------------- 86.27 1.071814 30 35327 write 10.15 0.126092 38 3297 getdents64 2.33 0.028931 3 10208 lstat64 0.55 0.006861 2 3122 1 chdir 0.39 0.004890 3 1567 2 open [...] 0.00 0.000003 3 1 uname 0.00 0.000001 1 1 time ------ ----------- ----------- --------- --------- ---------------- 100.00 1.242403 58269 3 total
