. Print message at script start telling how to get te summary . Print the syscall name Now it looks like this: [root@emilia ~]# perf trace syscall-counts Press control+C to stop and show the summary ^C syscall events: event count ---------------------------------------- ----------- read 102752 open 1293 close 878 write 319 stat 185 fstat 149 getdents 116 mmap 98 brk 80 rt_sigaction 66 munmap 42 mprotect 24 lseek 21 lstat 7 rt_sigprocmask 4 futex 3 statfs 3 ioctl 3 readlink 2 select 2 getegid 1 geteuid 1 getgid 1 getuid 1 getrlimit 1 fcntl 1 uname 1 [root@emilia ~]#
