| | Display system calls for a program on Unix
You can use truss to view system calls for a specific program, for example:
truss ls
execve("/usr/bin/ls", 0xFFBFFB1C, 0xFFBFFB24) argc = 1
resolvepath("/usr/lib/ld.so.1", "/usr/lib/ld.so.1", 1023) = 16
resolvepath("/usr/bin/ls", "/usr/bin/ls", 1023) = 11
stat("/usr/bin/ls", 0xFFBFF8E0) = 0
open("/var/ld/ld.config", O_RDONLY) ... | | More...
