3.使用参数-o 保存strace结果 The following examples stores the strace output to output.txt file. 下面的列子展示strace命令输出的output.txt文件 View Code 4.使用-p 参数来strace一个运行中进程 You could execute strace on a program that is already running using the process id. First, identify the ...
as in this example : open(AT_FDCWD, “/etc/ld.so.cache”, O_RDONLY|O_CLOEXEC) =3 fstat(3, {st_mode=S_IFREG|0644, st_size=140857, …})=0 Strace Error Codes Strace displays c language error codes, Errors (typically a return value of -1) have the errno symbol and error string ...
3. Save the Trace Execution to a File Using Option -o The following examples stores the strace output to output.txt file. $ strace -o output.txt ls Desktop Documents Downloads examples.desktop libflashplayer.so Music output.txt Pictures Public Templates Ubuntu_OS Videos $ cat output.txt exec...

参考http://www.thegeekstuff.com/2011/11/strace-examples/ 简介 strace常用来跟踪进程执行时的系统调用和所接收的信号。 在Linux世界,进程不能直接访问硬件设备,当进程需要访问硬件设备(比如读取磁盘文件,接收网络数据等等)时,必须由用户态模式切换至内核态模式,通 过系统调用访问硬件设备。strace可以跟踪到一个进程...

straceis a utility that can trace system calls. System calls are the fundamental interfaces between an applications and the kernel. They are generally not invoked directly, but rather via wrapper functions in glibc (or perhaps some other library). For examples:fstat, mmap, open, close ...
简单说,strace是可以跟踪一个程序在做什么的命令。 一 它可以监控某个要执行的命令,比如平时最常见的ls命令: [root@localhost a]# strace ls execve(“/bin/ls”, [“ls”], [/* 26 vars */]) = 0 brk(0) = 0x11a8000 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1...
