Linux Commandltrace 用来跟踪进程调用库函数的情况 补充说明 ltrace命令 是用来跟踪进程调用库函数的情况。 语法 ltrace [option ...] [command [arg ...]] 选项 -a 对齐具体某个列的返回值。 -c 计算时间和调用,并在程序退出时打印摘要。 -C 解码低级别名称(内核级)为用户级名称。 -d 打印调试信息。
19。 -u USERNAME run command with the userid, groupid of username.使用某个用户ID或组ID来运行命令 20。 -V, --version output version information and exit.打印版本信息,然后退出 21。 -x NAME treat the global NAME like a library subroutine.--- 不好意思,这句话还真不知怎么翻译好 ---###...
命令的使用方式: <trace|strace|ltrace> <COMMAND> <trace|strace|ltrace> -p <PID> 常用选项: -f, -F同时跟踪fork和vfork出来的进程 -o file结果输出到某个文件 -e execve只记录 execve 这类系统调用 -p PID追踪指定 PID 对应的进程 -D输出前加时间戳 案例 Error message: $ clint foo.cpp Segmentation...

In RHEL7, the ltrace command options have been changed from RHEL6. For example, "-A MAXELTS" is added, and "-d" is deleted. Functional change in -e/-l/-x option Addition of -C/--demangle option Deletion of -g/--no-plt optionEnvironment...

Ltrace is a debugging program which runs a specified command until the command exits. While the command is executing, ltrace intercepts and records both the dynamic library calls called by the executed process and the signals received by the executed process. Ltrace can also intercept and print ...

Command-line utility命令行应用 ---> Invokes functions from system libraries (glibc)系统lib库 ---> Invokes system calls。 ls命令调用Linux上系统lib库的函数。这些lib又触发系统调用完成整个任务。 ltrace:know the functions were called from the glibc library ...
The ltrace command can be used to intercept and record the dynamic calls made to shared libraries. The amount of output generated by the ltrace command can be overwhelming for some commands (especially if the -S option is used to also show system calls).
