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产生的系统调用,包括参数,返回值,执行消耗的时间。 strace 命令是一种...

使用linux的strace命令来跟踪psql的元命令对应的sql语句 首先说明,psql的元命令都是对应sql语句的,用不着用strace的方式来获取元命令的取数sql(因为这种方式比较麻烦), 可以用如下命令获得取数sql: psql -E 参数,可以把psql中各种以\开头的命令执行的实际SQL打印出来。
