我知道该-s选项应该显示更长的参数,但它总是不起作用(可能是因为那些大括号意味着数组或嵌套参数？).
即使在运行strace -s1000 my_command此参数后仍然被截断:
ioctl(3,SNDCTL_TMR_TEMPO或TCGETA,{B9600 -opost -isig -icanon -echo ...})= 0
我怎么能看到完整的论点？
我想通过ls命令知道linux中使用哪个系统调用来显示文件夹(或文件的名称)？特别是以"."开头的文件/文件夹.(点)
我执行了strace ls -a命令来查看系统fstat调用.对于所有其他属性(inode到permisisons),会发生很多调用.哪一个实际上给它的名字？
