( ) 指令群组 (command group) 用括号将一串连续指令括起来,这种用法对 shell 来说,称为指令群组。如下面的例子:(cd ~ ; vcgh=`pwd` ;echo $vcgh),指令群组有一个特性,shell会以产生 subshell来执行这组指令。因此,在其中所定义的变数,仅作用于指令群组本身。我们来看个例子# cat ftmp-01#!/bin/basha...
overhead. If FD is a `regular' Unix file, using lseek is enough to get its `size' in bytes. Otherwise, read blocks of BUFFER_SIZE bytes at a time until EOF. Note that the `size' (number of bytes) that wc reports is smaller than stats.st_size when the file is not positioned at...
