Book Abstract

2.5.2 less命令
当要查看的文件过大或者内容多得需要滚动屏幕的时候,可以使用less命令。如要查看像/usr/share/dict/words这样的大文件,可以使用less /usr/share/dict/words命令。less命令可以将内容分屏显示,按空格键可查看下一屏,B键查看上一屏,Q键退出。
你可以在less命令的输出结果中进行搜索。例如:使用/word从当前位置向前搜索word这个词,使用?word从当前位置向后搜索。当找到一个匹配的时候,按N键可以跳到下一个匹配。
你可以将几乎所有进程的输出作为另一个进程的输入,我们将在2.14节详细介绍。当你执行的命令涉及很多输出,或者你想使用less来查看输出结果的时候,这个方法非常管用,比如下例所示:
你可以自己亲身实践一下这个命令。类似这样的less代码你会常用到。
2.5.3 pwd命令
pwd命令仅输出当前的工作目录名。这个命令看上去不是那么有用,其实不然,它有以下两个用处。
首先,并不是所有的提示符都显示当前目录名,甚至有时候你需要摆脱它,因为它占用很大空间,这时候就需要使用pwd来解决。
其次,使用符号链接(我们将在2.17.2节介绍)的时候通常很难获知当前目录信息,这时我们可以使用pwd—P来查看。
