more (more) 该命令一次显示一屏文本,满屏后停下来,并且在屏幕的底部出现一个提示信息,给出至今己显示的该文件的百分比,方便逐页阅读(file perusal filter for crt viewing) 。more名单中内置了若干快捷键,按空白键(space)就往下一页显示,按 b 键就会往回(back)一页显示,而且还有搜寻字串的功能(与 vi 相似),使用中按h可以查看说明文件 。
more [-dlfpcsu] [-num] [+/pattern] [+linenum] [fileNames..]
-num 一次显示的行数 -d 提示使用者,在画面下方显示 [Press space to continue, ‘q‘ to quit.] ,如果使用者按错键,则会显示 [Press ‘h‘ for instructions.] 而不是 ‘哔‘ 声 -l 取消遇见特殊字元 ^L(送纸字元)时会暂停的功能 忽略Ctrl+l(换页)字符 -f 计算行数时,以实际上的行数,而非自动换行过后的行数(有些单行字数太长的会被扩展为两行或两行以上) -p 不以卷动的方式显示每一页,而是先清除萤幕后再显示内容 -c 跟 -p 相似,不同的是先显示内容再清除其他旧资料 -s squeese 当遇到有连续两行以上的空白行,就代换为一行的空白行 -u 不显示下引号 (根据环境变数 TERM 指定的 terminal 而有所不同) +/ 在每个档案显示前搜寻该字串(pattern),然后从该字串之后开始显示 +num 从第 num 行开始显示 fileNames 欲显示内容的档案,可为复数个数
