Pages are assumed to be delimited by form feeds 假定页由换页符定界。
If input is form - feed - delimited , it counts form feeds instead 如果输入是换页定界的,则selpg改为统计换页符。
Matches a form feed - u000c 与换页符 u000c匹配。
Matches a form - feed character 换页符匹配。
Matches any white space character including space , tab , form - feed , and so on 匹配任何空白字符,包括空格、制表符、换页符等。
Check each char read to see whether it is a form feed ; if so , increment the page counter 检查每个读取的字符是否为换页符;若是,则增加页计数器。
This tells selpg to look for form feed characters in the input and treat them as the page delimiters 该命令告诉selpg在输入中寻找换页符,并将其作为页定界符处理。
Printers recognize the form - feed character and automatically advance the print head by the required number of lines necessary to begin the next line of data on a new page 打印机会识别换页符并自动根据在新的页开始新行所需的行数移动打印头。
