我的计算机应用需要读到文字档案中。 我有几次工作,有一次没有工作;该方案没有读到,告诉我,有些地方有坏。 我的第一gues是,有些地方具有非敌对性,但我不知道如何找到。 Per或任何普通reg都是冰。 任何想法?
您可使用<代码>[^x20-x7E],与非ASCII特性相匹配。
e.g. grep -P [^x20-x7E] suspicious_file
perl -wne printf "byte %02X in line $.
", ord $& while s/[^
x20-x7E]//;
将发现并非ASCII营养特性、表、空间或新线的特性。
If it reports 0Ds (carriage-returns) in files that are O.K., then change
to
.
如果在坏的档案中只报告0D,那么你可能通过操作dos2unix将这些文件固定下来。
如果你在源代码中使用推器,则尝试这种模式:
[^x08-x7E]
