REG_NEWLINE 识别换行符,这样'$'就可以从行尾开始匹配,'^'就可以从行的开头开始匹配。 2、regexec函数 功能:函数regexec 会使用这个数据在目标文本串中进行模式匹配。 原型:int regexec(const regex_t *preg, const char *string, size_t nmatch,regmatch_t pmatch[], int eflags); 先来介绍下参数4中的...
When the -v or --invert-match option is also used, grep stops after outputting NUM non-matching lines. -o, --only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line. -q, --quiet, --silent Quiet; do not write ...

Multiple lines may be matched by patterns that match newline characters. Use option -o to output the match only, not the full lines(s) that match.To match a \n line break, include \n in the pattern to match the LF character. If you want to match \r\n and \n line breaks, use ...

If the first few bytes of a file indicate that the file contains binary data, assume(假定) that the file(二进制文件) is of type TYPE. By default, TYPE isbinary, and grep normally outputs either aone-line messagesaying that a binary file matches, or no message if there is no match. ...
