My grep-a-like program ack has a -1 option that stops at the first match found anywhere. It supports the -m 1 that @mvp refers to as well. I put it in there because if I'm searching a big tree of source code to find something that I know exists in only one file, it's unnec...
默认会搜索所有文件,将二进制文件也当做text进行搜索。 如果指定-I或--binary-files=without-match选项,则二进制文件即使包含相应字符串,也当做不包含该内容处理。 $ grep -rnwlI sec_read_otp_bit . ./security/verify_ssbl.c ./security/boot_defines.h ... ./objs/7260b0/security/bsp_utils.i ./objs/...
首先,确保你已经安装了grep工具。grep是一个强大的文本搜索工具,可以在文件中查找指定的字符串。 在循环开始之前,定义一个包含要搜索的字符串的变量。例如,假设要搜索的字符串是"example",可以使用以下命令定义变量: 在循环开始之前,定义一个包含要搜索的字符串的变量。例如,假设要搜索的字符串是"example",可以使用...
If there is more than one match in a line, each of them is shown separately. If -o is combined with -v (invert the sense of the match to find non-matching lines), no output is generated, but the return code is set appropri- ately. If the matched portion of the line is SunOS ...

regexpr返回与text相同长度的整数向量,给出第一个匹配的起始位置或(如果没有),属性"match.length"是给出匹配文本长度的整数向量(或表示不匹配)。匹配位置和长度以字符为单位,除非使用useBytes = TRUE,否则它们以字节为单位(因为它们仅用于 ASCII 匹配:在任何一种情况下,都会在结果上设置值为TRUE的属性useBytes)。如...

When using the -v or --invert-match option, the search stops after the specified number of non-matches. A value of -1 will return unlimited results (the default). A value of 0 will exit immediately with a non-zero status. --threads <num> Number of grep worker threads to use. See...
