However, the regular expression may become lengthy and unreadable as the number of patterns grows. To mitigate this, we can specify the patterns individually. 2.2. Specify Multiple Patterns The-eflag allows us to specify multiple patterns through repeated use.We can exclude various patterns using th...
This option is most useful when multiple-eoptions are used to specify multiple patterns, or when a pattern begins with a dash (`-'). --exclude If specified, it excludes files matching the given filename pat- tern from the search.Note that--excludepatterns take priority over--includepatterns...
Example: grep-i'hello world'menu.h main.c PATTERNS can contain multiple patterns separated by newlines. Pattern selection and interpretation:-E, --extended-regexp PATTERNS are extended regular expressions-F, --fixed-strings PATTERNS are strings-G, --basic-regexp PATTERNS are basic regular express...
Usage: grep[OPTION]... PATTERNS[FILE]... SearchforPATTERNS in each FILE. Example: grep -i'hello world'menu.h main.c PATTERNS can contain multiple patterns separated by newlines. Pattern selection and interpretation: -E, --extended-regexp PATTERNS are extended regular expressions ...
Usage: grep [OPTION]... PATTERNS [FILE]... Search for PATTERNS in each FILE. Example: grep -i 'hello world' menu.h main.c PATTERNS can contain multiple patterns separated by newlines. Pattern selection and interpretation: -E, --extended-regexp PATTERNS are extended regular expressions ...
This can be used to specify multiple search patterns, or to protect a pattern beginning with a hyphen (-). (-e is specified by POSIX.) -f FILE, --file=FILE Obtain patterns from FILE, one per line. The empty file contains zero patterns, and therefore matches nothing. (-f is ...
Grep multiple and find multiple patterns 基础概念 grep 是一个强大的文本搜索工具,它允许用户使用正则表达式来搜索文本,并打印出匹配的行。当需要在一个文件或多个文件中查找多个模式时,可以使用 grep 的一些高级选项来实现。 相关优势 灵活性:grep 支持正则表达式,可以构建复杂的搜索模式。 效率:grep 能够快速地在...
Use PATTERN as the pattern. This can be used to specify multiple search patterns, or to protect a pattern beginning with a hyphen (-). 即,在-e选项后面的PATTERN参数会被当成要匹配的模式字符串,提供多个-e选项就能匹配多个模式字符串。 注意不要在单个-e选项后面直接跟多个模式字符串,否则会报错。
If this option is used multiple times or is combined with the -f (--file) option, search for all patterns given. This option can be used to protect a pattern beginning with “-”. -f FILE, --file=FILE Obtain patterns from FILE, one per line. If this option is used multiple ...
