grep -vwf 1.list 2.list //在2.list中删除与1.list相同的行并输出 grep -vFf 1.list 2.list //在2.list中删除与1.list相同的行并输出 1. 2. 3. 4. -f<规则文件> 或 --file=<规则文件>: 指定规则文件,其内容含有一个或多个规则样式,让grep查找符合规则条件的文件内容,格式为每行一个规则样式。
POSIX requires that options that follow file names must be treated as file names; by default, such options are permuted to the front of the operand list and are treated as options. Also, POSIX requires that unrecognized options be diagnosed as “illegal”, but since they are not really ...
grep "match_pattern" dir -r --exclude "filename" 如果需要排除的文件很多,可以将要排除的文件名写入一个文件FILE中,其中每一个文件名占一行 grep "match_pattern" dir -r --exclude-from FILE 在dir目录下搜索除了subdir目录下的文件 grep "match_pattern" dir -r --exclude-dir subdir 注意: subdir 不...
-m NUM, --max-count=NUM Stop reading a file after NUM matching lines. If the input is standard input from a regular file, and NUM matching lines are output, grep ensures that the standard input is positioned to just after the last matching line before exiting,regardless of the presence(...
caution: filename not matched: visit.zip 因为会认为后面三个zip文件是在第一个zip文件里面的,因此需要 unzip '*.zip' 或者 unzip "*.zip" 或者 unzip \*.zip 来屏蔽掉linux的通配符(man可以看到Be sure to quote any character that might otherwise be interpreted or modified by the operating system, ...
grep 从输入的文件中,寻找与 pattern list 匹配的行。 因为换行符也是 pattern list 的分隔符,所以不可能对换行符做匹配。 1.2 调用 grep 的语法 grep OPTIONS.. PATTERN INPUT_FILE_NAMES.. 除了这种写法,pattern 也可以由 -e PATTERN 给出,或者从文件中读取 pattern -f FILE 。

Grep搜索以FILE命名的文件输入 (或者是标准输入,如果没有指定文件名,或者给出的文件名是-的话),寻找含有与给定的模式PATTERN相匹配的内容的行。默认情况下,grep将把含有匹配内容的行打印出来。 另外,也可以使用两个变种程序egrep和fgrep。Egrep与grep -E相同。Fgrep与grep -F相同。
