Suppress normal output; instead print the name of each input file from which no output would normally have been printed. The scanning will stop on the first match. 抑制正常输出;而是打印通常不会输出的每个输入文件的名称。扫描将在第一场比赛中停止。 -l, --files-with-matches Suppress normal outpu...
-l(小写L), --files-with-matches Suppress normal output; instead print the name of each input filefrom whichoutput would normally have been printed. The scanningwill stop on the first match. 列出文件内容符合指定的样式的文件名称。(是只找一个包含匹配的文件,还是找这些所有文件的时候,一旦发现有匹...
The scanning will stop on the first match. 例如,我们可能想要查看某个变量出现在哪些文件中,如果打印匹配的行内容,可能会有很多输出,不方便查看文件名,就可以加上 -l 选项来指定只打印文件名。 举例如下: $ grep Fexecute -l -r ./ ./src/kwsearch.c ./src/grep.c ./src/search.h 基于这个打印...
