[FILE…] 将二进制文件当做文本文件来处理。 下图中hello_grep.out为二进制文件(可执行文件),不加-a参数,grep会提示二进制文件无法进行匹配。 28. grep --binary-files=TYPE PATTERN… [FILE…] TYPE的值可以为:binary(默认)、without-match、text,binary和without-match的区别是前者使用时会提示二进制文件无法...
grep [-E|-F] [-c|-l|-q] [ -R [-H | -L | -P] ] [-ihnsvwxy] [-e pattern_list] [-f pattern_file] [pattern] [file ...] Description The grep utility searches the given input files selecting lines which match one or more patterns. The type of patterns is controlled by the...
Be quiet; don't write anything to the standard output, regardless of matching lines. -s Suppress the error messages ordinarily written for nonexistent or unreadable files. Other error messages aren't suppressed. -v Select only those lines that don't match the specified patterns. -x Consider...
