若TYPE为without-match,遇到此参数, grep会认为此二进位档案没有包含任何搜寻样式,与-I 参数相同。 若TPYE为text, grep会将此二进位档视为text档案,与-a 参数相同。 Warning: --binary-files=text 若输出为终端机,可能会产生一些不必要的输出。 7. -c, --count 不显示符合样式行,只显示符合的总行数。 若再...

使用grep -v 可以实现 NOT 操作。-v 选项用来实现反选匹配的( invert match)。如,可匹配得到除下指定pattern外的所有lines。 grep -v 'par1' filename 2、将NOT操作与其他操作联合起来,以此实现更强大的功能组合 示例(将得到:'a1或者a2,但是不是a3'的结果): egrep 'a1|a2' filename | grep -v a3 四...
When grep stops after NUM matching lines, it outputs any trailing context lines. When the -c or --count option is also used, grep does not output a count greater than NUM. When the -v or --invert-match option is also used, grep stops after outputting NUM non-matching lines. -o,...
