但我想进一步排除包含merging*mb*from|merged*mb*from等模式的行。我不想要像 -

这样的行

Merging 12 MB from or Merged 12 MB from .

我尝试使用grep的-v选项，但似乎不理解区分大小写和'AND'，'OR'操作。

Answer 1

尝试grep -E（扩展正则表达式）-i（忽略大小写）-v（反转匹配）：

grep -E -i -v 'merg(ing|ed).*mb.*from'

如果您认为＆＃34;忽视案例＆＃34;很慢，那么：

grep -E -v '[Mm]erg(ing|ed).*[Mm][Bb].*[Ff]rom'

Answer 2

关注sed可能对您有帮助。

sed -n '/Merging.*MB.*from/d;/Merged.*MB.*from/d;p'   Input_file

OR

sed -n '/[mM]erging.*[mM][bB].*from/d;/Merged.*MB.*from/d;p'  Input_file

编辑： 此处为上述代码添加说明。

sed -n '                 ##-n will STOP printing by default for any line of Input_file till we print it explicitly.
/Merging.*MB.*from/d;    ##Looking for string Merging.*MB.*from and using d will skip it and will NOT print it.
/Merged.*MB.*from/d;     ##Looking for string Merged.*MB.*from and using d will skip it and will not print it.
p                        ##mentioning p will print the lines apart from lines which have above mentioned string in them
' Input_file             ##Mentioning Input_file name here.

如何不包括某些不。输出中的模式？
