Matching Control -e PATTERN, --regexp=PATTERN Use PATTERN as the pattern. This can be used to specify multiple search patterns, or to protect a pattern beginning with a hyphen (-). (-e is specified by POSIX.) -f FILE, --file=FILE Obtain patterns from FILE, one per line. The empty...
Use PATTERN as the pattern. This can be used to specify multiple search patterns, or to protect a pattern beginning with a hyphen (-). 即,在 -e 选项后面的 PATTERN 参数会被当成要匹配的模式字符串,提供多个 -e 选项就能匹配多个模式字符串。

Utilizing an alternate syntax of the grep query in the shell can exclude matching patterns or related lines when using multiple patterns. In previous examples, we used the "text" and "is" patterns in the command to exclude lines from the "new.txt" file. As a result, the output of this...
