在尝试 grep 查找其中包含点的字符串时，我无法获得精确匹配的字符串作为输出。
eg: grep "APPLICATION.REFERENCE.LOCAL" <FILENAME>
我什至尝试过：
grep -F 'APPLICATION.REFERENCE.LOCAL' <FILENAME>它还显示具有类似匹配的行，例如APPLICATION.REFERENCE.LOCAL1.
请帮我。
既然你正在使用-F这会将模式解释为固定弦，你需要提供-x选项完全匹配整行。
grep -Fx 'APPLICATION.REFERENCE.LOCAL' filename
From man grep:
-F, --fixed-strings
Interpret PATTERN as a list of fixed strings, separated by
newlines, any of which is to be matched. (-F is specified by
POSIX.)
-x, --line-regexp
Select only those matches that exactly match the whole line.
(-x is specified by POSIX.)
Example:
$ cat file
APPLICATION.REFERENCE.LOCAL
1APPLICATION.REFERENCE.LOCAL
APPLICATION.REFERENCE.LOCAL1
APPLICATION.REFERENCE0LOCAL
$ grep -Fx 'APPLICATION.REFERENCE.LOCAL' file
APPLICATION.REFERENCE.LOCAL
