---------------------------------------------------
A search pattern may be preceded by one or more of:
^N or ! Search for NON-matching lines.
Atau di man less
:
/pattern
Search forward in the file for the N-th line containing the pat‐
tern. N defaults to 1. The pattern is a regular expression, as
recognized by the regular expression library supplied by your
system. The search starts at the first line displayed (but see
the -a and -j options, which change this).
Certain characters are special if entered at the beginning of
the pattern; they modify the type of search rather than become
part of the pattern:
^N or !
Search for lines which do NOT match the pattern.
Jadi, pola adil !
adalah pola kosong (yang cocok dengan apa pun) dinegasikan - jadi tidak ada yang cocok dengan itu.
Anda harus melarikan diri dari pentingnya !
pada awal pola, dengan menggunakan backslash ( \!
), atau membuatnya bukan karakter pertama dari regex ( /[!]
, misalnya).
Cara lain adalah menggunakan grep
:
$ man find | grep !
with `-', or the argument `(' or `!'. That argument and any following
! expr True if expr is false. This character will also usually need
Same as ! expr, but not POSIX compliant.
The POSIX standard specifies parentheses `(', `)', negation `!' and the
find /sbin /usr/sbin -executable \! -readable -print
find . -perm -444 -perm /222 ! -perm /111
find . -perm -a+r -perm /a+w ! -perm /a+x
-perm /222 or -perm /a+w) but are not executable for anybody ( ! -perm
/111 and ! -perm /a+x respectively).
