mac lessコマンド実行時に行番号を表示する
macで、コマンドを実行して、lessコマンド実行時に行番号を表示する手順を記述してます。
環境
- ProductName: macOS
- ProductVersion: 11.5.2
- BuildVersion: 20G95
行番号を表示
「less」コマンド実行時に行番号を表示するには、オプション「-N」を使用します。
例えば「httpd.conf」を「less」コマンドで行番号を表示して、確認する場合は以下となります。
less -N httpd.conf
実行結果
ちなみに「cat」の場合は「-n」となります。
cat -n httpd.conf
<出力結果>

2 # This is the main Apache HTTP server configuration file. It contains the
3 # configuration directives that give the server its instructions.
4 # See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.
5 # In particular, see
6 # <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>
7 # for a discussion of each configuration directive.
8 #
9 # Do NOT simply read the instructions in here without understanding
10 # what they do. They're here only as hints or reminders. If you are unsure
11 # consult the online docs. You have been warned.
12 #
13 # Configuration and logfile names: If the filenames you specify for many
14 # of the server's control files begin with "/" (or "drive:/" for Win32), the
15 # server will use that explicit path. If the filenames do *not* begin
16 # with "/", the value of ServerRoot is prepended -- so "logs/access_log"
17 # with ServerRoot set to "/usr/local/apache2" will be interpreted by the
18 # server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
19 # will be interpreted as '/logs/access_log'.
20
21 #
22 # ServerRoot: The top of the directory tree under which the server's
23 # configuration, error, and log files are kept.
24 #
25 # Do not add a slash at the end of the directory path. If you point
26 # ServerRoot at a non-local disk, be sure to specify a local disk on the
27 # Mutex directive, if file-based mutexes are used. If you wish to share the
28 # same ServerRoot for multiple httpd daemons, you will need to change at
29 # least PidFile.
30 #
31 ServerRoot "/usr"
32
33 #
34 # Mutex: Allows you to set the mutex mechanism and mutex file directory
35 # for individual mutexes, or change the global defaults
36 #
37 # Uncomment and change the directory if mutexes are file-based and the default
38 # mutex file directory is not on a local disk or is not appropriate for some
39 # other reason.
40 #
41 # Mutex default:/private/var/run
42
43 #
44 # Listen: Allows you to bind Apache to specific IP addresses and/or
45 # ports, instead of the default. See also the <VirtualHost>
46 # directive.
47 #
48 # Change this to Listen on specific IP addresses as shown below to
49 # prevent Apache from glomming onto all bound IP addresses.
50 #
51 #Listen 12.34.56.78:80
52 <IfDefine SERVER_APP_HAS_DEFAULT_PORTS>
53 Listen 8080
54 </IfDefine>
55 <IfDefine !SERVER_APP_HAS_DEFAULT_PORTS>
56 Listen 80
57 </IfDefine>

60 # Dynamic Shared Object (DSO) Support
61 #
62 # To be able to use the functionality of a module which was built as a DSO you
63 # have to place corresponding `LoadModule' lines at this location so the
64 # directives contained in it are actually available _before_ they are used.
65 # Statically compiled modules (those listed by `httpd -l') do not need
66 # to be loaded here.
67 #
68 # Example:
69 # LoadModule foo_module modules/mod_foo.so
70 # LoadModule my_custom_module /usr/local/libexec/mod_my_custom.so "My Signature Authority"
71 #
72 #LoadModule mpm_event_module libexec/apache2/mod_mpm_event.so
73 LoadModule mpm_prefork_module libexec/apache2/mod_mpm_prefork.so
74 #LoadModule mpm_worker_module libexec/apache2/mod_mpm_worker.so
75 LoadModule authn_file_module libexec/apache2/mod_authn_file.so
76 #LoadModule authn_dbm_module libexec/apache2/mod_authn_dbm.so
77 #LoadModule authn_anon_module libexec/apache2/mod_authn_anon.so
