Frequently Asked Questions

==========================

|
|
|
Q: How can I copy & paste without decorations?
|
|
----------------------------------------------
|
|
|
|
:Answer: There are a couple ways to do this:
|
|
|
|
* Use the :ref:`bookmark<hotkeys_bookmarks>` hotkeys to mark lines and then
|
|
press :kbd:`c` to copy to the local system keyboard. The system clipboard
|
|
is accessed using commands like :code:`pbcopy` and :code:`xclip`. See the
|
|
:ref:`tuning` section for more details.
|
|
|
|
If a system clipboard is not available,
|
|
the `OSC 52 <https://www.reddit.com/r/vim/comments/k1ydpn/a_guide_on_how_to_copy_text_from_anywhere/>`_
|
|
terminal escape sequence will be tried. If your terminal supports this
|
|
escape sequence, the selected text will be copied to the clipboard, even
|
|
if you are on an SSH connection.
|
|
|
|
* Press :kbd:`CTRL` + :kbd:`l` to temporarily switch to "lo-fi"
|
|
mode where the contents of the current view are printed to the terminal.
|
|
This option is useful when you are logged into a remote host.

Q: How can I force a format for a file?
|
|
---------------------------------------
|
|
|
|
:Answer: The log format for a file is automatically detected and cannot be
|
|
forced.
|
|
|
|
:Solution: Add some of the log file lines to the :ref:`sample<format_sample>`
|
|
array and then startup lnav to get a detailed explanation of where the format
|
|
patterns are not matching the sample lines.
|
|
|
|
:Details: The first lines of the file are matched against the
|
|
:ref:`regular expressions defined in the format definitions<format_regex>`.
|
|
The order of the formats is automatically determined so that more specific
|
|
formats are tried before more generic ones. Therefore, if the expected
|
|
format is not being chosen for a file, then it means the regular expressions
|
|
defined by that format are not matching the first few lines of the file.
|
|
|
|
See :ref:`format_order` for more information.
|
|
|
|
|
|
Q: How can I search backwards, like pressing :kbd:`?` in less?
|
|
--------------------------------------------------------------
|
|
|
|
:Answer: Searches in **lnav** runs in the background and do not block input
|
|
waiting to find the first hit. While the search prompt is open, pressing
|
|
:kbd:`CTRL` + :kbd:`j` will jump to the previous hit that was found. A
|
|
preview panel is also opened that shows the hits that have been found so
|
|
far.
|
|
|
|
After pressing :kbd:`Enter` at the search prompt, the view will jump to
|
|
the first hit that was found. Then, you can press :kbd:`n` to move to
|
|
the next search hit and :kbd:`N` to move to the previous one. If you
|
|
would like to add a hotkey for jumping to the previous hit by default,
|
|
enter the following configuration command:
|
|
|
|
.. code-block:: lnav
|
|
|
|
:config /ui/keymap-defs/default/x3f/command :prompt --alt search ?
|
|
|
|
|
|
Q: Why isn't my log file highlighted correctly?
|
|
-----------------------------------------------
|
|
|
|
TBD
|
|
|
|
Q: Why isn't a file being displayed?
|
|
------------------------------------
|
|
|
|
:Answer: Plaintext files are displayed separately from log files in the TEXT
|
|
view.
|
|
|
|
:Solution: Press the :kbd:`t` key to switch to the text view. Or, open the
|
|
files configuration panel by pressing :kbd:`TAB` to cycle through the
|
|
panels, and then press :kbd:`/` to search for the file you're interested in.
|
|
If the file is a log, a new :ref:`log format<log_formats>` will need to be
|
|
created or an existing one modified.
|
|
|
|
:Details: If a file being monitored by lnav does not match a known log file
|
|
format, it is treated as plaintext and will be displayed in the TEXT view.
