You can also map some other commands with 'cmap' to accept the search and execute the command immediately afterwards. This means that if the file is selected in the future, the previewer is called once again. To use this feature, you need to use a client which supports communicating with a Unix domain socket. This works by periodically calling the 'load' command. Note that some programs may not respond well to SIGPIPE to exit with a non-zero return code and avoid caching.

Now instead of using lf you can use lfcd and when you press q you will exit where you navigated to!

When this option is enabled, search command patterns are considered as globs, otherwise they are literals. You can customize copy and move operations by defining a 'paste' command. These can be useful to see the output of a program before the ui is resumed. Modal commands do not take any arguments, but instead change the operation mode to read their input conveniently, and so they are meant to be assigned to keybindings. 'f'). You may instead divide it to multiple lines in between double quotes by escaping newlines with backslashes as follows: Having such a long variable definition in a shell configuration file might be undesirable. You can set the number of keys to match using 'findlen' option. We can move it outside of the command so it would only run once at startup: Since these are one liners, we can drop '{{' and '}}': Finally note that we set 'IFS' variable manually in these commands.

So now you can display a message in the current client by calling the following in a shell command: Since lf does not have control flow syntax, remote commands are used for such needs. If this variable is set in the environment, use the same value, otherwise set the value to 'sh' on Unix, 'cmd' in Windows. Your system may already come with a preview filter named 'lesspipe'. Note that input is line buffered and output and error are byte buffered.
