* What's the proper way to escape characters with #(command)?
* What is the proper way to escape characters with #(command)?
When using the character pair #(command), the command will be parsed twice.
First when it's read by the configuration file, or the command-prompt parser,
and another right before the command is passed to the shell by popen(3). As an
example, to echo the string (test) to the status line, one could use single,
or double-quotes (the meaning is the same as if in the shell):
When using the #(command) construction to include the output from a command in
the status line, the command will be parsed twice. First, when it's read by the
configuration file or the command-prompt parser, and second when the status
line is being drawn and the command is passed to the shell. For example, to
echo the string "(test)" to the status line, either single or double quotes
could be used:
set -g status-right "#(echo \\\\(test\\\\))"
set -g status-right '#(echo \\\(test\\\))'
With the double-quotes, the string when is first parsed will be set to
#(echo \\(test\\)), and then again parsed as echo \(test\) before passing the
command to sh -c.
In both cases, the status-right option will be set to the string "#(echo
\\(test\\))" and the command executed will be "echo \(test\)".
