If none of the wildcarded arguments sent to a command result in any matches, the command will not be executed. If this happens when using the shell interactively, a warning will also be printed. +Note that for most commands, if any wildcard fails to expand, the command is not executed, <a href='#variables-status'>`$status`</a> is set to nonzero, and a warning is printed. This behavior is consistent with setting `shopt -s failglob` in bash. There are exactly 3 exceptions, namely <a href="commands.html#set">`set`</a>, <a href="commands.html#count">`count`</a> and <a href="commands.html#for">`for`</a>. Their globs are permitted to expand to zero arguments, as with `shopt -s nullglob` in bash. +Examples: +\fish +ls *.foo +# Lists the .foo files, or warns if there aren't any. + +set foos *.foo +if test (count $foos) -ge 1 + ls $foos +end +# Lists the .foo files, if any. +\endfish \subsection expand-command-substitution Command substitution |
