\section command command - run a program
\subsection command-synopsis Synopsis
<tt>command COMMANDNAME [OPTIONS...]</tt>
<tt>command [OPTIONS] COMMANDNAME [ARGS...]</tt>
\subsection command-description Description
\c command forces the shell to execute the program \c COMMANDNAME and ignore any functions or builtins with the same name.
\subsection command-example Example
The following options are available:
- \c -h or \c --help prints help and then exits.
- \c -s or \c --search returns the name of the disk file that would be executed, or nothing if no file with the specified name could be found in the <tt>$PATH</tt>.
With the \c -s option, \c command treats every argument as a separate command to look up and sets the exit status to 0 if any of the specified commands were found, or 1 if no commands could be found.
For basic compatibility with POSIX <tt>command</tt>, the \c -v flag is recognized as an alias for <tt>-s</tt>.
\subsection command-example Examples
<tt>command ls</tt> causes fish to execute the \c ls program, even if an 'ls' function exists.
<tt>command -s ls</tt> returns the path to the \c ls program.

@ -19,11 +19,17 @@ The following options are available:
- <code>-u</code> or <code>--unexport</code> prevents the variables from being exported to child processes (default behaviour).
- <code>-U</code> or <code>--universal</code> causes the specified shell variable to be made universal.
- <code>-x</code> or <code>--export</code> exports the variables to child processes.
- <code>-a</code> or <code>--array</code> stores the result as an array.
\c read reads a single line of input from stdin, breaks it into tokens
based on the <tt>IFS</tt> shell variable, and then assigns one
token to each variable specified in <tt>VARIABLES</tt>. If there are more
tokens than variables, the complete remainder is assigned to the last variable.
As a special case, if \c IFS is set to the empty string, each character of the
input is considered a separate token.
If \c -a or \c --array is provided, only one variable name is allowed and the
tokens are stored as an array in this variable.
See the documentation for \c set for more details on the scoping rules for
variables.

@ -12,9 +12,10 @@ The following options are available:
- \c -h or \c --help prints help and then exits.
- \c -a or \c --all prints all of possible definitions of the specified names.
- \c -f or \c --no-functions suppresses function and builtin lookup.
- \c -t or \c --type prints <tt>keyword</tt>, <tt>function</tt>, <tt>builtin</tt>, or <tt>file</tt> if \c NAME is a shell reserved word, function, builtin, or disk file, respectively.
- \c -t or \c --type prints <tt>function</tt>, <tt>builtin</tt>, or <tt>file</tt> if \c NAME is a shell function, builtin, or disk file, respectively.
- \c -p or \c --path returns the name of the disk file that would be executed, or nothing if 'type -t name' would not return 'file'.
- \c -P or \c --force-path returns the name of the disk file that would be executed, or nothing no file with the specified name could be found in the <tt>$PATH</tt>.
- \c -P or \c --force-path returns the name of the disk file that would be executed, or nothing if no file with the specified name could be found in the <tt>$PATH</tt>.
- \c -q or \c --quiet suppresses all output; this is useful when testing the exit status.
\c type sets the exit status to 0 if the specified command was found,
and 1 if it could not be found.
