\section or or - conditionally execute a command
\subsection or-synopsis Synopsis
\fish{syn}
COMMAND1; or COMMAND2
\endfish
\subsection or-description Description
`or` is used to execute a command if the current exit
status (as set by the last previous command) is not 0.
`or` does not change the current exit status.
The exit status of the last foreground command to exit can always be
accessed using the <a href="index.html#variables-status">$status</a>
variable.
\subsection or-example Example
The following code runs the `make` command to build a program. If the
build succeeds, the program is installed. If either step fails,
`make clean` is run, which removes the files created by the
build process.
\fish
make; and make install; or make clean
\endfish
