\section and and - conditionally execute a command
\subsection and-synopsis Synopsis
\fish{syn}
COMMAND1; and COMMAND2
\endfish
\subsection and-description Description
`and` is used to execute a command if the current exit
status (as set by the last previous command) is 0.
`and` 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 and-example Example
The following code runs the `make` command to build a program. If the
build succeeds, `make`'s exit status is 0, and the program is installed. If either step fails,
the exit status is 1, and `make clean` is run, which removes the files created by the.
build process.
