\subsection and-description Description
`and` is used to execute a command if the current exit status (as set by the previous command) is 0.
`and` statements may be used as part of the condition in an `if` or `while` block. See the documentation for `if` and `while` for examples.
`and` does not change the current exit status. The exit status of the last foreground command to exit can always be accessed using the $status 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.
