\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.
|
|
|
