NAME
and - conditionally execute a command

SYNOPSIS
PREVIOUS; and COMMAND

DESCRIPTION

and is used to execute a command if the previous command was successful (returned a status of 0).

and statements may be used as part of the condition in an while <> or if <> block.

and does not change the current exit status itself, but the command it runs most likely will. The exit status of the last foreground command to exit can always be accessed using the $status <#variables-status> variable.

The -h or --help option displays help about using this command.

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.

    make; and make install; or make clean
