and - conditionally execute a command¶
Synopsis¶
COMMAND1; and COMMAND2
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 variable.
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
