The `background` program

+ +background launches a command in the background, then goes on +with the execution flow. + +

Interface

+ +

+ In an execlineb script: +

+ +

+     background [ -d ] { prog1... } prog2...
+

+ +

background reads a prog1... command in a +block and unquotes it.
It spawns a child executing prog1....
It sets the ! environment +variable to the pid of the prog1... process.
It then execs into prog2....

+ +

Options

+ +

-d : doublefork. If the -d option is set, +prog1... will run as a grandchild of background.

+ +

Notes

+ +

background prog1... "" prog2... is +equivalent to sh -c 'prog1... & ; exec prog2...'.

+ + + -- cgit v1.2.3
