The `forx` program

+ +

+forx runs a loop. +

+ +

Interface

+ +

+ In an execlineb script: +

+ +

+     forx [ -p | -x breakcodes ] variable { args... } loop...
+

+ +

forx reads a +block and unquotes it. +That block contains a list of args.
For each argument x in args..., +forx runs loop as a child process, with +variable=x added to its environment.
forx then exits 0.

+ +

Options

+ +

-p : run in parallel. Do not wait for an instance of +loop... to exit before spawning the next one. forx +will still wait for all instances of loop to terminate before +exiting, though.
-x breakcodes : breakcodes must +be a comma-separated list of exit codes. If the -p flag +hasn't been given and loop exits with one of the codes in breakcodes, +forx will not run the following instances of the loop, but exit immediately with the +same exit code.

+ +

Notes

+ +

You can start loop with "import variable unexport variable" +if you want variable substitution.
