Use terminal command in ruby code?

Question

Is there any way to use command line commands in ruby code ?

Like : Some third party .ipa installer command inside ruby code(reinstall the app between scenarios using a 3rd party installer like ideviceinstaller).

Answer 1

• Kernel#exec, that replaces your ruby process with the one you specified, as a corresponding syscall. Therefore, it ends the program even if there's more code to run. Probably not what you want. Works like: exec("this")
• Backticks. `this` will run this and return its stdout as a string. The same thing with different syntax: %x(this)
• Kernel#system: mostly same as exec, but doesn't replace your Ruby process and returns a boolean... most of the time: whether it worked successfully (true), it returned non-zero (false) or failed to run at all (nil); runnable as system("this")
