$ScriptInputString—Wolfram Documentation
represents input given on the standard input channel to the original operating system command with which the current instantiation of the Wolfram Language was invoked.
Details
- If the Wolfram Language kernel is invoked via a wolframscript mechanism, the $ScriptInputString contains all input given on standard input.
- If the Wolfram Language kernel is run in a way other than via a wolframscript mechanism, the $ScriptInputString gives None.
Examples
Basic Examples (1)
$ScriptInputString is set to None in an interactive session:
$ScriptInputStringFind the wolframscript executable:
wolframscript = "!\"" <> FileNameJoin[{$LaunchDirectory, "wolframscript"}] <> "\"";Set up appropriate arguments for the operating system:
args = If[$OperatingSystem == "Windows", " -code $ScriptInputString", " -code '$ScriptInputString'"];$ScriptInputString is set to an empty string in this case, as standard input is empty:
Import[wolframscript <> args, "Text"]Text
