About the composition of Linux command -

मान लें:

  1. फ़ाइल का पथ ~ / f
    2. < Li> "जो" च "~ / f" से पता चलता है,

फिर,

जो f | बिल्ली दिखाता है ~ / f । तो cat यहां ~ / f के उद्धरण पर लागू होता है, जो कि cat ~ / f के साथ अलग है।

मेरा प्रश्न यह है कि मैं cat ~ / f के परिणाम को प्राप्त करने के लिए जो और cat से बना एक कमांड का उपयोग कर सकता हूं? जब मुझे जो का परिणाम अग्रिम में नहीं पता है, तो इस संरचना का उपयोग बहुत सुविधाजनक हो सकता है वर्तमान में, अगर मुझे के परिणाम का पता नहीं है तो अग्रिम में, मुझे जो पहले एफ लागू करना है, और परिणाम को कॉपी करने के लिए कॉपी करें कम ।

एक संबंधित प्रश्न यह है कि मैं के परिणाम को एक चर में कैसे निर्दिष्ट करूं?

बहुत बहुत धन्यवाद!

बिल्ली "जो कि एफ <"

c# - TypeConverter in propertygrid only converts from string, not to -

Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from.
