Command language, Command structure, Shell in Linux In Hindi

Command Language, Command Structure, aur Shell, computer operating systems mein commands ko interpret aur execute karne ke liye important concepts hain. Niche main in tino concepts ko detail mein explain kar raha hoon:

Command language, Command structure, Shell in Linux In Hindi

1. Command Language (Command Bhasha):

  • Command Language ek specific syntax aur grammar ka collection hota hai, jise computer ko commands dene ke liye istemal kiya jata hai.
  • Ye language computer ya operating system ko instructions dene ke liye use hoti hai, jaise ki files ko create karna, delete karna, directories ko navigate karna, aur applications ko run karna.
  • Command Language platform-specific hoti hai, matlab ki har operating system apni command language ka istemal karta hai. For example, Unix-like operating systems (including Linux) command language mein Unix Shell commands ka istemal karte hain.

2. Command Structure (Command Banawat):

  • Command Structure us tarah ka arrangement hota hai jisse command language me di gayi commands ko likha jata hai.
  • A typical command structure consists of the following parts:
  • Command Name: Ye batata hai ki kaunsa specific command execute kiya ja raha hai, jaise ls, mkdir, ya cp.
  • Options (Flags): Optional hote hain aur command ke behavior ko modify karte hain, jaise -l, -a, ya --help.
  • Arguments (Arguments): Mandatory hote hain aur command ke specific task ko specify karte hain, jaise filenames, directories, aur other parameters.
  • Syntax: Har command ka apna syntax hota hai, jisse aapko follow karna hota hai. Syntax batata hai ki kaise command likhni hai, jaise ki command_name -option argument.

3. Shell:

  • Shell ek command interpreter hota hai, jo command language ke commands ko interpret karta hai aur unhe operating system ke kernel tak pahunchata hai.
  • Shell user interface ka ek important part hota hai, jiska madhyam se users commands ko enter karke system se interact karte hain.
  • Popular Unix-like operating systems (jaise ki Linux) me kai alag-alag shells available hote hain, jaise ki Bash, Zsh, aur Fish. Har shell apne unique features aur customization options ke liye prasiddh hoti hai.
  • Shell scripting bhi ek common practice hai, jisme users apne tasks ko automate karne ke liye scripts likhte hain, jo ek series of commands ko execute karte hain.

Samanya roop se, command language ka istemal shell ke andar hota hai. User shell ke through command likhta hai, shell use interpret karta hai, aur phir us command ko operating system ke kernel tak pahunchata hai, jisse desired action execute ho.
