Shell ek computer operating system ka important component hota hai jo user aur operating system ke beech communication aur interaction ko facilitate karta hai. Shell, user ke dvara diye gaye commands ko interpret karke unhe operating system ke kernel tak pahunchata hai aur kernel se output ko user tak pahunchata hai. Shell ek command-line interface (CLI) ya graphical user interface (GUI) ke roop mein ho sakta hai. Niche, main kuch important points aur concepts ke bare mein batata hoon:
Shell in linux in hindi – Linux OS in hindi
Aaj hum iss post me padhenge ki Shell kya hota hain linux me Uske kitne types hote hain , command interpretation kya hai, prompt kya hota hai, command history, Scripting, Variables, Redirection, Pipes, Environment variables kya hota hai ye sb janenge or janenge ki Advantages kya hote hain, Disadvantages, Featuures or uses kya kya hote hain hindi me.
- Command Interpretation: Shell user ke dvara diye gaye commands ko read karke unhe execute karta hai. Commands operating system ke functions aur utilities ko invoke karte hain. Example of a command:
ls(list files and directories). - Prompt: Shell aksar ek prompt provide karta hai, jahan par user apne commands likh sakta hai. Prompt usually ek text string hota hai jo command-line ke samne dikhata hai, jaise ki
$(in Unix-like shells) yaC:\>(in Windows Command Prompt). - Command History: Shells aksar command history maintain karte hain. Isse user apne previously executed commands ko dekh sakta hai, unmein se kuch ko dubara chala sakta hai aur unhein modify karke dobara use kar sakta hai.
- Scripting: Shells scripting languages bhi hote hain, jinse user apne commands ko automate kar sakte hain aur scripts likh sakte hain. Yeh scripts multiple commands ko ek sath execute karne mein madad karte hain.
- Variables: Shells variables ko support karte hain. User variables create karke unmein data store kar sakte hain aur phir un data ko commands ke andar use kar sakte hain.
- Redirection: Shell commands ki output ko redirection kiya ja sakta hai, matlab ki output ko file mein store kiya ja sakta hai ya dusre command ko pass kiya ja sakta hai. Isse data processing aur file handling mein madad milti hai.
- Pipes: Shell pipes ka bhi support karta hai, jisse ek command ki output dusre command ke input mein di ja sakti hai. Example:
ls | grep ".txt"(list all files with “.txt” in their names). - Environment Variables: Shells environment variables ko manage karte hain. Yeh system-wide variables hote hain jo commands ke liye important information store karte hain.
Kuch popular Unix-like shells hain:
- Bash (Bourne Again Shell): Bash ek bahut common shell hai jo Unix-like operating systems mein aksar default shell hoti hai. Yeh scripting ke liye bhi popular hai.
- Zsh (Z Shell): Zsh ek powerful shell hai jo Bash ki capabilities ko extend karti hai aur scripting, customization, aur tab completion ke liye prasiddh hai.
- Fish (Friendly Interactive Shell): Fish ek user-friendly shell hai jo auto-suggestions aur syntax highlighting provide karti hai, jisse beginners ke liye bhi acchi choice hai.
- Ksh (Korn Shell): Ksh ek commercial shell hai jo Unix aur Unix-like operating systems ke liye available hai. Isme advanced scripting capabilities hoti hain.
- Dash: Dash ek minimalist shell hai jo POSIX standards ko follow karti hai. Yeh Linux distributions mein aksar /bin/sh ke roop mein use hoti hai.
Shell user aur operating system ke beech ek important bridge ka kaam karti hai aur users ko system ke resources aur utilities tak access dene mein madad karti hai.
Advantages of Shell in linux in hindi – Linux OS in hindi:-
Linux mein “shell” ek command line interface hai jo user ko operating system se interact karne ki anumati deta hai. Shell commands ke dwara user files ko manage kar sakta hai, programs ko chalane ke liye instructions de sakta hai, aur system settings ko configure kar sakta hai.
