Yeh chmod calculator Unix aur Linux file permissions ko octal aur symbolic rwx notation ke beech convert karta hai, bina aapko math yaad karwaaye. Owner, group aur others ke liye read, write aur execute checkboxes toggle karein aur turant matching octal value (jaise 644 ya 755), symbolic string (rw-r--r--), aur exact chmod command dekhein jise aap apne terminal mein paste kar sakte hain. Aap seedhe 3 ya 4 digit ka octal number bhi type kar sakte hain, special bits samet, aur permission grid ko real time mein update hote dekh sakte hain. Yeh developers, sysadmins aur DevOps engineers ke liye banaya gaya hai jo servers, deploy scripts, SSH keys aur web directories par file modes set karte hain, aur jab aap samajhna chahte hain ki chmod 644 ka matlab kya hai ya scratch se ek unix file permissions string banana chahte hain, tab yeh ek quick reference ki tarah bhi kaam aata hai. Sab kuch pura aapke browser mein chalta hai, isliye aapka input locally process hota hai aur kabhi aapke device se bahar nahi jaata.
Features
Owner, group aur others ke liye read, write aur execute ka interactive permission grid
Octal (jaise 755) aur symbolic rwx notation ke beech live two-way conversion
3 ya 4 digit ka octal value, jaise 755 ya 4755, type karke grid turant bharein
rwxr-xr-x jaisa pura 9-character symbolic permission string dikhata hai
Setuid, setgid aur sticky bit bhi handle karta hai, jo ls -l ki tarah s, S, t ya T dikhte hain
Checkboxes toggle karte hi results live update hote hain, koi submit step nahi
chmod Calculator kaise use karein
Owner, group aur others ke read, write aur execute boxes check karein, aur special bit chahiye to setuid, setgid ya sticky bhi.
Grid ke neeche dikhne wali octal value aur symbolic rwx string padhein.
Ya Octal field mein 644 ya 4755 jaisa octal number type karein, ya Symbolic field mein ls -l ki string paste karein.
Generated command copy karein, "file" ki jagah apni file ka path daalein, aur use terminal mein run karein.
Example
Input
rw-r--r--
Output
644
chmod 644 file
Owner ko symbolic read/write aur group aur others ko read-only, octal 644 par map hota hai.
Common errors aur troubleshooting
Octal field mein 7 se badi digit type karna, jaise 844. — Har permission digit 0-7 honi chahiye kyunki yeh read (4), write (2) aur execute (1) ka sum hai. 644 ya 755 jaisi values use karein.
Symbolic output mein d ya - jaise leading file-type character ki ummeed karna. — Tool sirf 9-character permission string (rwxr-xr-x) dikhata hai, kyunki ls -l ka type flag chmod mode ka hissa nahi hota. Phir bhi aap drwxr-xr-x jaisi poori ls -l string paste kar sakte hain; type letter ignore ho jaata hai.
777 ko web files ke liye safe default samajhna. — 777 sabko write aur execute deta hai, jo ek security risk hai. Zyadatar cases mein files ke liye 644 aur directories ya scripts ke liye 755 use karein.
rwSr--r-- jaisa capital S ya T dikhna. — Capital S ya T ka matlab hai ki special bit set hai lekin uske neeche ka execute bit nahi, jo aksar galti hoti hai: 4644 rwSr--r-- dikhta hai. Us class ke liye Execute tick karein taaki lowercase s ya t mile, jaise 4755 (rwsr-xr-x).
Sochna ki chmod 644 script ko non-executable kyun chhod deta hai. — 644 mein koi execute bit nahi hota. 755 (rwxr-xr-x) use karein taaki owner script run kar sake jabki group aur others usse read aur execute kar sakein.
Aksar pooche jaane wale sawaal
Chmod calculator kya hai aur yeh kya karta hai?
Chmod calculator Unix file permissions ko octal numbers (jaise 644) aur symbolic rwx notation (jaise rw-r--r--) ke beech convert karta hai. Yeh exact chmod command bhi generate karta hai taaki aap apne terminal mein mode apply kar sakein.
Chmod 644 ka matlab kya hai?
644 owner ko read aur write (rw-) deta hai, aur group aur others ko read-only (r--). Chmod calculator mein yeh symbolic string rw-r--r-- ki tarah dikhta hai, jo regular files ke liye common hai.
rwxr-xr-x jaisi symbolic permissions ko octal mein kaise convert karein?
Grid mein matching read, write aur execute boxes toggle karein aur chmod calculator octal value dikhata hai, is case mein 755. Har digit read (4), write (2) aur execute (1) ka sum hoti hai.
755 versus 644 kab use karna chahiye?
Directories aur executable scripts ke liye 755 use karein taaki unhe enter ya run kiya ja sake, aur normal files ke liye 644 jinhe executable nahi hona chahiye. Calculator dono ke liye exact chmod command generate karta hai.
Kya chmod calculator setuid, setgid ya sticky bit handle karta hai?
Haan. Setuid (4), Setgid (2) ya Sticky (1) tick karein, ya 4755, 2775 ya 1777 jaisa 4-digit mode type karein. Symbolic string inhe ls -l ki tarah dikhati hai, execute slot mein s ya t (execute off ho to S ya T), aur command chmod 4755 file ban jaata hai.
Haan. Chmod calculator pura aapke browser mein chalta hai, isliye aap jo values enter karte hain woh locally process hoti hain aur kabhi aapke device se bahar nahi jaati.
