关于chmod 计算器
A chmod calculator converts Unix/Linux file modes between octal numbers and symbolic notation—handy when you need to know what 755 means or turn rwxr-xr-x into a number.
Toggle Read / Write / Execute for owner, group, and other, plus optional setuid, setgid, and sticky bits. Octal and symbolic inputs stay in sync, and you get a ready-to-copy `chmod 755 file` command.
It understands s/S/t/T special-bit letters and an optional `ls -l` file-type prefix (`-rwxr-xr-x`). Everything runs locally in your browser.
使用方法
- Check owner / group / other permissions
- Optionally enable setuid / setgid / sticky
- Copy octal, symbolic, or the chmod command
常见问题
Are 755 and rwxr-xr-x the same?
Yes. Owner rwx (7) and group/other r-x (5) make both 755 and rwxr-xr-x equivalent.
What are setuid, setgid, and sticky?
Special bits: setuid (4000) runs as the file owner, setgid (2000) runs as the group or inherits group on directories, and sticky (1000) restricts deletion in a directory to each file's owner.
What do s and t mean in symbolic mode?
When execute and a special bit are both on, the x slot shows s (setuid/setgid) or t (sticky). If the special bit is on without execute, you get uppercase S or T.
Is my data sent externally?
No. Conversion runs entirely in your browser; nothing is sent to toco.tools servers.
