Why translate to English?

Auditing scripts, explaining permissions to colleagues, writing documentation. `chmod 644` becomes 'owner can read and write, everyone else can only read'.

Does it warn about dangerous permissions?

Yes — world-writable files (x77), world-executable directories (77x), and setuid root get explicit warnings. Common security mistakes flagged on sight.

Out of scope — this tool handles POSIX mode bits only. For Linux POSIX ACLs or Windows DACLs, use platform-specific tools.

Can it explain symbolic notation too?

Yes — `u+x` explains as 'add execute permission for the owner'. Round-trip with the Chmod Calculator for the full picture.

Input

Output

755 on a file means:

  The owner can read it, change it and run it as a program.
  Members of the group can read it and run it as a program.
  Everyone else can read it and run it as a program.

Octal:    755
Symbolic: rwxr-xr-x
Command:  chmod 755 path/to/file

Common modes:
  644  rw-r--r--  normal file — owner edits, everyone reads
  755  rwxr-xr-x  script or directory — owner edits, everyone runs or enters
  600  rw-------  private file such as an SSH key or .env
  700  rwx------  private directory
  664  rw-rw-r--  file shared with a team group
  777  rwxrwxrwx  everyone can do anything — avoid

Fun Facts

Unix file permissions were designed by Ken Thompson and Dennis Ritchie for the first Unix system at Bell Labs in 1971.
The permission value 777 grants full access to everyone and is often called 'the lazy developer's chmod' by sysadmins.
The sticky bit (1000) was originally used to keep program text in swap space for faster loading; today it prevents users from deleting others' files in /tmp.
