Chmod 755 - rwxr-xr-x Permission Breakdown
Chmod 755 equals rwxr-xr-x in symbolic notation. Owner full access; group and others read/execute. Use case: Executable scripts, directories, and CLI tools. Toggle bits below, see security warnings, and copy chmod 755 commands for your path.

Chmod 755 FAQ
What does chmod 755 mean?
Octal 755 maps to rwxr-xr-x. Owner full access; group and others read/execute. Typical use: Executable scripts, directories, and CLI tools. Each digit encodes owner, group, and others permissions using read=4, write=2, execute=1, so you can rebuild the mode from individual rwx bits when auditing a deployment or fixing a broken upload script.
What is rwxr-xr-x in octal?
Symbolic rwxr-xr-x converts to octal 755. Owner digits come first, then group, then others. This page loads the calculator with 755 pre-selected so you can inspect or tweak individual bits and copy a ready chmod command for your path before you deploy.
When should I use chmod 755?
Executable scripts, directories, and CLI tools Always verify against your deployment checklist and security policy before applying the mode recursively in production. Use the calculator above to preview symbolic notation and warnings, then copy the exact chmod command for your path.
How do I run chmod 755 in the terminal?
Execute chmod 755 path/to/file for a single file, or chmod 755 -R directory/ recursively. Confirm the path first - recursive chmod on the wrong folder is difficult to undo. Copy the command from the calculator output above, then re-run ls -l to confirm rwxr-xr-x.
Chmod 755 vs ls -l output: how do they relate?
ls -l shows symbolic permissions on the left (e.g., rwxr-xr-x) and may omit octal. This calculator bridges both views. 755 is typical for directories and shell scripts. Match every rwx character before you ship.
Where is the full chmod calculator?
The main Chmod Calculator supports any 3-digit octal value and interactive rwx toggles with live security warnings. Visit /dev-tools/chmod-calculator/ for the complete tool with methodology, related modes, and Dev Tools cross-links when you need a mode outside this named preset page.
