# chmod 775 — What It Means & When to Use It

> Owner and group can do everything; others can read and execute. Symbolic: `rwxrwxr-x` · Use with care.

775 is 755 with write access added for the group. Everyone in the file's group can create, rename and delete entries in the directory, while other users can still list and enter it but not change anything.

It's the usual mode for directories that a team — or a user and a service — maintain together.

## Permission by permission

| Who | Permissions |
|---|---|
| owner | read, write and execute |
| group | read, write and execute |
| others | read and execute |

Symbolic chmod argument: `u=rwx,g=rwx,o=rx`

## Use it for

- Project directories shared by a group of developers.
- Folders that both a deploy user and the web server's group must write to.
- Combined with setgid (`2775`) so new files inherit the directory's group.

## Avoid it for

- If others shouldn't even see the contents, use `770`.
- Files usually don't need execute: use `664` for shared files that aren't scripts.

## FAQ

### What's the difference between 775 and 755?

Group write. With 775 group members can add, change and delete files in the directory; with 755 only the owner can.

### Should I use 775 or 2775 for a shared folder?

2775. The setgid bit makes new files and subdirectories inherit the folder's group, so everything stays shared instead of taking on each creator's personal group.
