Is chmod 134 Safe?

Moderate

Every member of the group can modify this file.
Any user can read this file — never use it for secrets such as keys or .env files.
Even the owner cannot modify this file without changing permissions first.
Scripts need read permission to run; only compiled binaries can be executed without it.
Unusual: a lower class has permissions the class above it lacks.

Common Use Cases

134 is uncommon in standard Linux setups. The closest widely used permission is chmod 775.

chmod 134 Command Examples

# Apply using octal mode
chmod 134 filename

# Apply using equivalent symbolic mode
chmod u=x,g=wx,o=r filename

# Recursive command warning:
chmod -R 134 /path/to/dir
# Note: -R applies the same mode to files and directories. Use find to treat them separately:
find /path/to/dir -type d -exec chmod 134 {} +

# Verify permissions
stat -c '%a %A %n' filename    # Linux
stat -f '%Lp %Sp %N' filename   # macOS

# Example ls -l output:
---x-wxr-- 1 alice staff 1024 Jan 15 10:00 example.txt
