Frequently asked questions
What does chmod 755 mean?
Owner can read, write, and execute (7); group and others can read and execute (5 each). Toggle the checkboxes or type the octal to see both forms.
How do I copy a chmod command?
Set the permissions you want, then click Copy to put something like chmod 755 file on your clipboard.
Can I type octal instead of checkboxes?
Yes. Enter a three-digit octal (for example 644 or 777) and the owner/group/other bits update automatically.
Is my input uploaded?
No. TryDevSnip calculates permissions in your browser. Nothing you enter is uploaded to our servers for processing.
