How do I use symbolic mode with chmod in Linux?

You can use symbolic mode with chmod by specifying the permissions you want to add or remove. For example, 'chmod u+x file.txt' adds execute permission for the user.

What do the symbols u, g, and o stand for?

In chmod, 'u' stands for user, 'g' for group, and 'o' for others. You can modify permissions for each of these.

Can I remove permissions as well?

Yes, you can remove permissions using the '-' symbol. For example, 'chmod g-w file.txt' removes write permission from the group.

What if I want to set permissions for all users?

You can use 'a' for all users. For example, 'chmod a+r file.txt' gives read permission to everyone.
