About
The chmod command in Unix and Unix-like operating systems is used to change the access permissions of file system objects. This tool allows you to convert between octal and symbolic permission formats, which are commonly used to represent file permissions. Using this converter, you can easily translate numeric permission values into symbolic notation and vice versa, making it simpler to understand and apply the correct permissions to your files.
For example, an octal value of 755 translates to symbolic permissions of rwxr-xr-x, meaning the owner can read, write, and execute; the group can read and execute; and others can read and execute. This tool provides instant conversion, streamlining the process of setting file permissions correctly.
