getcap:tldr:a0aec

The command "getcap ${filename1 filename2 ---}" is a Linux command used to check the capabilities of one or more files or directories. Here's a breakdown of what each part of the command represents:

• "getcap" is the name of the command, which stands for "get capabilities".
• "${filename1 filename2 ---}" is a placeholder for the name(s) of the file(s) or directory(ies) you want to check. "filename1" and "filename2" are just examples and should be replaced with the actual names of the files you want to check. "---" is used to indicate the end of the filenames list if there are more than two files.

By executing this command, you can retrieve the capabilities associated with the specified files or directories, if there are any. File capabilities are a set of attributes that can be assigned to executable files or directories to grant them specific privileges without giving full root access. These capabilities can include permissions such as reading specific files, binding to reserved ports, or elevating privileges for specific operations.
