file: Allow file to work with special or device files.
$ file -s ${filename}
try on your machine
The command "file -s ${filename}" is used to determine the file type and other details of a file specified by the variable "${filename}".
Here's how it works:
- The "file" command is a standard Unix/Linux utility that analyzes the given file and provides information about its type.
- The "-s" option is used to read the file system specified by "${filename}" and report the content type. It attempts to determine the file type by looking at the file's contents or metadata rather than relying on the file extension.
- "${filename}" is a placeholder for the actual file name you want to analyze. It should be replaced with the name or path of the file you want to examine.
By executing this command, the system will analyze the specified file and provide details such as the file type, including whether it is a text file, binary file, image, audio, etc. It helps in identifying the format of unknown or unlabeled files.
