Determining a file type with file
It is useful to know what files contain in Linux system. To do this, we will use the
file command to determine a file's type. Filenames in Linux are not required to reflect a file's contents.
While a filename like "picture.jpg" would normally be expected to contain a JPEG compressed image, it is not required to in Linux. We can invoke the
file command to see a brief description of the file's contents.
file syntax is:
$ file picture.jpg picture.jpg: JPEG image data, JFIF standard 1.01
In Linux, everything is a file. There are many kinds of files. While many of the files on your system are familiar, for example MP3 and JPEG, there are many kinds that are a little less obvious and a few that are quite strange.
There are many ways to display the contents of files, the most widely used are
tail. Here is a short tutorial about them.
