linux what type of file

[mister_v]

Hi,

I have a file, but I do not what type it is.
A pdf, jpg or another file ?

Is there a way to find out ?

You can use

Code: Select all

ls -lha filename

It shows the info about the file,

But perhaps what you are looking for is

Code: Select all

file filename

Result:

Code: Select all

file can_w33.pdf 
can_w33.pdf: PDF document, version 1.4
