.Sh DESCRIPTION
|
||
|
.Nm File
|
||
|
tests the specified files and attempts to classify them.
|
||
|
If a file is a text file,
|
||
|
it attempts to determine the type of text (e.g.
|
||
|
.Xr csh 1
|
||
|
commands or C source code).
|
||
|
.Pp
|
||
|
The options are as follows:
|
||
|
.Bl -tag -width Ds
|
||
|
.It Fl h
|
||
|
If a symbolic link is specified, identify the file as a symbolic
|
||
|
link.
|
||
|
By default, symbolic links are only identified if they reference
|
||
|
non-existent files.

|

|
||
|
.Sh COMPATIBILITY
|
||
|
Previous implementations of the
|
||
|
.Nm file
|
||
|
utility did not follow symbolic links by default.
|
||
|
.Sh BUGS
|
||
|
As many tests are used and
|
||
|
.Nm file
|
||
|
stops testing on the first successful one, it can often make mistakes.
