Description Karel Srot 2012-02-27 10:17:43 UTC 
Description of problem:

manpage says:
The information identifying these files is read from the compiled magic
file /usr/share/misc/magic.mgc, or the files in the directory
/usr/share/misc/magic if the compiled file does not exist. In addition,
if $HOME/.magic.mgc or $HOME/.magic exists, it will be used in preference
to the system magic files.

# cat > .magic
0 string ABCDEFGH Alphabet file
# echo ABCDEFGHIJ > testfile
# file testfile 
testfile: Alphabet file
# file -C -m .magic
# ls -l .magic.mgc 
-rw-r--r--. 1 root root 400 Feb 27 05:11 .magic.mgc
# rm .magic
rm: remove regular file `.magic'? y
# file testfile 
testfile: ASCII text


Version-Release number of selected component (if applicable):
# rpm -q file
file-5.04-11.el6.x86_64


How reproducible:
always


  
Actual results:
$HOME/.magic.mgc is ignored


Expected results:
$HOME/.magic.mgc is not ignored or the manpage is updated
