Checking file owner permissions

Question

You can use stat to get the file permissions, and parse them with another command to get the character you want.

stat -c %A someFile

Returns something like:

-rw-rw-r--

EDIT: Here you go:

stat -c %A someFile | sed 's/...\(.\).\+/\1/'

Returns either - or x if the owner has execute.

EDIT 2: For completion’s sake:

if [ `stat -c %A someFile | sed 's/...\(.\).\+/\1/'` == "x" ] 
then
  echo "Owner has execute permission!"
fi

EDIT 3: If you prefer numerical permissions:

stat -c %a /path/to/a/file will output 600 or 700 or whatever 3 digit base-8 number.
