As a special service "Fossies" has tried to format the requested text file into HTML format (style: standard) with prefixed line numbers. Alternatively you can here view or download the uninterpreted source code file. See also the latest Fossies "Diffs" side-by-side code changes report for "EXAMPLES": 2.20_vs_2.21.

   12 Usage: which [options] [--] COMMAND [...]
   13 Write the full path of COMMAND(s) to standard output.
   14 
   15   --version, -[vV] Print version and exit successfully.
   16   --help,          Print this help and exit successfully.
   17   --skip-dot       Skip directories in PATH that start with a dot.
   18   --skip-tilde     Skip directories in PATH that start with a tilde.
   19   --show-dot       Don't expand a dot to current directory in output.
   20   --show-tilde     Output a tilde for HOME directory for non-root.
   21   --tty-only       Stop processing options on the right if not on tty.
   22   --all, -a        Print all matches in PATH, not just the first
   23   --read-alias, -i Read list of aliases from stdin.
   24   --skip-alias     Ignore option --read-alias; don't read stdin.
   25   --read-functions Read shell functions from stdin.
   26   --skip-functions Ignore option --read-functions; don't read stdin.
   27 
   28 Recommended use is to write the output of (alias; declare -f) to standard
   29 input, so that which can show aliases and shell functions. See which(1) for
   30 examples.
   31 
   32 If the options --read-alias and/or --read-functions are specified then the
   33 output can be a full alias or function definition, optionally followed by
   34 the full path of each command used inside of those.
