    The following form allows you to view linux man pages.

    Command:

    which

    
    
    

    SYNOPSIS

           which [options] [--] programname [...]
    
    
    

    DESCRIPTION

           Which takes one or more arguments. For each of its arguments it prints
           to stdout the full path of the executables that would have been exe-
           cuted when this argument had been entered at the shell prompt. It does
           this by searching for an executable or script in the directories listed
           in the environment variable PATH using the same algorithm as bash(1).
    
           This man page is generated from the file which.texinfo.
    
    
    

    OPTIONS

           --all, -a
               Print all matching executables in PATH, not just the first.
    
           --read-alias, -i
               Read aliases from stdin, reporting matching ones on stdout. This is
               useful in combination with using an alias for which itself. For
               example
               alias which=?alias | which -i?.
    
           --skip-alias
               Ignore option `--read-alias?, if any. This is useful to explicity
               search for normal binaries, while using the `--read-alias? option
               in an alias or function for which.
    
           --read-functions
               Read shell function definitions from stdin, reporting matching ones
               on stdout. This is useful in combination with using a shell func-
               tion for which itself.  For example:
               which() { declare -f | which --read-functions $@ }
               export -f which
    
           --skip-functions
               Ignore option `--read-functions?, if any. This is useful to explic-
               ity search for normal binaries, while using the `--read-functions?
               option in an alias or function for which.
    
           --skip-dot
               Skip directories in PATH that start with a dot.
    
           --skip-tilde
               Skip directories in PATH that start with a tilde and executables
               which reside in the HOME directory.
    
           --show-dot
               If a directory in PATH starts with a dot and a matching executable
               was found for that path, then print "./programname" rather than the
               full path.
    
           --show-tilde
           Which returns the number of failed arguments, or -1 when no `program-
           name? was given.
    
    
    

    EXAMPLE

           The recommended way to use this utility is by adding an alias (C shell)
           or shell function (Bourne shell) for which like the following:
    
           [ba]sh:
    
                which ()
                {
                  (alias; declare -f) | /usr/bin/which --tty-only --read-alias --read-functions --show-tilde --show-dot $@
                }
                export -f which
    
           [t]csh:
    
                alias which ?alias | /usr/bin/which --tty-only --read-alias --show-dot --show-tilde?
    
           This  will  print  the readable ~/ and ./ when starting which from your
           prompt, while still printing the full path when used from a script:
    
                > which q2
                ~/bin/q2
                > echo `which q2`
                /home/carlo/bin/q2
    
    
    

    BUGS

           The HOME directory is determined by looking for  the  HOME  environment
           variable,  which  aborts  when this variable doesn?t exist.  Which will
           consider two equivalent directories to be different when  one  of  them
           contains a path with a symbolic link.
