Top Forums UNIX for Dummies Questions & Answers Why Do You Need the Explicit Pathname to Execute? Post 302738105 by sudon't on Friday 30th of November 2012 11:04:36 AM
Old 11-30-2012
I think people are misunderstanding my question, or I haven't been clear enough. (Or possibly I've misunderstood your answers?) Please forgive my ignorance, I was only wondering why, when you are in the same directory as a file, (not only executables), to access it, you only need its name.
Code:
$ anycommand any_execfile
$ anycommand any_file

But to execute a file, you must add dot-slash.
Code:
$ ./any_execfile

In other words, why doesn't simply typing the name and hitting <ENTER> work?
Code:
$ any_execfile
-bash command not found

Is it perhaps that using the pathname just indicates to the system that execution is your intention? Or that it forces you to do something extra, so you know you are executing something? Yes, that makes sense.


As a side note, I do understand what all of you have been telling me - that executables belong in protected directories, and all the very good reasons for that. I also understand why you encourage me to follow canonical unix protocols - someday I may working on something other than my own Macbook - maybe even a shell account accessed from my own Macbook at home. One should develop good habits.

You can still do so with ./ but it will be hard to claim you did so by accident.
Yes, this is what I was wondering about - the reason it's done this way, is simply that it forces you to realize what you are doing?

RAKE(1) 						 Ruby Programmers Reference Guide						   RAKE(1)

NAME
rake -- Ruby Make SYNOPSIS
rake [--f Rakefile] [--version] [-CGNPgnqstv] [-D [PATTERN]] [-E CODE] [-I LIBDIR] [-R RAKELIBDIR] [-T [PATTERN]] [-e CODE] [-p CODE] [-r MODULE] [--rules] [variable=value] target ... DESCRIPTION
Rake is a simple ruby(1) build program with capabilities similar to the regular make(1) command. Rake has the following features: o Rakefiles (Rake's version of Makefiles) are completely defined in standard Ruby syntax. No XML files to edit. No quirky Makefile syntax to worry about (is that a tab or a space?). o Users can specify tasks with prerequisites. o Rake supports rule patterns to synthesize implicit tasks. o Flexible FileLists that act like arrays but know about manipulating file names and paths. o A library of prepackaged tasks to make building rakefiles easier. OPTIONS
--version Display the program version. -C --classic-namespace Put Task and FileTask in the top level namespace -D [PATTERN] --describe [PATTERN] Describe the tasks (matching optional PATTERN), then exit. -E CODE --execute-continue CODE Execute some Ruby code, then continue with normal task processing. -G --no-system --nosystem Use standard project Rakefile search paths, ignore system wide rakefiles. -I LIBDIR --libdir LIBDIR Include LIBDIR in the search path for required modules. -N --no-search --nosearch Do not search parent directories for the Rakefile. -P --prereqs Display the tasks and dependencies, then exit. -R RAKELIBDIR --rakelib RAKELIBDIR --rakelibdir RAKELIBDIR Auto-import any .rake files in RAKELIBDIR. (default is rakelib ) -T [PATTERN] --tasks [PATTERN] Display the tasks (matching optional PATTERN) with descriptions, then exit. -e CODE --execute CODE Execute some Ruby code and exit. -f FILE --rakefile FILE Use FILE as the rakefile. -h --help Prints a summary of options. -g --system Using system wide (global) rakefiles (usually ~/.rake/*.rake ). -n --dry-run Do a dry run without executing actions. -p CODE --execute-print CODE Execute some Ruby code, print the result, then exit. -q --quiet Do not log messages to standard output. -r MODULE --require MODULE Require MODULE before executing rakefile. -s --silent Like --quiet, but also suppresses the 'in directory' announcement. -t --trace Turn on invoke/execute tracing, enable full backtrace. -v --verbose Log message to standard output (default). --rules Trace the rules resolution.
