tidypath cleans up PATH and PATH-like strings by removing duplicates and
normalizing empty fragments. Add the following, or its equivalent, to the
bottom of the appropriate startup script (e.g., ~/.profile,
~/.bash_profile) for your shell:
hash tidypath && export PATH="`tidypath`"
tidypath uses the GNU build system. To build directly from the github source,
you'll need Autoconf, Automake, and Libtool. Execute the following ($
represents the shell prompt):
$ git clone https://github.com/jneu/tidypath.git
$ cd tidypath
$ ./prep_build.bash
$ ./configure
$ make
$ make check
$ sudo make install
If you received tidypath as a tarball, you don't need the GNU build tools.
Instead, execute the following:
$ tar xzf tidypath-0.0.9.tar.gz # Your version may be different
$ cd tidypath-0.0.9
$ ./configure
$ make
$ make check
$ sudo make install
Standard configure options are supported. E.g, to install tidypath in a
specific directory, use something like:
$ configure --prefix=/home/your_user_name/local
By default, tidypath does not free any internally allocated memory as it's
not necessary to do so and slows down program execution. When developing or
troubleshooting, it's useful to change this behavior. To insure all memory is
deallocated, use:
$ configure --enable-free
PATH variables are notorious for becoming large and unwieldy. tidypath cleans
up PATH and PATH-like strings by removing duplicate entries and changing all
empty fragments into .. Typical usage would be to add something like the
following to the appropriate shell startup script:
hash tidypath && export PATH="`tidypath`"
Other examples:
$ export PATH=/usr/bin:/usr/local/bin:/bin:/usr/local/bin:
$ tidypath
/usr/bin:/usr/local/bin:/bin:. # No newline
$ tidypath "$PATH" # Equivalent to the above
$ tidypath --env PATH # Equivalent to the above
$ tidypath --env CLASSPATH # Operate on $CLASSPATH instead
$ tidypath --aggressive # _Really_ clean up $PATH
tidypath supports command line options:
tidypath [options] [pathlike_string (defaults to $PATH)]
-a, --aggressive also prune absolute fragments that match previous
inodes, do not exist, or are not directories
-d, --delimiter <char> specify the delimiter to use; defaults to :
-e, --env the first argument will specify the name of an
environment variable to use
-h, --help show this help message and exit
-i, --ignore-empty prune empty fragments
-n, --nop do not prune any fragments for any reason
-p, --pretty print each fragment separated by a newline
-V, --version show the version of tidypath and exit
