env_parallel - export environment to GNU parallel


********
SYNOPSIS
********


\ **env_parallel**\  [--record-env|--session|--end-session]
  [options for GNU Parallel]


***********
DESCRIPTION
***********


\ **env_parallel**\  is a shell function that exports the current environment to GNU \ **parallel**\ .

If the shell function is not loaded, a dummy script will be run instead that explains how to install the function.

\ **env_parallel**\  is 100 ms slower at startup than pure GNU \ **parallel**\ , and takes up to 30% longer to start a job (typically 15 ms).

Due to the problem with environment space (see below) you are recommended only to transfer the environment that you need.

To help you do that, you can mark names that should not be transferred. This can be done with either \ **--session**\  or \ **--record-env**\ .


.. code-block:: perl

   # Record the "clean" environment (this only needs to be run once)
   env_parallel --record-env
 
   # Optionally edit ~/.parallel/ignored_vars (only needed once)
 
   # Define whatever you want to use
   myfunc() { myalias and functions $myvar work. $1.; }
   alias myalias='echo Aliases'
   myvar='and variables'
 
   # Use --env _ to only transfer the names not in the "empty" environment
   env_parallel --env _ -S localhost myfunc ::: Hooray


Or:


.. code-block:: perl

   # Do --record-env into $PARALLEL_IGNORED_NAMES
   env_parallel --session
 
   # Define whatever you want to use
   myfunc() { myalias and functions $myvar work. $1.; }
   alias myalias='echo Aliases'
   myvar='and variables'
 
   # env_parallel will not export names in $PARALLEL_IGNORED_NAMES
   env_parallel -S localhost myfunc ::: Hooray
 
   # Optionally
   env_parallel --end-session


In \ **csh**\  \ **--session**\  is not supported:


.. code-block:: perl

   # Record the "clean" environment - this only needs to be run once
   env_parallel --record-env
 
   # Optionally edit ~/.parallel/ignored_vars - only needed once
 
   # Define whatever you want to use
   alias myalias 'echo Aliases $myvar \!*.'
   set myvar='and variables'
 
   # Use --env _ to only transfer the names not in the "empty" environment
   env_parallel --env _ -S localhost myalias ::: work


Environment space
=================


By default \ **env_parallel**\  will export all environment variables, arrays, aliases, functions and shell options (see details for the individual shells below).

But this only works if the size of the current environment is smaller than the maximal length of a command and smaller than half of the max if running remotely. E.g. The max size of Bash's command is 128 KB, so \ **env_parallel**\  will fail if '\ **set | wc -c**\ ' is bigger than 128 KB. Technically the limit is in execve(1) which IPC::open3 uses.

Bash completion functions are well-known for taking up well over 128 KB of environment space and the primary reason for causing \ **env_parallel**\  to fail.

Instead you can use \ **--env**\  to specify which variables, arrays, aliases and functions to export as this will only export those with the given name. Or follow the recommended usage in shown in DESCRIPTION.



*******
OPTIONS
*******


Same as GNU \ **parallel**\  in addition to these:


- \ **--end-session**\ 
 
 Undo last \ **--session**\ 
 


- \ **--record-env**\ 
 
 Record all names currently defined to be ignored every time running \ **env_parallel**\  in the future.
 


- \ **--session**\ 
 
 Ignore all names currently defined. Aliases, variables, arrays, and functions currently defined will not be transferred.
 
 But names defined \ *after*\  running \ **parallel --session**\  \ *will*\  be transferred.
 
 This is only valid in the running shell, and can be undone with \ **parallel --end-session**\ .
 
 You can run multiple \ **--session**\  inside each other:
 
 
 .. code-block:: perl
 
    env_parallel --session
    var=not
    # var is transferred
    env_parallel -Slocalhost 'echo var is $var' ::: ignored
    env_parallel --session
    # var is not transferred
    env_parallel -Slocalhost 'echo var is $var' ::: ignored
    env_parallel --end-session
    # var is transferred again
    env_parallel -Slocalhost 'echo var is $var' ::: ignored

Ash
===


Installation
------------


Put this in $HOME/.profile:


.. code-block:: perl

   . env_parallel.ash


E.g. by doing:


.. code-block:: perl

   echo '. env_parallel.ash' >> $HOME/.profile



Supported use
-------------


\ **--env**\  is supported to export only the variable, or alias with the given name. Multiple \ **--env**\ s can be given.

\ **--session**\  is supported.


- aliases
 
 
 .. code-block:: perl
 
    alias myecho='echo aliases'
    env_parallel myecho ::: work
