=head2 Transferring environment variables and functions
|
||||
|
||||
Using B<--env> GNU B<parallel> can transfer an environment variable to the
|
||||
remote system.
|
||||
B<env_parallel> is a shell function that transfers all aliases,
|
||||
functions, variables, and arrays. You active it by running:
|
||||
|
||||
source `which env_parallel.bash`
|
||||
|
||||
Replace B<bash> with the shell you use.
|
||||
|
||||
Now you can use B<env_parallel> instead of B<parallel> and still have
|
||||
your environment:
|
||||
|
||||
alias myecho=echo
|
||||
myvar="Joe's var is"
|
||||
env_parallel -S $SERVER1 'myecho $myvar' ::: green
|
||||
|
||||
Output:
|
||||
|
||||
Joe's var is green
|
||||
|
||||
The disadvantage is that if your environment is huge B<env_parallel>
|
||||
will fail.
|
||||
|
||||
When B<env_parallel> fails, you can still use B<--env> to tell GNU
|
||||
B<parallel> to transfer an environment variable to the remote system.
