GNU parallel not working at all -

-

i have been trying use gnu parallel time, have never been able function @ all!

for example, running (in non-empty directory!):

ls | parallel echo            # outputs single new line ls | parallel echo echo echo  # outputs 3 new lines. ls | parallel echo {}         # /bin/bash: {}: command not found ls | parallel echo '{}'       # /bin/bash: {}: command not found ls | parallel 'echo {}'       # outputs: {} ls | parallel -imm 'echo mm'  # outputs: mm

it seems executing each argument command, makes no sense.

i have tried bash, zsh, tcsh, csh, , sh, no avail.

as complete writing question, ran parallel --version report version, find:

warning: using --tollef. if things acting weird use --gnu.

it not clear me why flag set default. needless say, using --gnu worked!

thought post save hours of frustration , confusion.

edit: fix permanently (in ubuntu @ least), delete --tollef flag in /etc/parallel/config

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
