[Wien] lapw2 crashed error

[Gavin Abo]

If the "Command not found" is not from the sed command itself, it might 
be caused by the arguments to the sed command.  However, it cannot be 
determined what the cause and solution is unless the script and line 
with the sed command is identified.

If you can provide information on the computing system, perhaps someone 
will encounter the same problem or be able to reproduce it.

Linux version (example, Ubuntu 18.04.3):

sed version (example, output of command 'sed --version' [1]):

tcsh version (example, output of command 'dpkg -l tcsh' [2]):

csh version (example, output of command 'dpkg -l csh' [3]):

WIEN2k version (example, output of command 'cat WIEN2k_VERSION' [4]):

Did you just check 'sed' in your user account?  Since you are doing 
parallel, did you also check if sed works when you login to your nodes 
(which appears to be 'ssh localhost' in your case)?  If you use root, 
su, or sudo for running WIEN2k, I suggest use of the user account 
instead and not those unless your experienced with that as those 
administrative environments can sometimes behave differently with 
unexpected consequences [5].
