[Wien] WIEN2k Version 19.1

Fri Jun 14 10:06:05 CEST 2019

I did a little checking on the web, and this appears to be a not uncommon
issues, e.g. Google "csh word too long bug". The link at
https://stackoverflow.com/questions/32781476/linux-how-to-solve-word-too-long-in-suse10-os
and some others indirectly provide ways which could be used to determine
what the maximum allowed length is. It would be useful to work out if:

a) There are differences in the allowed length with OS. I would not be
surprised if there are, I expect that the maximum length is a csh/kernel
parameter set when csh is compiled. Since almost everyone will install a
pre-compiled version, they are at the mercy of Ubuntu/Red Hat/Apple etc.

b) The issue is related to other "stuff" embedded in the relevant variable
that is different in Ubuntu. (I am not sure what the "stuff" is, but by
comparing it should be possible to isolate and test this.)

Some other links of perhaps relevance are
https://serverfault.com/questions/163371/linux-command-line-character-limit

https://community.hpe.com/t5/General/Maximum-Length-of-a-UNIX-ksh-csh-Command-Line/td-p/5018128#.XQNQ1Gko96g
, which also mentions the kernel parameter LINE_MAX _SC_LINE_MAX

N.B., I don't think changing from csh to tcsh is the right approach for a
permanent fix. It hides the issue; even tcsh can have the same problem.
That said, tcsh does appear to be considered "better" and is supposed to be
backward compatible. One could always alias csh to tcsh and keep fingers
crossed (a hack, not a solution). If this works then change "csh" to
"w2ksh" and configure this -- if requested by the user.
