How does one get an asterisk '*' in a csh variable ? I've been trying for a long time to figure this one out but can't achieve it ? What about if you're reading chars in from a file into csh variables and one of them is a '*' it doesn't appear into the csh variable at all ! maf. -------------------------------------------------------------------------------- Martin Foord ACSnet,Ean,CSnet: martin@mqcomp.mq.oz Computing Discipline Arpa: martin%mqcomp.mq.oz@UUNET.UU.NET Macquarie University 2109 Janet: martin%mqcomp.mq.oz@UK.AC.UKC Australia UUCP: {uunet,mcvax}!munnari!mqcomp.mq.oz!martin D

To verify this, try echo "$x" after each one. _Don't_ try echo $x as filename generation is done after variable substitution. (Tested in DYNIX 4.2BSD, SunOS3.2, System V.3/386.)

This prints the values of all shell variables without doing any kinds of substitution. -- David Elliott dce@mips.com or {ames,prls,pyramid,decwrl}!mips!dce "Did you see his eyes?

Because it has to be escaped.
% set x=\*
% echo "$x"
