True. Csh's insistance on ALWAYS tackling $s within "..." can be
counter-acted by using a nifty aux definion:
set dollar=$
The entire thing then becomes, without flipping between quoting styles:
alias Q4 "sed -e 's/\$dollar//g'"
I'd consider this "pretty agreeable". The entire(?) aux list
set dollar=$ sq=\' dq=\" bs=\\
can drag you through a other problematic contexts. Because,
csh won't let you put a ' within '...' or a " within "...",
either :-(
Note that any $ followed by white space or nothing at all is not
subject to variable expansion. IMHO, the easiest solution for
the task is
alias Q5 tr -d $
Look Ma, neither freaking quotes nor backslashes at all!
