In the Bourne shell, the sequence of commands
export KILLIT
unset KILLIT
will remove KILLIT from the shell's environment altogether. The closest I
can seem to come in the C shell is
setenv KILLIT ''
which defines KILLIT to be the null string, but does not remove it. Am I
stuck with:
exec sh -c 'export KILLIT;unset KILLIT;exec csh'
???
