POSIX replacement for bash's “export -n” ?
In one of the packages I maintain, building fails when the default shell is
/bin/dash because of an “export -n” command that was not found by checkbashisms
(probably because it was hidden in a Perl script).
I would like to send a patch Upstream, but have not found a drop-in replacement
for this command, apart from someghing ugly like:
BAR=$FOO ; unset FOO ; FOO=$BAR ; unset BAR
to replace ‘export -n FOO’.
Any idea ?
