In the shell scripts that are used to configure htdig and some associated
software like xpdf-3.00 are many exit statements like the list
{ (exit 1); exit 1; }
What function does the exit in a sub-shell serve? It would have the effect of
setting the status value to 1 but the exit statement in the current shell after
it would exit with its stated value regardless.
These exit statements are often part of an enclosing list as in
{ echo "$as_me: error: cannot find myself; rerun with an absolute path" >&2
{ (exit 1); exit 1; }; }
or an enclosing list which also encloses another list as in
{ { echo "$as_me:$LINENO: error: run \`make distclean' and/or \`rm $cache_file
' and start over" >&5
echo "$as_me: error: run \`make distclean' and/or \`rm $cache_file' and start
ov
er" >&2;}
{ (exit 1); exit 1; }; }
What is the purpose of the lists encased in braces? Wouldn't the commands in
the same sequence have the same effects without the defined lists?
TIA.
