Ok,
Trying to decipher a Korn Shell script written by someone else. What
exactly do these two lines do?
cp ${FILE:-null} ${LOG_WEEK_OLD}
rm -f ${FILE:-null}
I think the first line copies "/dev/null" to the log file, overwritting the
log file with an empty log file. (i.e. this truncates the file), but if that
is the case what is with the second line? How and why would you want to
delete a null?
Thanks,
Andy
