From: Steven Baltakatei Sandoval Date: Mon, 29 Jun 2020 11:43:35 +0000 (+0000) Subject: feat(bkgpslog):Enable hour TTL, cleanup functions X-Git-Url: https://zdv2.bktei.com/gitweb/EVA-2020-02.git/commitdiff_plain/c2aaff78bd38230ab42fcb7509276dff7d0d9b58?hp=d4ead4d172224fbaf4d3da23ce6eef13265f5dc2 feat(bkgpslog):Enable hour TTL, cleanup functions Enable a new feature that breaks the while loop at the top of the next hour. Include commented-out code to break while loop at the top of the next day. Set buffer round time to 60 seconds (nominal time between writing of buffer data to a new file on disk). --- diff --git a/exec/bkgpslog b/exec/bkgpslog index aed0e90..999775e 100755 --- a/exec/bkgpslog +++ b/exec/bkgpslog @@ -182,31 +182,58 @@ processArguments() { shift done } # Argument Processing -timeUntilMidnight(){ - # Desc: Report seconds until midnight - # Output: stdout: integer seconds until midnight +timeUntilNextDay(){ + # Desc: Report seconds until next day. + # Output: stdout: integer seconds until next day # Output: exit code 0 if stdout > 0; 1 if stdout = 0; 2 if stdout < 0 - # Usage: timeUntilMidnight - # Usage: if !
