  • Merge Time and Eta

Show current merge time and eta

genlop -c | grep -E 'current merge time|ETA'

Another way to show current merge time and eta

genlop -c | awk -F': ' '
/current merge time/ { printf "⏱  Merge time: %s\n", $2 }
/ETA/                { printf "⌛ ETA:        %s\n", $2 }
'

Minimalist one-liner (pure POSIX grep)

genlop -c | grep -e 'current merge time' -e '^ *ETA'
