Delete empty entries from timewarrior

timew-delete-empty.sh

# Delete timewarrior entries that are less than a minute long. 
# Beware - in this version, grep doesn't check the duration field here, so if you have a task that starts at 0:00, that'll be delete too!

for i in $(timew summary :ids | grep '0:00:..' | awk '{print $1}' | tr '\n' ' '); do timew delete $i; donefor i in $(timew summary :ids | grep 0:00:00 | awk '{print $1}' | tr '\n' ' '); do timew delete $i; done

# This one extracts the id and duration fields and then does the bit, so it's safer, but it's more complex.
# The last grep decides what must be deleted, so one can change the regex there as one wishes.
