How to delete branches older than 1 month that was merged to master programmatically in git?

Question

是否有一个命令能够以编程方式删除超过 1 个月的分支并一次性合并到 master 分支？

Answer 1

Building on top of the answer shared by @LazarNikolic ( Delete all branches that are more than X days/weeks old ):

for k in $(git branch --merged master | sed /\*/d); do 
  if [ -n "$(git log -1 --before='1 month ago' -s $k)" ]; then
    git branch -D $k
  fi
done

Some background:

• git granch --merged master to only list branches that have been merged to master .
• git log --before to inspect log entries that are more than 1 month old. If any entries exist, for any merged branch, delete that branch.

Answer 2

In my case I'm using git version 2.25.1. The answer above did not work for me but this does.

# Purge branches older than 1 month
for k in $(git branch | sed /\*/d)
do 
    log "Found branch $k"
    if [ -n "$(git log -1 --before='1 month ago' --grep='$k')" ]
    then
        git push -d origin $k &> /dev/null
        git branch -d $k &> /dev/null
        log "Purged branch $k"
    fi
done
