Continue output on same line
提问by Johan
Want to do a fancy effect by printing [OK] at the end of the last line when a task is finished.
想通过在任务完成时在最后一行的末尾打印[OK]来做一个花哨的效果。
Got this:
明白啦：
echo "echo -n "printf "%s" "##代码##: Starting backup process in '$backupdir'... "
sleep 3
printf '[OK]\n'
: Starting backup process in '$backupdir'... "
: Starting backup process in '$backupdir'... "
sleep 3
echo '[OK]'
I tried different things at the end of the first echo, at the beginning of the second like \r, \c, \, Googled it... No good.
我在第一个回声结束时尝试了不同的事情，在第二个回声开始时尝试了不同的东西，例如\r, \c, \, 谷歌搜索...不好。
I want it to output this:
我希望它输出这个：
./backup.sh: Starting backup process in '/backup'...
./backup.sh: Starting backup process in '/backup'...
... And 3 sec later, add the [OK]:
... 3 秒后，添加[OK]：
./backup.sh: Starting backup process in '/backup'... [OK]
./backup.sh: Starting backup process in '/backup'... [OK]
Thanks,
谢谢，
