答案1
$ lsblk -ape7 -o+LABEL,FSSIZE,FSUSE%为您提供实际磁盘和分区的简短列表，包括大小和已使用百分比。
列表中的大部分是已安装的“snap”软件包...（包括旧的和已禁用的）
为了在某种程度上清理 snap 包...将此文本放在文件中...
B="$(输入转速)"
R="$(输入 sgr 0)"
echo -e "\n${B}Snap 更新？当前内容/列表：${R}"
如果 [ !-z "$( which snap)" ] ;那么
快照列表--全部
echo -e“\n...可用更新列表？”
快照刷新--列表|sed-re's/\x1B.*\[K//'
echo -e“\nsnap refresh # 正在执行实际更新。”
sudo snap 刷新
echo -e“\nsnap 删除‘已禁用’项目上的#……”
# https://askubuntu.com/a/1040131/289138
快照列表--all | awk'/disabled/{print $1, $3}'|
读取 snapname 修订版本时；执行
sudo snap 删除 "$snapname" --revision="$revision"
完毕
别的
echo -e “‘snap’不存在。”
菲
... 然后做$ source file
