"${fname##*[.,~\#]}" = "$fname"是什么意思。

如果fname等于以下情况是否为真：
1) #xx
2) xx~
3) xx.BAK

Hi,

This is a condition that checks if the $fname contains any ".", ",", "~", "\" and "#".

e.g.

if [ "${fname##*[.,~\#]}" = "$fname" ]; then
   echo "$fname doesn't contain .,~\#"
fi

All the 3 situations you listed are false.
