我想删除起点，如下所示。
文件名 aaa.txt。
./usr/share/vim/vim73/colors/blue.vim
./usr/share/vim/vim73/colors/default.vim
./usr/share/vim/vim73/colors/peachpuff.vim
./usr/share/vim/vim73/colors/shine.vim
./usr/share/vim/vim73/colors/slate.vim
./usr/share/vim/vim73/colors/desert.vim
./usr/share/vim/vim73/colors/README.txt
./usr/share/vim/vim73/colors/torte.vim
到
/usr/share/vim/vim73/colors/blue.vim
/usr/share/vim/vim73/colors/default.vim
/usr/share/vim/vim73/colors/peachpuff.vim
/usr/share/vim/vim73/colors/shine.vim
/usr/share/vim/vim73/colors/slate.vim
/usr/share/vim/vim73/colors/desert.vim
/usr/share/vim/vim73/colors/README.txt
/usr/share/vim/vim73/colors/torte.vim
我应该怎么办？
答案1
与 sed
sed -e 's,^\./,/,' <inputfile >outputfile
（如果后面有“/”，这只会删除“.”，以防提供不正确的数据）。
