if [ -z $2 ];then
echo "lack function parameter "
return -1
fi
mv -f $1 $2
return 0
}
function change()
{
ofileName= # old file name
nfileName= #new file name
ls -l > a.txt
index=0
while read line
do
index=`expr ${index} + 1`
if [ ${index} -eq 1 ] ; then
continue; # ignore the first line of 'ls -l'
fi
a=($line)
#echo ${a[8]} the 9th element of array is file name
#echo ${a[3]} # the 3rd element of array is owner name
ofileName=${a[8]}
pos=`expr index ${ofileName} "."` # pos = the . position in file name
if [ ${pos} -eq 0 ] ; then # if no . in file name then nfileName=oldName+[+owner+]
nfileName="${ofileName}[${a[3]}]"
else
owner="[${a[3]}]."
nfileName="${a[8]/./${owner}} " # substitute the . character to the "[owner]."
fi
echo "nfilename=${nfileName}"
changename ${ofileName} ${nfileName} #call function changename to change file name to new file name
done<a.txt
}

change
ls -l
echo "changed successfully"

Answer 1

vim是字符编辑器（跟图形界面下gedit功能类似，只是在字符界面下，熟悉后功能更强大），不是编译器，这段代码需要添加可执行权限后双击，选择运行或打开终端运行该文件。

你要先编译该段代码,可以用gcc编译,然后运行便可
