我正在写一个脚本来修复一个失踪的＆＃39; F＆＃39;邮件日志文件中的字母。邮件日志文件不断更新。我得到了一个文件名，之后我正在做一个sudo su＆＃39;获得超级用户访问权限。在sudo内部，我正在修复一个失踪的＆＃39; F＆＃39;。但是，我无法在sudo块中使用该文件名。请问任何人都可以帮助我如何在sudo中导出这些shell变量？我尝试使用导出，但它无法正常工作。我创建的代码块如下 -

cd /var/spool/mail #mail files reside in mail folder
echo "Entered in mail folder"
filename=`ls -lrt 99999*| sort -k 5 -rn | head -1 | tr -s " " "," | cut -d "," -f "8"` # this will list the file with maximum size`
echo "File with maximum size is $filename"
echo "----------------------------------------------------"
echo "Is it the file expected?(y/n)"
read choice
if test $choice == "n"

echo "Exiting...."
exit;

ls -lrt $filename

echo "First line of the file is as below :"
head -1 $filename

echo "Repeat : $firstline"
echo $firstline | grep ^"rom" >/dev/null
if test $? -eq 0
