私は単純なファイル処理スクリプトを書いていますが、最後を除いてうまくいきます。私が言うことは、do you want to perform another action答えが「はい」であれば、yesスクリプトを再起動したいということです。一種のループが必要であることを知っていますか？これが私が持っているものです：
#/bin/bash
echo "Select an option from copy , remove , rename , linking"
#read in user input into the action variable
read action
# if action is copy then continue proceed with the following
if [ $action = "copy" ]
then
echo "Please enter the filename you wish to copy"
read filename
# check if filename exists, if it doesn't then exit program
if [ ! -e $filename ]
then
echo "$filename does not exist"
exit 1
fi
echo "Please enter the new filename"
read filenamenew
cp $filename $filenamenew
echo "$filename has been copied to $filenamenew"
# if action is remove then continue proceed with the following
elif [ $action = "remove" ]
then
echo "Please enter the filename you wish to remove"
read filename
# check if filename exists, if it doesn't then exit program
if [ ! -e $filename ]
then
echo "$filename does not exist"
exit 1
fi
rm -rf $filename
echo "$filename has been deleted"
# if action is rename then continue proceed with the following
elif [ $action = "rename" ]
then
echo "Please enter the filename you wish to rename"
read filename
# check if filename exists, if it doesn't then exit program
if [ ! -e $filename ]
then
echo "$filename does not exist"
exit 1
fi
echo "Please enter the new filename"
read filenamenew
mv $filename $filenamenew
echo "$filename has been renamed to $filenamenew"
fi
echo "Do you want to perform another file operation (yes/no) ?"
read answer
if [ $answer = yes ]
then "run script again"
exit 0
elif [ $answer = no ]
then echo "Exiting Program"
exit 0
fi
fi

echo「作業を選択してください...」前
answer=yes
while [ "$answer" = yes ]
do
最後に交換
if [ $answer = yes ]
then "run script again"
exit 0
elif [ $answer = no ]
then echo "Exiting Program"
exit 0
fi
fi
渡す
if [ "$answer" = yes ]
then "run script again"
fi
done
echo "Exiting Program"
exit 0
私がしたことはプログラムをwhile [$condition ] do ; ... done。
answer=yes最初のループの条件がOK（）であることを確認してください。
