我不知道回答這類問題是否有好處，因爲它是作業......但我看到其他問題被標記爲家庭作業已回答，所以我們走了。

#!/bin/bash 
RYD=/share 
FILESPEC=*.sh 
DIRPERM=700 
FILEPERM=750 
OWNER=user:group 
CH_FSPEC=0 
if [ -d $RYD ]; then # If $RYD is a directory 
    find $RYD -type d | xargs chmod $DIRPERM # Look for all subdirectories and chmod them with $DIRPERM 
    if [ $CH_FSPEC -gt 0 ]; then # if $CH_FSPEC > 0 
    find $RYD -type f | xargs chmod $FILEPERM # find all files inside $RYD and chmod them with $FILEPERM 
    else # if $CH_FSPEC <= 0 
    find $RYD -type f | grep -v "$FILESPEC" | xargs chmod $FILEPERM # find all files inside $RYD, ommit *.sh files and chmod them with $FILEPERM 
    fi 
    chown -R $OWNER $RYD # chown $RYD with $OWNER 
    for SCRIPT in $RYD/$FILESPEC; do # loop *.sh files inside $RYD 
    if [ -x $SCRIPT ]; then # if they have exec perm 
     echo "Executing : $SCRIPT" # run it 
     . $SCRIPT 
    fi 
    done 
else # if $RYD does not exist or isnt a directory 
    echo "ERROR! The directory doesn't exist." 
    exit 1 
fi 
exit 0 

請，對不起，如果我不應該回答這個問題......如果這是錯的，請刪除它，並提醒我不要再這樣做。
