sh -f和-d被視爲-e

Question

因此，出於某種原因，在我的下面的函數中，if [-f]和if [-d]位被破壞。不知何故，sh/android同時將-f和-d視爲-e，這導致我的腳本在Android恢復中運行腳本時無法正常工作。我想知道有沒有人對此有所瞭解？我試圖強迫它與& &，但無濟於事。

readLog() { 
    ui_print "Readlog $1" 
    ui_print "AddPath $2" 
    ADDDIR="$2" 
    if [[ $BACKUP == true ]] 
    then 
     echo $BUILD_VERSION > $BACKUP_DIR"rom_version.txt" 
     echo $FLASHABLE_VERSION > $BACKUP_DIR"flashable_version.txt" 
    fi 
    while IFS= read line 
    do 
    MPATH=${ADDDIR}$line 
    ui_print "Line: $line" 
    if [ -d $MPATH && ! -f $MPATH] 
    ui_print "Dir: $MPATH" 
    then 
     if [ -d $line && $BACKUP == true ] 
     then 
      ui_print "Dir $line Exists, Back it up" 
      # Backup the Directories if they exist 
      mkdir -p $BACKUP_DIR$line 
      echo $line >> $BACKUP_LOG 
     fi 
     mkdir -p $line 
     cp_perm 0 0644 ${ADDDIR}$line $line 

    elif [ -f $MPATH && ! -d $MPATH ]

您應該檢查測試（[）命令的語法。

例如

[ -d $line $BACKUP == true ] 

缺少2個表達之間的運算符。它應該像

[ -d "$line" -a "$BACKUP" == true ]
