Question

因此，出于某种原因，在我的下面的函数中，if [-f]和if [-d]位被破坏了。不知怎的，sh / android同时将-f和-d视为-e，这导致我的脚本在android恢复中运行脚本时无法正常运行。我想知道是否有人对此有任何见解？我尝试使用＆amp;＆amp;和强制它，但无济于事。

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 ]
    ui_print "File: $MPATH"
    then
        if [ -f $line && $BACKUP == true ]
        then
            ui_print "File $line Exists, Back it up"
            # Backup the files if they exist. Permissions don't matter here.
            cp $line $BACKUP_DIR$line
            echo $line >> $BACKUP_LOG
        fi
        cp_perm 0 0 0755 ${ADDDIR}$line $line

    fi
    done < $1
}

这是完整的脚本：

    then

        RESTORE=true

sort -o $BACKUP_DIR$CP_LOG $CP_LOG
sort -o $BACKUP_DIR$EXEMPT_LOG $EXEMPT_LOG
sort -o $BACKUP_DIR$BACKUP_LOG $BACKUP_LOG

Answer 1

您应该检查测试（[）命令的语法。

例如

[ -d $line $BACKUP == true ]

缺少2个表达式之间的运算符。它应该像

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

sh -f和-d被视为-e
