在Unix中比较和修剪名称

Question

我对这部分脚本有疑问。我需要比较两个变量。此外，我已经设置了一些功能，用于修剪我需要比较的名称。

任何人都可以帮我找到错误吗？

锁定文件检查

checkLock () 
{
 DATE_LCK=`date '+%Y%m%d'`
 FILE_LOCK=$DATE_LCK"_"LCK"_"$ENTITY".lock"
 cd $LOCK
 if [ -f "$FILE_LOCK" ]
  then
    for i in `ls -rt *.lock `
    do
      INPUTFILE=$i
      LOCK_ENTITY_NAME= `echo "$INPUTFILE"` 
      #LOCK_ENTITY_NAME= `echo "${INPUTFILE}" | head -n 1 | cut -d "_" -f3 | cut -d "." -f1`
      if [ $ENTITY == $LOCK_ENTITY_NAME ]
        then
          echo `date '+%a %b %d %H:%M:%S :'` "File Lock exist for the entity selected process interrupted" >> $LOG_FILE
          exit 1
        else   
        echo `date '+%a %b %d %H:%M:%S :'` "Create File lock for the Entity selected" >> $LOG_FILE
        touch $LOCK/$FILE_LOCK
      fi 
     done
  else
      echo `date '+%a %b %d %H:%M:%S :'` "Create File lock for the process" >> $LOG_FILE
      touch $LOCK/$FILE_LOCK
 fi 
}

使用checkLock () { # Consider using lowercase vars DATE_LCK=$(date '+%Y%m%d') FILE_LOCK="${DATE_LCK}_LCK_${ENTITY}.lock" # Is ${LOCK} set to some value? cd ${LOCK} if [ -f "${FILE_LOCK}" ]; then # you do not need the ls for LOCK_ENTITY_NAME in *.lock; do if [ "${ENTITY}" = "${LOCK_ENTITY_NAME}" ]; then echo "$(date '+%a %b %d %H:%M:%S') : File Lock exist for the entity selected process interrupted" >> ${LOG_FILE} exit 1 else echo "$(date '+%a %b %d %H:%M:%S) : Create File lock for the Entity selected" >> ${LOG_FILE} # You already did "cd ${LOCK}", the touch doesn't need the path again, # you are still in the [ -f "${FILE_LOCK}" ] loop, the lockfile exists (you are only changing the modification date) touch ${FILE_LOCK} fi done else echo "$(date '+%a %b %d %H:%M:%S) : Create File lock for the process" >> ${LOG_FILE} touch ${FILE_LOCK} fi } （一个等号）测试变量。 一些更改：

if [ -f "${ENTITY}" ]

使用此代码，您可以看到更多内容以进行改进。现在您正在测试子目录中的所有文件，并且您正尝试触摸每个文件* .lock文件的$ {FILE_LOCK}。
你可以不使用function mylog { echo "$(date '+%a %b %d %H:%M:%S') : $*" >> ${LOG_FILE} } # and call the function with mylog "File Lock exist for the entity selected process interrupted" 的for循环。 也许你想要一个像

这样的记录功能

val results = task.getAssignedFiles map {
  file: File => Future[Result] {
    <heavy computation>
  }
}
