我正在尝试将Linux脚本适合我的WD世界版驱动器。

该脚本是为Bash(Debian)编写的,但我的WD仅运行busybox(带有ash)。尽管如此,仅通过使用Google我就获得了大多数功能。我只有一个运算符尚未找到对应的==运算符

如何将=〜运算符的功能从旧脚本移植到ash?

脚本:

#! /bin/bash
# posttorrent.sh by Killemov
{
  # Log file, file where we tell what events have been processed.
  LOG_FILE=/var/log/posttorrent.log
  # Username for transmission remote.
  TR_USERNAME="username"
  # Password for transmission remote.
  TR_PASSWORD="password"
  # Get current time.
  NOW=$(date +%Y-%m-%d\ %H:%M:%S)
  # Source directory, should not be changed.
  SRC_DIR="${TR_TORRENT_DIR}/${TR_TORRENT_NAME}"
  # Directory to store the un-compressed files in..
  DEST_DIR="${TR_TORRENT_DIR}/${TR_TORRENT_NAME}/"
  # This parameter string could be passed from Transmission in the future.
  TR_TORRENT_PARAMETER="EXTRACT SLEEP1h"

echo "text"
  if [ -e "$SRC_DIR/keep" ]; then
    TR_TORRENT_PARAMETER="$TR_TORRENT_PARAMETER KEEP"
  fi

  if [ -e "$SRC_DIR/exit" ]; then
    TR_TORRENT_PARAMETER="EXIT"
  fi

  # Actual processing starts here.
  if [[ "$TR_TORRENT_PARAMETER" =~ "EXIT" ]]; then
    echo $NOW "Exiting $TR_TORRENT_NAME" >> $LOG_FILE
    exit 0
  fi
echo "text2"
  if [[ "$TR_TORRENT_PARAMETER" =~ "EXTRACT" ]]; then
    cd $TR_TORRENT_DIR
    if [ -d "$SRC_DIR" ]; then
      IFS=$'\n'
      unset RAR_FILES i
      for RAR_FILE in $( find "$SRC_DIR" -iname "*.rar" ); do
        if [[ $RAR_FILE =~ .*part.*.rar ]]; then
          if [[ $RAR_FILE =~ .*part0*1.rar ]]; then
            RAR_FILES[i++]=$RAR_FILE
          fi
        else
          RAR_FILES[i++]=$RAR_FILE
        fi
      done
      unset IFS

      if [ ${#RAR_FILES} -gt 0 ]; then
        for RAR_FILE in "$(eval \$$RAR_FILES[@])"; do
          unrar x -inul "$RAR_FILE" "$DEST_DIR"
          if [ $? -gt 0 ]; then
            echo $NOW "Error unrarring $TR_TORRENT_NAME" >> $LOG_FILE
            transmission-remote -n $TR_USERNAME:$TR_PASSWORD -t$TR_TORRENT_ID --verify --start
            exit 0
          fi
        done
        if [[ ! "$TR_TORRENT_PARAMETER" =~ "KEEP" ]]; then
          SLEEP=$(expr match "$TR_TORRENT_PARAMETER" '.*SLEEP\([0-9a-zA-Z]*\)')
          if [ ${#SLEEP} -gt 0 ]; then
            sleep $SLEEP
          fi
          transmission-remote -n $TR_USERNAME:$TR_PASSWORD -t$TR_TORRENT_ID --remove-and-delete
        fi
        echo $NOW "Unrarred $TR_TORRENT_NAME" >> $LOG_FILE
      fi
    fi
  fi
} &


(我在使用间接引用时遇到了麻烦,希望我可以正确地解决该问题)

最佳答案

对于$VARIABLE =~ PATERN,您应该可以使用:

echo "$VARIABLE" | grep -E PATTERN


但是我认为您也会对算术表达式i++遇到一些麻烦-如果实现了,则仍然需要使用i=$(($i + 1))语法,如果没有实现,则需要使用i=$(expr $i + 1)语法。

我想您是因为IFS = $'\ n'是在换行符上拆分查找的原因,但是最好将查找结果发布到临时文件中,然后执行while read line; do ... done <$tmpfile

另外,我不确定busybox ash的所有版本是否都支持阵列,因此您在那里也可能有问题。
