我正在尝试将适用于Linux的脚本放到我的WD世界版驱动器上。
脚本是为Bash(debian)编写的,但我的WD只运行busybox(带灰)。尽管如此,我还是通过使用Google获得了大部分功能。只有一个运算符我找不到对应的=〜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

答案 0 :(得分:0)
对于$VARIABLE =~ PATERN
,您应该可以使用:
echo "$VARIABLE" | grep -E PATTERN
但是我认为你的算术表达式i++
也会遇到一些麻烦 - 如果它已经实现了,那么你仍然需要使用i=$(($i + 1))
语法,如果它没有实现,那么i=$(expr $i + 1)
语法。
我认为你是IFS = $'\ n'的理由是在新行上拆分查找,但你可能最好将find发布到一个临时文件中,然后执行{{1} },
此外,我不确定所有版本的busybox ash是否支持数组,因此您可能也遇到问题。
