我试图从文件创建文件路径列表,但我似乎无法绕过文件路径中的空格。
# Show current series list
PS3="Type a number or 'q' to quit: "
# Create a list of files to display
Current_list=`cat Current_series_list.txt`
select fileName in $Current_list; do
if [ -n "$fileName" ]; then
Selected_series=${fileName}
fi
break
done
Current_series列表中的文件路径为:/ Volumes / Lara的Hard Drive / LARA HARD DRIVE / Series / The Big Bang Theory 3 / The.Big.Bang.Theory S03E11.avi
和
/ Volumes / Lara的硬盘/ LARA HARD DRIVE / Series / nakitaS03E11.avi
所以我希望他们两个分别在我的列表中分别为1和2,但我得到以下结果。
1) /Volumes/Lara's 6) Big
2) Hard 7) Bang
3) Drive/LARA 8) Theory
4) HARD 9) 3/The.Big.Bang.Theory
5) DRIVE/Series/The 10) S03E11.avi
Type a number or 'q' to quit:
答案 0 :(得分:0)
你需要稍微欺骗一下:
# Show current series list
PS3="Type a number or 'q' to quit: "
# Create a list of files to display
Current_list=$(tr '\n' ',' < Current_series_list.txt)
IFS=, read -a list <<< "$Current_list"
select fileName in "${list[@]}"; do
if [ -n "$fileName" ]; then
Selected_series="${fileName}"
fi
break
done
echo "you selected $fileName"
执行:
$ ./a
1) /Volumes/Lara's Hard Drive/LARA HARD DRIVE/Series/The Big Bang Theory3/The.Big.Bang.Theory S03E11.avi
2) /Volumes/Lara's Hard Drive/LARA HARD DRIVE/Series/nakitaS03E11.avi
Type a number or 'q' to quit: 2
you selected /Volumes/Lara's Hard Drive/LARA HARD DRIVE/Series/nakitaS03E11.avi
关键是你必须将文件转换为数组。
此部分将其转换为"string one", "string two"
格式:
$ tr '\n' ',' < Current_series_list.txt
/Volumes/Lara's Hard Drive/LARA HARD DRIVE/Series/The Big Bang Theory 3/The.Big.Bang.Theory S03E11.avi,/Volumes/Lara's Hard Drive/LARA HARD DRIVE/Series/nakitaS03E11.avi,
虽然这个基于上一步中设置的逗号分隔符在变量list
中创建一个数组:
IFS=, read -a list <<< "$Current_list"
答案 1 :(得分:0)
您可以尝试将Current_series_list.txt
的每一行分别读入数组元素,然后从展开的数组"${Current_array[@]}"
中选择:
# Show current series list
PS3="Type a number or 'q' to quit: "
# Create an array of files to display
Current_array=()
while read line; do Current_array+=("$line"); done < Current_series_list.txt
select fileName in "${Current_array[@]}"; do
if [ -n "$fileName" ]; then
Selected_series=${fileName}
fi
break
done
