Question

如果我有

这样的文字

/mnt/data/web/web content/page 1/home page.txt

我使用以下命令获取我的文本，然后将其传送到另一个命令。

cat somefile.txt | awk '{$1=$2=$3=$4=$5=$6=$7=$8=$9=$10=""; print $0}'

我需要将上面的命令传递给另一个命令以添加反斜杠

如何在每个空格之前添加反斜杠，以便我得到正确的* nix路径

即

/mnt/data/web/web\ content/page\ 1/home\ page.txt

理论上文本可以无限长，但我总是需要在每个空格之前使用反斜杠。最终脚本将用于freebsd＆amp;的Linux

谢谢！

Answer 1

此awk应该：

awk '{gsub(/ /,"\\ ")}8' file
/mnt/data/web/web\ content/page\ 1/home\ page.txt

Answer 2

对你有用吗？

echo "/mnt/data/web/web content/page 1/home page.txt" > input.txt

然后：

sed 's/ \+/\\ /g' input.txt > output.txt

然后：

cat output.txt
/mnt/data/web/web\ content/page\ 1/home\ page.txt

如果您想为所有空间执行此操作，可以尝试awk

awk：

awk -F" " '{ print $1"\\ " $2"\\ " $3"\\ " $4}' input.txt > output.txt

Answer 3

这可能适合你（GNU sed）：

sed 's/\s/\\&/g' file

Answer 4

您需要引用整个路径：

# Create file
echo Hi > "a file  with   spaces"

# Try to cat it
n="a file  with   spaces"
cat $n
cat: a: No such file or directory
cat: file: No such file or directory
cat: with: No such file or directory
cat: spaces: No such file or directory


# With quotes this time :-)
cat "$n"
Hi

# Wrap file path with "" so it can be treated as $1
# Wrap command with "" if spaces are present to treat as $2
# Wraping time only nessisay for pros ;-) $3
# Example synax;
# format_space_do_time "/dir with/sp ac e s" "Comand With options" "TimeToSleep"
# Set $1, $2 and $3 variable names such that they can be hard-coded for debugging
File_Path="$1"
Commands="$2"
Timed_Sleep="$3"
format_space_do_time (){
# Check if services or command is already in proggress
while true
do
    if ps ax | grep -v grep | grep "$Commands" > /dev/null
    then
    # Waite $Time_Sleep for $Commands to finish
    sleep $Time_Sleep;
    else
    # $Commands not detected. Start'em now
    for i in "$File_Path/"*
    do
        # Magic time, lets deal with spaces in $i and save it to $entry
        # Option 1 replaces " " with "$'\0'" which is bashs way of dealing with spaces
        entry1=$(echo "$i" | sed 's/ /$\'\\\0\'/g')
        # Option 2 can be used to replace " " with "\ " of cource without the quotes around them :-)
        entry2=$(echo "$i" | sed 's/ /\\\ /g')
        # Clear previous outputs
        clear
        # run $Commands against $entry1
        # Change 1 to 2 for the other option
        ${Commands} "${entry1}" > /dev/null
    done
    fi
done
}

中添加了上述scirpt

他们有一些工作正常，直到我不得不处理Gatesbox用户的硬盘驱动器。我个人使用这个脚本通过命令行播放音乐和电影。例如，我将上面保存为omx_play_lister.sh然后保存chmod +x omx_play_lister并运行;

./omx_play_lister "/media/mount/cWin/Music by artist/artist name and album folder" "omxplayer -ohdmi --vol=-2500" "5"

哪位乐意接受文件路径; /media/mount/cWin/Music by artist/artist name and album folder并转换为/media/mount/cWin/Music\ by\ artist/artist\ name\ and\ album\ folder或在omxplayer和ls以及许多其他不太喜欢＆＃34;＆＃34;传递文件路径时的东西。在接近结尾的范围内使用sed命令的好处是，即使文件本身包含空格，在传递给$Commands之前也会格式化这些空格。小"${entry}"和"$File_Path/"*，其中最棘手的格式化排序，但它适用于我所需要的东西以及可能有一些moddification也适用于您的用法。

快乐的黑客攻击和修改。

bash在每个空格之前添加反斜杠？
