or SED if you preffer
或 SED 如果您愿意
sed 's/[:blank:]+/,/g' thefile.txt > the_modified_copy.txt
or even tr
甚至 tr
tr -s '\t' < thefile.txt | tr '\t' ' ' > the_modified_copy.txt
or a simplified version of the tr solution sugested by Sam Bisbee
或 Sam Bisbee 建议的 tr 解决方案的简化版本

better trcommand:
更好的tr命令：
tr [:blank:] \t
This will clean up the output of say, unzip -l, for further processing with grep, cut, etc.
这将清除unzip -l的输出，以便使用 grep、cut 等进行进一步处理。
e.g.,
例如，
unzip -l some-jars-and-textfiles.zip | tr [:blank:] \t | cut -f 5 | grep jar

You can also use astyle. I found it quite useful and it has several options too:
您也可以使用astyle. 我发现它非常有用，它也有几个选项：
Tab and Bracket Options:
If no indentation option is set, the default option of 4 spaces will be used. Equivalent to -s4 --indent=spaces=4. If no brackets option is set, the
brackets will not be changed.
--indent=spaces, --indent=spaces=#, -s, -s#
Indent using # spaces per indent. Between 1 to 20. Not specifying # will result in a default of 4 spaces per indent.
--indent=tab, --indent=tab=#, -t, -t#
Indent using tab characters, assuming that each tab is # spaces long. Between 1 and 20. Not specifying # will result in a default assumption of
4 spaces per tab.`

This will replace consecutive spaces with one space (but not tab).
这将用一个空格（但不是制表符）替换连续的空格。
tr -s '[:blank:]'
This will replace consecutive spaces with a tab.
这将用制表符替换连续的空格。
tr -s '[:blank:]' '\t'

Example command for converting each .js file under the current dir to tabs (only leading spaces are converted):
将当前目录下的每个 .js 文件转换为制表符的示例命令（仅转换前导空格）：
find . -name "*.js" -exec bash -c 'unexpand -t 4 --first-only "#!/bin/bash
find . -type f -and -not -path './.git/*' -exec grep -Iq . {} \; -and -print | while read -r file; do {
echo "Converting... "$file"";
data=$(unexpand --first-only -t 4 "$file");
rm "$file";
echo "$data" > "$file";
}; done;

Download and run the following script to recursively convert soft tabs to hard tabs in plain text files.
下载并运行以下脚本，以递归方式将纯文本文件中的软标签转换为硬标签。
Place and execute the script from inside the folder which contains the plain text files.
从包含纯文本文件的文件夹中放置并执行脚本。
[root@sysresccd /run/archiso/img_dev]# sfdisk -l -q -o Device,Start /dev/sda | tr -s '[:space:]' '\t'
Device Start /dev/sda1 2048 /dev/sda2 411648 /dev/sda3 2508800 /dev/sda4 10639360 /dev/sda5 75307008 /dev/sda6 96278528 /dev/sda7 115809778

If you are talking about replacing all consecutive spaces on a line with a tab then tr -s '[:blank:]' '\t'.
如果您正在谈论用制表符替换一行上的所有连续空格，那么tr -s '[:blank:]' '\t'.
T=$(printf "\t")
sed "s/[[:blank:]]\+/$T/g"
If you are talking about replacing all whitespace (e.g. space, tab, newline, etc.) then tr -s '[:space:]'.
如果您正在谈论替换所有空格（例如空格、制表符、换行符等），那么tr -s '[:space:]'.
sed "s/[[:space:]]\+/$T/g"
If you are talking about fixing a tab-damaged file then use expandand unexpandas mentioned in other answers.
如果您正在谈论修复制表符损坏的文件，请使用expand和unexpand如其他答案中所述。
