Answer 1

If you are talking about sed , this works:

sed -e "s/ /,/g" < a.txt

In vim , use same regex to replace:

s/ /,/g

Answer 2

Inside vim , you want to type when in normal (command) mode:

:%s/ /,/g

On the terminal prompt, you can use sed to perform this on a file:

sed -i 's/\ /,/g' input_file

Note: the -i option to sed means "in-place edit", as in that it will modify the input file.

Answer 3

我知道这不完全是您要的内容，但是，用换行符替换逗号，效果很好：

tr , '\n' < file

Answer 4

尝试以下命令，它应该为您解决。

sed "s/\s/,/g" orignalFive.csv > editedFinal.csv

Answer 5

If you want the output on terminal then,

$sed 's/ /,/g' filename.txt

But if you want to edit the file itself ie if you want to replace space with the comma in the file then,

$sed -i 's/ /,/g' filename.txt

Answer 6

I just confirmed that:

cat file.txt | sed "s/\s/,/g"

successfully replaces spaces with commas in Cygwin terminals (mintty 2.9.0). None of the other samples worked for me.

Answer 7

IF your data includes an arbitrary sequence of blank characters (tab, space), and you want to replace each sequence with one comma, use the following:

sed 's/[\t ]+/,/g' input_file

or

sed -r 's/[[:blank:]]+/,/g' input_file

If you want to replace sequence of space characters, which includes other characters such as carriage return and backspace, etc, then use the following:

sed -r 's/[[:space:]]+/,/g' input_file

Answer 8

On Linux use below to test (it would replace the whitespaces with comma)

 sed 's/\s/,/g' /tmp/test.txt | head

later you can take the output into the file using below command:

sed 's/\s/,/g' /tmp/test.txt > /tmp/test_final.txt

PS: test is the file which you want to use
