I need help from SED gurus

[fangis]

Hello friends,

I have searched the documentation but can't seem to make this work.
What I want to do is the following:
get the user to type a word
convert the spaces in this word to commas, and save it into a new variable

but when i use:
read var
i dont know how to make sed modify this var. Is it possible?
Thanks for the help, i appreciate it.

var=`echo $var | sed 's: :,:g'`

Does that do what you need?

hi, thanks for the help.
No luck yet, i made the following script:

#!/bin/sh
echo "please type the string:"
read var
var=echo $var | sed 's::,:g'
echo "your converted string: $var"


this way gave no results, i typed, this is a test, gives:
line 5:this: not found
your converted string: this is a test

I also tried to use commas around echo, but it seems to not work
can you try the script?
thank you!

Hi fangis
You left out the back ticks usally found on the ~ key.
Try changing this:

Code: [Select]

var=echo $var | sed 's::,:g'To this:

Code: [Select]

var=`echo $var | sed 's: :,:g'`

Or using tr:
var=`echo $VAR | tr " " ","`
or
var=$(echo $var | tr " " ",")
