Cut Reorder and Output to Text

Question

I'm currently learning CentOS and need some assistance if possible. I have a file UserNameList.lst, which is used to generate user accounts. The content of the file is below

Josh, Adams, [email protected]
Henry, Ford, [email protected]

I need to output a txt file which looks like this. (basically combining column 2 and 1 to make a single column)

Adams Josh
Ford Henry

I tried using the command

cut -d "," -f 1 >> Last.txt
cut -d "," -f 2 >> First.txt
paste First.txt Last.txt >> full

which outputs

Adams    Josh
Ford     Henry

Is there a simpler way to do this?

Answer 1

This is best suited for awk

$ cat ip.txt 
Josh, Adams, [email protected]
Henry, Ford, [email protected]

$ awk -F"[ ,]+" '{print $2, $1}' ip.txt 
Adams Josh
Ford Henry

• -F"[ ,]+" field separator is one or more of space and , characters
• Then simply print second and first columns
