[SOLVED] Separate values with commas on one line from a variable BASH

Issue

I have a bash script which stores some values in a variable and outputs each value on a separate line like this:

2288
87
183
30
16

I need the values to be in this format on one line so I can export to CSV:

2288, 87, 183, 30, 16

I have looked at some examples online of using sed or awk but couldn't find an example similar to mine.

Any help would be appreciated.

Solution

paste is your friend:

$ paste -s -d',' file
2288,87,183,30,16

You can also use tr or awk, but you will get a trailing comma:

$ awk '{printf $0","}' file
2288,87,183,30,16,

$ tr -s '\n' ',' <file
2288,87,183,30,16,

Update

Its not a file its a variable I have it doesn't appear to work in the same way?

Kind of:

$ myvar="2288
87
183
30"
$ echo "$myvar" | paste -s -d','
2288,87,183,30
$ echo "$myvar" | tr -s '\n' ', ' 
2288,87,183,30,
$ echo "$myvar" | awk '{printf $0","}'
2288,87,183,30,
