What does tr -s '\n' ',' < testfile give ?

Seems to be doing what I want, but it also appends root prompt ?

root@sun6 # tr -s '\n' ',' < testfile
string1,string2,string3,string4,root@sun6 #

it is because

"tr -s '\n' ',' < testfile" removes the newline on which "sed" is searching
ie "Output line from tr doesn't have newline character at the end"

So we can go for xargs as follows which may help you

xargs < testfile | sed -e "s/,$//g"

xargs < testfile | sed -e "s/,$//g" gives correct result but have unwanted spaces in the output:

root@sun6 # xargs < testfile | sed -e "s/,$//g"
string1,string2 ,string3 ,string4
# 12

Thanks all for your help, used

xargs < testfile | sed 's/ //g'

and it works 100%.
