Edit number of lines in a file to single line
Greetings,
I have a file: hostnames.txt which has -
# cat hostnames.txt
machine1
machine2

I need the output to be saved to a variable as:
HOSTNAMELIST=machine1,machine2

Please advise.

Thanks,
Chiru

Just a fast one
Code:
awk '{a=a $0 ","}END{print "HOSTNAMELIST=" a }' hostnames.txt

Thanks Danmero, that works 99% perfect. Only one thing is that - can I not have the ',' at the end?

Thanks again,
Chiru

What about your contribution Smilie ?
This is a "fast" line, not clean but will do your job.
Code:
awk '{a=a $0 ","}END{print "HOSTNAMELIST=" a }' hostnames.txt | sed 's/.$//'
