Like zaxxon, I also like this approach; clever use of FS and NF.
However, it does have a bug. If the value of $NF is the number zero, !$NF will be true (since $NF is evaluated numerically, instead of as a string), which would be incorrect. The solution would be to use length($NF) or concatenate a null string to force conversion to a string type, $NF"".
Example:
Code:
$ cat data
"ABCD RENT-A-
CAR XYZ LTD","00N0H","Enterprise Lake","0
View Way"
$ # Incorrect
awk -F"\"" '!$NF{print;next}{printf("%s ", $0)}' data
"ABCD RENT-A- CAR XYZ LTD","00N0H","Enterprise Lake","0
View Way"
$ # Correct
$ awk -F"\"" '!($NF""){print;next}{printf("%s ", $0)}' data
"ABCD RENT-A- CAR XYZ LTD","00N0H","Enterprise Lake","0 View Way"
$# Correct
$ awk -F"\"" '!length($NF){print;next}{printf("%s ", $0)}' data
"ABCD RENT-A- CAR XYZ LTD","00N0H","Enterprise Lake","0 View Way"
a golfed version of franklin52's approach:
Code:
$ awk -F'"' '$NF""{printf("%s ", $0);next}1' data
"ABCD RENT-A- CAR XYZ LTD","00N0H","Enterprise Lake","0 View Way"
Even so, I'm not sure this approach meets the original poster's needs. If a line with an odd number of quotes ends on a quote, it will not have the trailing newline replaced with a space.
I'm not very familiar with the ssh command. When I tried to set a variable and then echo its value on a remote machine via ssh, I found a problem. For example,
$ ITSME=itsme
$ ssh xxx.xxxx.xxx.xxx "ITSME=itsyou; echo $ITSME"
itsme
$ ssh xxx.xxxx.xxx.xxx 'ITSME=itsyou; echo $ITSME'
