awk: non-terminated string - awk

Question

I'm trying to run the command below, and its giving me the error. Thoughts on how to fix? I would rather have this be a one line command than a script.
grep "id\": \"http://room.event.assist.com/event/room/event/" failed_events.txt |
head -n1217 |
awk -F/ ' { print $7 } ' |
awk -F\" ' { print "url \= \"http\:\/\/room\.event\.assist\.com\/event\/room\/event\/'{ print $1 }'\?schema\=1\.3\.0\&form\=json\&pretty\=true\&token\=582EVTY78-03iBkTAf0JAhwOBx\&account\=room_event\"" } '
awk: non-terminated string url = "ht... at source line 1
context is
>>> <<<
awk: giving up
source line number 2
The line below exports out a single column of ID's:
grep "id\": \"http://room.event.assist.com/event/room/event/" failed_events.txt |
head -n1217 |
awk -F/ ' { print $7 } '
156512145
898545774
454658748
898432413
I'm looking to get the ID's above into a string like so:
" url = "string...'ID'string"

Answer 1

take a look what you have in last awk :
awk -F\"
' #single start here
{ print " #double starts for print, no ends
url \= \"http\:\/\/room\.event\.assist\.com\/event\/room\/event\/
' #single ends here???
{ print $1 }'..... #single again??? ...
(rest codes)
and you want to print exact {print } out? i don't think so. why you were nesting print ?

Most of the elements of your pipe can be expressed right inside awk.
I can't tell exactly what you want to do with the last awk script, but here are some points:
Your "grep" is really just looking for a string of text, not a
regexp.
You can save time and simplify things if you use awk's
index() function instead of a RE. Output formats are almost always
best handled using printf().
Since you haven't provided your input data, I can't test this code, so you'll need to adapt it if it doesn't work. But here goes:
awk -F/ '
BEGIN {
string="id\": \"http://room.event.assist.com/event/room/event/";
fmt="url = http://example.com/event/room/event/%s?schema=whatever\n";
}
count == 1217 { nextfile; }
index($0, string) {
split($7, a, "\"");
printf(fmt, a[0]);
count++;
}' failed_events.txt
If you like, you can use awk's -v option to pass in the string variable from a shell script calling this awk script. Or if this is a stand-alone awk script (using #! shebang), you could refer to command line options with ARGV.
