answer is trivially obvious, and I'm just
too stressed out and deadlined in to see it.
Here goes:
I'm trying to write a program to manage a
mailing list. The mailing list uses carriage
returns as delimiters, but the user's computer
uses quotes and commas. So I'm trying to change
this:
bogus@xxxxxxxxx
sugob@xxxxxxxxx
gusbog@xxxxxxxxx
gobsu@xxxxxxxxx
gobus@xxxxxxxxx
spambot@xxxxxxxxxxxxx
tobmaps@xxxxxxxxxxxxx
botsmap@xxxxxxxxxxxxx
scamad@xxxxxxxxxx
damcas@xxxxxxxxxx
casmad@xxxxxxxxxx
bogus@xxxxxxxxx
sugob@xxxxxxxxx
gusbog@xxxxxxxxx
gobsu@xxxxxxxxx
gobus@xxxxxxxxx
spambot@xxxxxxxxxxxxx
tobmaps@xxxxxxxxxxxxx
botsmap@xxxxxxxxxxxxx
scamad@xxxxxxxxxx
damcas@xxxxxxxxxx
casmad@xxxxxxxxxx
bogus@xxxxxxxxx
sugob@xxxxxxxxx
gusbog@xxxxxxxxx
gobsu@xxxxxxxxx
gobus@xxxxxxxxx
spambot@xxxxxxxxxxxxx
tobmaps@xxxxxxxxxxxxx
botsmap@xxxxxxxxxxxxx
scamad@xxxxxxxxxx
damcas@xxxxxxxxxx
into this:
"bogus@xxxxxxxxx", "sugob@xxxxxxxxx", "gusbog@xxxxxxxxx", "gobsu@xxxxxxxxx", "gobus@xxxxxxxxx", "spambot@xxxxxxxxxxxxx", "tobmaps@xxxxxxxxxxxxx", "botsmap@xxxxxxxxxxxxx", "scamad@xxxxxxxxxx", "damcas@xxxxxxxxxx", "casmad@xxxxxxxxxx", "bogus@xxxxxxxxx", "sugob@xxxxxxxxx", "gusbog@xxxxxxxxx", "gobsu@xxxxxxxxx", "gobus@xxxxxxxxx", "spambot@xxxxxxxxxxxxx", "tobmaps@xxxxxxxxxxxxx", "botsmap@xxxxxxxxxxxxx", "scamad@xxxxxxxxxx", "damcas@xxxxxxxxxx", "casmad@xxxxxxxxxx", "bogus@xxxxxxxxx", "sugob@xxxxxxxxx", "gusbog@xxxxxxxxx", "gobsu@xxxxxxxxx", "gobus@xxxxxxxxx", "spambot@xxxxxxxxxxxxx", "tobmaps@xxxxxxxxxxxxx", "botsmap@xxxxxxxxxxxxx", "scamad@xxxxxxxxxx", "damcas@xxxxxxxxxx", "casmad@xxxxxxxxxx", "bogus@xxxxxxxxx", "sugob@xxxxxxxxx", "gusbog@xxxxxxxxx", "gobsu@xxxxxxxxx", "gobus@xxxxxxxxx", "spambot@xxxxxxxxxxxxx", "tobmaps@xxxxxxxxxxxxx", "botsmap@xxxxxxxxxxxxx", "scamad@xxxxxxxxxx", "damcas@xxxxxxxxxx", "casmad@xxxxxxxxxx"
the script I'm using looks like this:
#!/bin/sh
sed 'N;s/\n/", "/;P;D;' ~/Desktop/bogus.list >~/Desktop/output.list
and produces this:
bogus@xxxxxxxxx", "sugob@xxxxxxxxx
gobsu@xxxxxxxxx", "gobus@xxxxxxxxx
spambot@xxxxxxxxxxxxx", "tobmaps@xxxxxxxxxxxxx
botsmap@xxxxxxxxxxxxx", "scamad@xxxxxxxxxx
damcas@xxxxxxxxxx", "casmad@xxxxxxxxxx
what exactly am I doing wrong, and how can I fix it?
awk 'NR > 1 { printf "," }
{ printf "\"%s\"", $0 }
END { print "" }
' "$HOME/Desktop/bogus.list" > "$HOME/Desktop/output.list"
