Shell Programming and Scripting

so i have several files that look somewhat like this:

Code:

{
  "afafa": "afaf",
  "afafaa" : ""
}

<newline>
<newline>

i want to grab everything in the file except the empty new lines at the end. note, there may be newlines within the content itself.

Code:

(
  "afafa": "afaf",
<newline>
  "afafaa" : ""
<newline>
}

<newline>
<newline>

that's ok. i only want to avoid the new lines at the end, after the last "}".

Here is the awk command i've been trying to use, but im not quite there yet:

Code:

awk '/[[:blank:]]{/,/\}[[:blank:]]/' nbApp.json

any ideas?

I find using an open parenthesis matched by a closing brace strange, but maybe something like:

Code:

awk '
/[(]/,/[}]/ {print;next}
!/^[[:blank:]]*$/
' nbApp.json

will do what you want???

thank you. that was my mistake. the parenthesis should have been an open "{". i've fixed it.

Are those "<newline>" strings (9 char) or single <NL> (0x0A) characters?
