Question

Here is an example of the data:

I am in need of a script to remove the new line character from lines that do not begin with a timestamp. In the example above, lines 2-5 would be appended to the last field in the first line in a sort of text blob. I know how to detect the good lines,

grep '^[0-9][0-9][0-9][0-9].*' testfile

and also the bad lines,

grep '^[^0-9][^0-9][^0-9][^0-9].*' testfile

The question now is, how do I apply this (using sed?) in order to put the lines following a 'good' line back into the last field of this line. Any help here would be much appreciated.

Here is an example of the desired output:

Edit:

There is some disagreement as to which is the most appropriate tool. At the moment I am leaning towards notepad++. This is close to the kind of thing I want to do but it is not quite working, maybe someone out there can help me tune it to my use case:

(?! [0-9]{4}\-[0-9]{2}-[0-9]{2}).*

(?! [0-9]{4}\-[0-9]{2}-[0-9]{2})  - searches for a line not like a timestamp
.*                                  - followed by anything else

The problem is that the .* catches the timestamp that I am attempting to negate. Any thoughts?

Edit 2: Thanks everyone for the helpful advice, it's definitely moving me in the right direction! The following regex finds the problematic \\n char in notepad++, but when I try to perform the substitution nothing happens:

Find: (.*)(\n)(?![0-9]{4}\-[0-9]{2}\-[0-9]{2})
Replace: \1

Does anyone have any ideas here as to how to force notepad++ to remove the problematic \\n?

Edit 3: Here is additional sample data that does not seem to work with the proposed solutions:

If that's not your expected output, please update your question to show what it is.

Answer 2

Simplest solution:

echo $(cat file) | sed -re 's/(2013-06)/@@@\1/g' | sed -re 's/@@@/\n/g'

This works because echo without quotes put everything in the same line, then we insert @@@ before the timestamp and the replace @@@ with new line character.

tiago@dell:~$ echo $(cat file) | sed -re 's/(2013-06)/@@@\1/g' | sed -re 's/@@@/\n/g'

Answer 3

I am not sure what you like to do, since you have not provided with output example.
But if you like to connect lines, you can try this awk

awk '{printf (!/2013/?" ":RS)"%s",$0} END {print ""}'

Answer 4

Here is one way using GNU sed :

sed -nr ':a;N;/\n[0-9]{4}-[0-9]{2}-[0-9]{2}/{P;$!D;s/.*\n//p};s/\n/ /g;$!ba;p' file

Explanation:

• Create a label :a
• Append next line to current line on pattern space using N
• /\\n[0-9]{4}-[0-9]{2}-[0-9]{2}/{P;$!D;s/.*\\n//p} Test if the line that is appended starts with date if so print up to the first newline and if it is not the last line, delete up to first new line. If it is the last line delete up to the newline and print it.
• s/\\n/ /g; for all other lines keep removing new lines.
• ba branch back to our label and repeat

Answer 5

This might work for you (GNU sed):

sed ':a;$!N;/^[^|]*$/Ms/\n/ /;ta' file

If the last line appended does not contain a | replace the newline with a space and repeat.
