Append next line

[clemhoff]

Hello,

I'm trying to append a line to previous if it doesn't begin with a equal sign

Input
...
=POUILLY SUR VINGEANNE
=2006
0628
59.9370-111
25.619
=45370
...

Expected Output:
...
=POUILLY SUR VINGEANNE
=2006|0628|59.9370-111|25.619
=45370

What I've tried so far:

awk '/^=/ {if (line) print line; line=""}{line = line $0"|"} END {if (line); print line }'

concatenation works but unfortunately I get a vertical bar on every line (

Can you please point my error ?!
Thank's in advance.

String concatenation is performed simply by juxtaposition.

# wrong
line = line $0"|"
# right
line = line $0

My way:

awk 'BEGIN{ORS=""} NR>1 && /^=/{print RS} 1 END{print RS}'

Thank you Futurelet for your answer

I tried your code, but I'm loosing the delimiter (vertical bar)
I get this
=2006062859.9370-11125.619

instead of:
=2006|0628|59.9370-111|25.619

you may try this:

awk '/^=/{if (line)print line;line=""}{line=line (line?"|":"")$0}END{if(line)print line}'

Hope This Helps, PH.

Yes, I definitively missed the logical condition...

Once again, thank you PHV for help, that works a treat.

 

[futurelet]

Sorry. Overlooked that.

awk 'BEGIN{ORS=""} NR>1{print /^=/? RS:"|"}
 1 END{print RS}' myfile

No problem Futurelet !
Your proposal works too. Thank you very much
