SED - log file format

Shell Programming and Scripting
1

Hello everyone,

I have a log file :

\data\file\script\command_0001
\data\file\script\command_0002
\data\file\script\command_0003

I need to make all lines on this way

\data\file\script\command_0001 \data\file\script\command_0002 \data\file\script\command_0003

I know this could be done with SED. But I am lost. Could you please help me on this ?

Thanks

Dear Friends,

If I may I have another question - The last one. Is there a way to make the file like it was ?

I have now

\data\file\script\command_0001 \data\file\script\command_0002 \data\file\script\command_0003

Is there a way to make it back like it was ?

\data\file\script\command_0001
\data\file\script\command_0002
\data\file\script\command_0003

Sorry for that question, but I have a huge amont of lines and I want to be sure that there is no corruption of that file.

Thanks

if

tr "\n" " " <infile

TRanslates newline ('\n') into spaces (' '), what do you think needs to be done to do the opposite?

Dear vgersh99,

I know that you are always around helping us :slight_smile: . Thanks for your reply.

It's about 20000 lines and I am too tired to check the all way to see if no line is missing or damaged. Your right, I will try to reverse the command line. I will see ...

Thanks vgersh99

code to put all the lines in one line:-

nawk  -v ORS=" " '{print $0}' input_file
