SED - log file format
Hello everyone,

I have a log file :
Code:
\data\file\script\command_0001
\data\file\script\command_0002
\data\file\script\command_0003

I need to make all lines on this way

Code:
\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

Code:
\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 ?

Code:
\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
Code:
tr "\n" " " <infile

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